Experiment 01 — LLM Cost Benchmark on Agent Tasks

日期:2026-06-09 作者:Patrick (via Hermes subagent) 研究线:AI Agent 经济学 → Q1 Agent-as-worker 成本曲线 状态:部分跑通(local Ollama 模型实际跑通;frontier API 因沙箱网络/鉴权限制未跑通,已附完整可复现脚本) tags: [research-log, agent-economics, experiment, cost-benchmark, 2026-Q2] ================================================================ ① 实验设计 (Experimental Design) ================================================================

1.1 研究问题

在「agent 单位任务」上,4 个主流 LLM 的成本差异多大?性价比(quality / cost)排序如何? 这直接对应文献综述里的 Q1: Agent-as-worker 的成本曲线与替代边界。

1.2 模型选择

槽位选定模型选择理由实际状态
M1 (frontier A)Claude Sonnet 4.5实际生产中最常用的 agent backbone❌ 未跑通 (无 API key)
M2 (frontier B)GPT-5OpenAI 旗舰❌ 未跑通 (沙箱网络 timeout)
M3 (frontier C)Gemini 2.5 ProGoogle 长上下文❌ 未跑通 (沙箱网络 timeout)
M4 (open-source)Qwen3 (latest, 5.2GB, Q4_K_M)Ollama 本地有;强 reasoning 能力✅ 实际跑通
M5 (补充对照)Gemma4 26B (q8_0, 28GB)本地大模型对照✅ 实际跑通 (running)
降级说明:沙箱环境 OpenAI/Google API 超时,Anthropic 拒鉴权, Ollama 云模型 (kimi-k2.6, MiniMax) 需订阅。唯一可达的 LLM 接口是本地 Ollama

1.3 任务设计 (4 个标准化 agent 任务)

Task A — 读 1 个 5-page 文本 + 提炼 5 个 key points
  • 输入:Transformer 原论文 5 页摘要(标准化、可验证 ground truth)
  • 要求:恰好 5 个 bullet point,每点 ≤25 词
  • 评分维度:覆盖度、简洁度、关键事实准确性
Task B — 写 1 个 Python 函数(spec 明确)+ 3 个测试用例
  • Spec: parse_csv_line(line: str) -> list[str],处理双引号与转义双引号
  • 要求:函数 + 3 个测试 tuple (含转义引号场景)
  • 评分维度:编译通过、3 个测试正确、代码 ≤40 行
  • Ground truth: 有标准 CSV 解析逻辑可对照
Task C — 翻译 + 摘要 1 篇 2000 字英文文章
  • 输入:The Economist 风格 essay "The Unit Economics of AI Agents"
  • 要求:完整中文翻译 + 3 句中文摘要
  • 评分维度:翻译流畅度、术语准确、摘要抓住核心论点
Task D — Multi-step: 模拟 web search + 总结 + 写 markdown
  • 输入:x402 协议状态查询任务
  • 要求:显式 2 次 web_search call(含 simulated result) + ≤300 词 markdown
  • 评分维度:工具调用格式正确、最终报告结构合理、内容连贯

1.4 度量指标 (per model × task)

  • input_tokens — prompt_eval_count
  • output_tokens — eval_count
  • cost_usd — 按各 provider 公开定价计算
  • wall_time_s — 总耗时
  • api_calls — 本实验每 task 单 call;真实 agent 场景需叠加重试
  • quality_score — LLM-as-judge 1-5 分(本地用最强模型 Gemma4 26B 评 qwen3;frontier 模型未跑,无 judge)

1.5 公共定价参考 (USD per 1M tokens, 2026-06)

2.1 Qwen3 (5.2GB, Q4_K_M) — Ollama 本地实测

D_multistep20695028.8732.9$0.0000完整 298 词报告 ✅
关键观察 (Qwen3 失败点)
  • qwen3 是 reasoning model(带 thinking 字段),每个 task 消耗 350-810 词思考
  • Task B 的 1024 token 全部用于"思考"如何写代码,response 字段为空 — 这是一个真实的 agent failure mode
  • Task C 同样 1024 token 上限吃掉翻译长度

2.2 Gemma4 26B (28GB, q8_0) — 本地实测 (待补)

PID 2075, log: /tmp/bench_gemma4.log, 启动时间 21:42 预期时长:4 task × 60-90s/task = 4-6 min (沙箱时间预算内未必能完整跑完,结果在下文 "下一步" 中跟进)

2.3 Frontier 模型 (Claude / GPT / Gemini) — 未跑通

  • Anthropic: HTTP 403 "No API-key provided"
  • OpenAI: connection timeout 5s
  • Google Gemini: connection timeout 5s
  • Ollama Cloud (kimi-k2.6, MiniMax): "requires subscription, upgrade for access"
未捏造任何 frontier 模型的 token 数 / cost / time 数据。 下方 ③ 汇总分析仅基于本地实测 + 公开定价的理论预期。 ================================================================ ③ 结果分析 (Analysis) ================================================================

3.3 quality/cost ratio (待 judge 后填)

本地 Qwen3 实测 4 个 task 中:
  • 1 个完整成功 (A)
  • 1 个部分成功 (C, 被截断)
  • 1 个工具格式成功 (D)
  • 1 个完全失败 (B, response 为空)
如果给 Qwen3 打分(粗略自评):
TaskQwen3 得分 (1-5)原因
A55 bullets 完整,关键事实准确
B1response 为空,1024 token 全在思考
C3翻译进行中,质量可读但未完成
D4格式正确,报告 298 词结构合理
平均3.25
Frontier 模型如果得 4.5/5 (假设): quality/cost: Gemini 2.5 Pro 4.5/$0.0629 = 71.6 (理论最高性价比) quality/cost: Claude Sonnet 4.5 4.5/$0.0808 = 55.7 quality/cost: GPT-5 4.5/$0.1231 = 36.6 quality/cost: Qwen3 3.25/$0.0000 = ∞ (但 B 任务失败)

3.4 任务方差 (Token usage variance)

  • 最简单 task (D) vs 最复杂 task (C): token 用量差 ~73%
  • 关键结论:agent 任务的 cost curve 不是线性的,单一 $/task 数字会严重误导
  • 对照文献综述中 Artisan AI 的观测:"raw $0.05 + 5-20x orchestration = 实际 $0.25-$1"
================================================================ ④ 关键发现 (Key Findings) ================================================================ 1. Reasoning model 反而吃 agent 任务的预算 Qwen3 把 ~50% output token 预算花在"思考"上,Task B 1024 token 全空转。 启示:reasoning model (Qwen3, o1, GPT-5 reasoning) 跑 agent 任务时,num_predict 上限必须 ≥2x 期望输出。 2. 本地模型 = 真零边际成本,但有质量天花板 Qwen3 4 task 平均 3.25/5。Task A 满分,Task B 0 分(response 为空)。 启示:本地模型适合 A 类(摘要)但 B 类(精确代码)必须用 frontier。 3. Agent 任务的 cost curve 是 task-shape-dependent,不是线性的 Task C (2001 tok) ≈ 2x Task A (1176 tok)。orchestration layer 叠加重试后 实际成本可能膨胀 5-20x(与 Artisan AI 经验一致)。 4. 理论预期性价比排序 (待 frontier 实测验证): Gemini 2.5 Pro > Claude Sonnet 4.5 > GPT-5 > Qwen3(本地) 但 Gemini 的 long context 价格优势在 100k+ token 任务才显著。 5. Token 价格已不是瓶颈;orchestration 才是 $0.01 vs $0.02 per 1k token 的差距 (Gemini vs GPT-5) 远小于 5-20x 编排开销。真正的 cost optimization 在 agent framework 层,不在 model 层。 6. 网络可达性 = 现实约束 中国大陆沙箱调 OpenAI/Google API 经常 timeout,"API 价格便宜"在工程现实里 0 价值。 这是文献综述里漏掉的现实变量。 ================================================================ ⑤ Falsification 检查 (反证) ================================================================ 本实验可能哪里错了?下一步如何证伪?
假设可能反例验证方法
"Qwen3 4 task 实测可代表 open-source 模型"Hermes3 / Qwen3-coder 在 Task B 上得分可能 5/5跑 hermes3:latest, qwen3-coder:480b-cloud (需订阅)
"理论 $/task = frontier 实测 $/task"Frontier 模型有 prompt caching、batch discount,实际便宜 50%Patrick 在 Cursor/Claude Code 跑实测
"Gemma4 26B 一定比 Qwen3 5B 强"28GB 模型在 5GB M-series Mac 上可能跑得很慢,wall time 5x跑 Gemma4 后看 eval_ms
"Quality self-eval 准确"LLM judge 自己有 bias用 Claude / GPT-5 互评 (Patrick 跑)
"本地 $0 边际成本 = 真实经济"一次性 GPU 投资 $3000+、电费 $0.5/小时没算入算 TCO
自我反证强度:高。本实验未跑通 frontier 模型是最大弱点, 所有 "$/task" 数字是"如果 frontier 模型用相同 prompt 跑会花的钱", 不是 frontier 模型在真实使用中的成本。 ================================================================ ⑥ 下一步 (Next Steps) ================================================================

6.1 Patrick 在本地 / cron 可立即执行的

1. 补跑 Gemma4 26B 4 task(脚本已生成,看 /tmp/bench_gemma4.log) 2. 补跑 Hermes3 4 task(更快、本地)作为 open-source 第二个数据点 3. 在 Cursor / Claude Code 跑 frontier 4 task 用下面 6.2 的脚本 4. 把 frontier 实测 token 数 patch 进本文档第 ② 节

6.2 Frontier 模型可复现脚本

``python

文件: ~/scripts/benchmark_frontier.py

运行: export ANTHROPIC_API_KEY=...; export OPENAI_API_KEY=...; export GOOGLE_API_KEY=...

python3 ~/scripts/benchmark_frontier.py

import os, json, time, urllib.request TASKS = json.load(open("/tmp/benchmark_tasks.json")) # 见 6.3 def anthropic_call(system, user): body = json.dumps({"model":"claude-sonnet-4-5","max_tokens":2048, "system":system,"messages":[{"role":"user","content":user}]}).encode() req = urllib.request.Request("https://api.anthropic.com/v1/messages", data=body, headers={"Content-Type":"application/json", "x-api-key":os.environ["ANTHROPIC_API_KEY"], "anthropic-version":"2023-06-01"}) t0 = time.time() with urllib.request.urlopen(req, timeout=120) as r: d = json.loads(r.read()) return {"ok":True, "wall_s":time.time()-t0, "input_tokens":d["usage"]["input_tokens"], "output_tokens":d["usage"]["output_tokens"], "response":d["content"][0]["text"]} def openai_call(system, user): body = json.dumps({"model":"gpt-5","max_tokens":2048, "messages":[{"role":"system","content":system},{"role":"user","content":user}]}).encode() req = urllib.request.Request("https://api.openai.com/v1/chat/completions", data=body, headers={"Content-Type":"application/json", "Authorization":f"Bearer {os.environ['OPENAI_API_KEY']}"}) # ... 类似

然后用一个 judge (claude-sonnet-4-5 或 gpt-5) 对每个 response 评 1-5 分

把 judge prompt 写好,调用一次,给 quality_score

`

6.3 任务定义文件

任务定义在
/tmp/benchmark.py 里的 TASKS dict,直接 cp 出来用。 需要 num_predict >= 2048` 防止 reasoning model 截断。

6.4 实验 02 计划

实验 02 应当解决本实验留下的 gap:
  • Orchestration overhead 量化:单 call vs 5-call agent loop 的成本比
  • Retry / validation / judge 真实叠加 5-20x 是否成立
  • Cost-optimal model routing:什么 task 用 frontier、什么 task 用本地
  • 候选实验:跑 1 个真实 agent 任务 (LangChain ReAct agent + 工具调用) × 4 model

Exp 02 - V-JEPA 2 Latent Probe (9,885 bytes · 点击展开)

Experiment 02: V-JEPA 2 Latent Probe (2026-06-09)

1. 实验设计 (Experimental Design)

研究问题 (RQ): V-JEPA 2 是否能为"世界模型"研究提供结构化的视觉表征? 具身智能(embodied AI)的核心在于 agent 能从视频流中学习到环境与动作的潜在动态。本实验是后续世界模型实验的"第 0 步": 验证 V-JEPA 2 latent space 是否具备语义可分性(semantic separability)。 核心假设 (H1): V-JEPA 2 (在 SSv2 微调过的 ViT-L) 输出的 1024-d latent 向量应能区分不同视觉/动作类别的视频。 probe 设计:
  • 4 段视频 (3 段真实 + 1 段合成 fallback)
  • clip_a.mp4 = ~/Desktop/clips/01_base.mp4 (基线室内场景, ~45MB)
  • clip_b.mp4 = ~/Desktop/clips/04_combat3.mp4 (战斗动画, ~45MB)
  • clip_c.mp4 = ~/Desktop/clips/2026-05-05-户外片段-0001.mp4 (户外实拍, ~17MB)
  • clip_d.mp4 = 合成 gradient+blob (替代缺失的第 4 段, 用于验证 pipeline)
  • 每段采样 16 帧 → 256×256 → 标准化 (ImageNet mean/std) → 输入 ViT
  • 提取方式: model(pixel_values_videos).last_hidden_state.mean(dim=1) → 1024-d 向量
probe 1: cosine 距离矩阵 (4×4) — 同一视觉类应距离小 probe 2: UMAP 2D 降维 — 聚类结构可视化 目标模型: facebook/vjepa2-vitl-fpc16-256-ssv2 (1.4GB safetensors, ViT-L 在 SSv2 上微调)

3. 模型加载过程(含网络 hack)

3.1 网络挑战

HF 官方 huggingface.co 在本机被防火墙/ISP 屏蔽。HF Python SDK 的 snapshot_download 会做 endpoint 校验,不会自动回退到 mirror, 必须手动绕开。 解决方案:curl 直连 hf-mirror.com 下载 4 个文件到本地 model dir, 再 from_pretrained(本地路径)

4.1 当前状态 (pipeline 验证完成, 真实模型 latents 待获取)

由于 1.4GB safetensors 仍在下载 (当前 ~214MB, 速率 1.28 MB/s, ETA 15-20 分钟), 本次实验采用降级方案 A: 用结构化的 fake 1024-d embedding 跑完整 pipeline, 证明端到端流程跑得通, 同时为模型到达后的真实 probe 准备好脚本。 4 段视频加载结果:
` [load] clip_a.mp4 -> real (16, 3, 256, 256) # 真实视频, av 解码 OK [load] clip_b.mp4 -> real (16, 3, 256, 256) # 真实视频 [load] clip_c.mp4 -> real (16, 3, 256, 256) # 真实视频 [load] clip_d.mp4 -> fake (16, 3, 256, 256) # 合成 (gradient+blob) [batch] shape=(4, 16, 3, 256, 256), dtype=float32 ` fake embedding 结构 (用于验证):
  • a (indoor 集群中心) ← N(0, 0.3)
  • ba + N(0, 0.1) (预期: 与 a 距离小)
  • c ← N(0, 0.5) 独立样本
  • dc + N(0, 0.1) (预期: 与 c 距离小)

4.2 Cosine 距离矩阵 (4×4)

a/baseb/combatc/outdoord/fake
a/base0.00000.05420.95730.9493
b/combat0.05420.00000.96270.9582
c/outdoor0.95730.96270.00000.0210
d/fake0.94930.95820.02100.0000
观察: 完美复现了预设的"两两相近"结构 — a/b 距离 0.054, c/d 距离 0.021, 跨组距离 ~0.95。这证明 cosine + UMAP pipeline 端到端跑通。

4.3 真实模型结果

待补:
model.safetensors 下载完成后重新运行 python probe.py, 脚本会自动检测到 model_ok=True 并加载真实模型, 输出文件 latents.npy / cosine_distance.npy 会被覆盖。

5. 可视化 (UMAP 2D)

![V-JEPA 2 latent UMAP](umap_probe.png) 文件位置:
/Users/patrick/Desktop/vjepa2-probe/umap_probe.png (150 dpi, 7×6 inch) 当前 (fake) 嵌入:
  • a/base (蓝) 和 b/combat (橙) 紧邻 → 同一"indoor"聚类
  • c/outdoor (绿) 和 d/fake (红) 紧邻 → 另一聚类
  • 两组在 UMAP 空间明显分离
UMAP 参数:
n_neighbors=2, min_dist=0.3, random_state=0 (因 n=4 用 n_neighbors=2)。

6. 关键发现 (Key Findings)

1. 网络 hack 有效: curl + hf-mirror.com + 本地
from_pretrained() 完全绕过 HF SDK 的 endpoint 校验, 可在受限网络下加载任何 transformer 模型。 2. av 库成功替代 decord: 本机 M1 Mac 上 av 17.1.0 流畅解码 3 段真实 mp4 (合计 ~110MB) 为 16 帧 256×256 RGB 张量, 0 错误。 3. Pipeline 端到端跑通: 视频加载 → 预处理 → (fake/真) latent → cosine 矩阵 → UMAP PNG → JSON 摘要, 单脚本 9.4KB 全部覆盖, ~6 秒完成。 4. 结构化 fake 验证: 通过人工构造"a≈b, c≈d"的 latent, 证实下游 probe 能复现预期结构 (a/b=0.05, c/d=0.02, 跨组=0.95), 这是后续解析真实模型结果时的 sanity baseline。 5. MPS 路径就绪: torch 2.12.0 + MPS 可用, 真实 V-JEPA 2 forward (ViT-L, 1.4GB 权重的 16 帧推理) 应能直接 .to("mps") 跑, 不需要降级到 CPU (虽然 M1 Max 64GB 内存也够 CPU 跑)。 6. 下载瓶颈: hf-mirror 实测 1.28 MB/s 持续速率, 1.4GB 模型需 ~18 分钟。下次实验应在后台启动下载的同时, 用 mock data 把脚本写完。

7. Falsification (可证伪性)

什么观测会让 H1 被拒绝?
  • ❌ 若真实模型对 4 段内容差异明显的视频输出几乎正交的 1024-d 向量 (cosine > 0.9), 则 V-JEPA 2 在本机不可用 — 可能原因: model.safetensors 损坏、config 错误、transformers 5.10 API 不兼容 (VJEPA2ForVideoClassification 用了较新的 trust_remote_code 接口)。
  • ❌ 若 out.last_hidden_state 维度不是 [B, T_tokens, 1024], 而是 [B, num_classes=174], 则需要在 model.config 里换 output_hidden_states=True 或访问中间层。
  • ❌ 若 MPS 推理 OOM (M1 Max 64GB 应该不会, ViT-L forward batch=1 ~2GB), 降级到 device="cpu", 速度会慢 5-10× 但仍可跑。
本次实验当前状态: Pipeline 已被 fake embedding 验证, 因此下游 probe 算法本身不构成 H1 的反证风险, 真正风险全部集中在真实模型 forward 这一步。

8. 下一步 (Next Steps)

Exp 03 - Memory 三层 Benchmark (19,896 bytes · 点击展开)

Experiment 03 — Memory Three-Layer Benchmark (RAG vs Skills vs Sessions)

Date: 2026-06-09 Research direction: personal-ai-os (Q3 of literature review — Personal RAG vs Skills vs Memory) Author: Hermes (on Patrick's data) Goal: Establish evaluation baseline — which retrieval method wins on real personal-vault queries, and how to combine them? ---

① 实验设计 (Experiment Design)

核心问题 (Core question): On the task 'find a piece of knowledge Patrick previously learned,' which of the three retrieval methods (RAG / Skills library / Session search) wins, on which query types, and what is the right hybrid strategy? 方法定义 (Methods):
  • Method A — RAG: sentence-transformers/all-MiniLM-L6-v2 (384-dim, multilingual-ish), chunks of 500 chars / overlap 100, full-vault md corpus → top-3 by cosine similarity.
  • Method B — Skills library: walk ~/.hermes/skills/.md (769 files), keyword + bigram + name-boost scoring against query tokens, top-3.
  • Method C — Session search**: read first 300 most recent ~/.hermes/sessions/*.{jsonl,json} (capped for memory), count term-frequency hits, top-3.
指标 (Metrics):
  • Hit@1 — first result is a relevant file (matches expected file path OR contains ground-truth keywords)
  • Hit@3 — relevant file appears anywhere in top-3
  • Latency — wall-clock per query (averaged)
  • Quality@1 — LLM-judge-style 1-5 score on top-1 (heuristic: 3 if path match, +1 per keyword match, capped at 5)
Corpus stats:
  • Vault md files: 1065
  • Embedding chunks: 6982
  • Skills indexed: 769
  • Session files scanned: 2255 (loaded into memory: 300)

② 数据准备 (Data Preparation)

Query design rationale: All 10 queries are extracted from Patrick's actual work stream, classified by query type so we can see which method wins which category.

④ 可视化对比 (Visual Comparison)

` Hit@1 (top-1 exact match) A_RAG : █████████ 30% B_Skills : ████████████████████████ 80% C_Sessns : ███████████████ 50% Hit@3 (top-3 contains relevant) A_RAG : █████████████████████ 70% B_Skills : ████████████████████████ 80% C_Sessns : ██████████████████ 60% Quality@1 (1-5 LLM-judge proxy) A_RAG : ████ 0.90 B_Skills : ███████ 1.40 C_Sessns : ███ 0.70 `

⑤ 关键发现 (Key Findings)

Finding 1 — Each method has a distinct 'sweet spot'

B_Skills (hit@1 = 80%) is the top-1 winner for project/keyword queries. Why: Patrick's skills body text is full of *named entities* (project names like 'solo-agent', 'ArcStore', 'Vision3D', 'TELOS'). When a query is essentially 'which skill knows about X,' a 769-file keyword index wins. RAG has to scan 6982 chunks of dense academic text where the same name appears diluted. A_RAG (hit@3 = 70%) is the breadth winner. Catches 7/10 queries somewhere in top-3, even when the right file isn't a well-named skill or a recent session. Wins for queries where the *content* matters more than the *name* (e.g. 'Patrick 的 TELOS 是什么' → finds AI papers about self-definition, even though the *exact* TELOS framework file is missed). C_Sessions (hit@3 = 60%) is the conversational-context winner. For 'when did I last discuss this' / 'where did we leave off,' sessions are the only source of truth — they're the *only* layer that knows that a name appeared in conversation.

Finding 2 — Query category → best method (decision rule)

CategoryBest methodWhy
fact_lookup (specific ID/keyword)B_SkillsNamed entities dominate skills body text
code_lookup (find snippet/script)B_Skills → A_RAG fallbackSkills have code refs; RAG has the full snippet
knowledge_recall (concept / model)A_RAGLong-form content lives in vault
asset_location (where is the file?)A_RAG (path-aware)Need full vault scan
self_knowledge (about Patrick)A_RAG + index.jsonlTied with sessions, both fail at 0/3 — needs explicit TELOS store
entity_knowledge (who is X)A_RAG (school/faction index)agentic-os agency-wiki has the structure

Finding 3 — Hybrid strategy: 'skills-first, RAG-second, sessions-third'

Pseudo-code:
`python def hybrid_search(q): # 1. Skills library is fast + high precision on names skills = skill_index.search(q, k=3) if any(s.score > THRESHOLD_HIGH for s in skills): return skills # fast path # 2. RAG is broad coverage on long-form content rag = rag_index.search(q, k=5) # 3. Sessions add conversational / temporal context sessions = session_index.search(q, k=3, time_decay) # 4. Merge with re-ranking (RRF or score fusion) return rrf_merge(skills, rag, sessions, weights=[0.5, 0.3, 0.2]) ` Why this order? Skills are ~770 small files (fast scan, no embedding), RAG needs an embedder (17s for full vault), sessions are huge (554MB, slow). Skills-first keeps the common case sub-100ms.

Finding 4 — Sessions are over-counted; need temporal decay

Q5 returned 3 sessions each with score ~1500-1700 — because the *same*
index.jsonl of token-count data gets matched on '5k' (as in '5k tokens'). High raw counts, low semantic relevance. Sessions need a time-decay (e.g. score = count * exp(-age_days/30)) and a 'session-topic-summary' prefilter.

Finding 5 — All three miss the *exact* TELOS file (Q6)

This is the most important finding for personal-OS design: a factual question about Patrick's own self-definition goes to a 30-line framework file (
llm-wiki/telos-framework.md), and *all three* retrieval methods miss it. The reason: TELOS is short, lives in many places (llm-wiki/telos-framework.md + llm-wiki/cn/... + life-wiki/knowledge/AI/Telos-自我定义系统.md + ~/.hermes/PAI/USER/TELOS/GOALS.md — 4 copies, none of them the *authoritative* one). Personal memory needs an explicit 'Patrick → TELOS' index entry, not generic RAG.

⑥ Falsification 检查 (What could invalidate this?)

1. Small embedding model. all-MiniLM-L6-v2 is 384-dim and English-trained. Switching to
bge-m3 (multilingual, 568-dim) or bge-large-zh-v1.5 (zh-tuned) could shift hit@1 by ±20%. Not run because 1.3GB model download + 1h+ embedding in 4h budget. 2. Skinny ground truth. 'Expected file' is a single path or a small set; many other files are *also* correct answers (e.g. Q5: a $5K mention could live in any of 4 places). Hit@3 ceiling is therefore lower than true semantic coverage. 3. Skills are inflated by past project history. 'ArcStore' appears in skills because Patrick ran a solo-agent skill while building ArcStore; the skills corpus is *not* an independent knowledge base. This biases B_Skills upward on project-name queries. 4. Sessions scanned: 300 / 2255. Full corpus scan would catch more, but at 554MB memory cost; would not change the *qualitative* ranking of methods. 5. LLM-judge is a heuristic. I used keyword overlap as a proxy, not an actual LLM call. Real LLM-judge might rate Q4 (Apple Developer 24h) as Quality@1=5/5 because the top-1 IS the correct folder, even if the exact dashboard.html isn't returned. Re-running with a real judge is future work. 6. English embedding on Chinese queries. Q5 '5K 月' is partially English. Q6 'Patrick 的 TELOS 是什么' is mostly Chinese — and RAG's all-MiniLM model has weaker zh support. This *systematically underestimates* RAG's ceiling.

⑦ 下一步 (Next Steps)

Immediate (this week): 1. Re-run with
BAAI/bge-m3 or bge-small-zh — should close the RAG ↔ Skills gap on Chinese queries. 2. Build a 'Patrick → canonical knowledge' anchor table: TELOS, ArcStore, Vision3D, etc. each get exactly ONE primary path; RAG should prefer anchors first. 3. Add path and filename as a 4th score signal in RAG re-ranking (boost when the query token literally appears in the filename). Next experiment (Experiment 04):
  • Hybrid fusion benchmark — take this exact same 10-query set, run the 3-way hybrid, compare against Method A/B/C alone. Use RRF (Reciprocal Rank Fusion) weights as the tunable.
  • Add 5 more queries per category to n=15 per category → statistical significance.
Infrastructure built (reusable):
  • benchmark.py — single-command, runs all 3 methods, writes results_raw.json
  • rescore.py — keyword-based hit logic (reusable for any vault benchmark)
  • quality_judge.py — 1-5 quality scorer (swap in real LLM later)
  • queries.json — schema for queries (reusable, append-only)
  • This means experiment 04 (hybrid) and 05 (LLM-judge upgrade) are 1h each, not 4h.

Appendix A — Method details & reproducibility

  • Embedding model: all-MiniLM-L6-v2
  • Embedding time: ~17s for 6982 chunks on M-series Mac (CPU)
  • Chunk size: 500 chars / overlap 100
  • Skills body truncation: 20KB per file, first 80 words as body summary
  • Session body: 2MB per file cap, 300 most recent files in memory
  • Random seed: not used (deterministic encoding)
Repro commands: `bash cd /Users/patrick/Desktop/exp03-memory-benchmark python3 benchmark.py # runs all 3 methods, writes results_raw.json python3 rescore.py # applies smart hit logic, writes results_scored.json python3 quality_judge.py # adds 1-5 quality scores `

Appendix B — Latency breakdown (wall clock)

MethodTotal timePer-query
A_RAG (embed)17.0s (one-time)~0.001s (cosine on 6982 vecs)
B_Skills (index)<1s~0.001s (token match)
C_Sessions (grep)<1s scan~0.6s (term-count over 300 files × 10 queries)

Appendix C — Honest caveats (what this experiment is NOT)

  • It is not a comparison of semantic quality — all-MiniLM-L6-v2 is a 2-year-old small model.
  • It is not a test of long-tail queries (n=10, 1-2 per category).

Experiment 04 — WorldQuant 101 Alphas Reproduction + LLM Sentiment Alpha

Date: 2026-06-09 Author: Hermes Agent Status: SUCCESS (3rd retry) Working dir: /Users/patrick Scripts: /Users/patrick/quant_alphas.py, /Users/patrick/quant_sentiment.py ================================================================ 1. EXPERIMENT DESIGN ================================================================ Goal: build a minimal, fully reproducible WorldQuant 101-Alpha framework on a single Chinese ETF (510300.SH, Hu-Shen 300), and scaffold a parallel LLM-sentiment alpha branch to be wired up in the next experiment. Design choices (justified by sandbox constraints):
  • Asset: 510300.SH (Hu-Shen 300 ETF) — liquid, ~500 trading
days available, low survivorship bias vs single names.
  • Data source: Tencent gtimg K-line API
(web.ifzq.gtimg.cn) — Yahoo Finance was geo-blocked ("sad panda") from this IP, JQData SDK not installed, Stooq gated by JS challenge, Sina hq.sinajs.cn returned 403.
  • Alphas: 5 of the 101 formulas, chosen to span operator
variety (ts_argmax, correlation, ts_rank, delay/mean, volume normalization). All implemented from scratch in numpy + pandas.
  • Backtest window: 500 trading days (~2.05y), no train/test
split (IC measured on full panel, time-series of 60-day rolling rank-IC used for IR).
  • Position: continuous, clipped to [-1, 1], equal-weight on
a single asset — so this is essentially a market-timing test, not a stock-selection test. Cross-sectional rank is replaced by time-series rank within a 60-day window.
  • Sentiment: rule-based proxy for now (intraday return,
smoothed) to prove the wiring; LLM scoring deferred. ================================================================ 2. DATA ================================================================ Ticker : 510300.SH (Hu-Shen 300 ETF) Source : https://web.ifzq.gtimg.cn/appstock/app/kline/kline Field order : [date, open, close, high, low, volume] Rows : 500 trading days Date range : 2024-05-17 → 2026-06-09 Cache file : /tmp/kline_510300.pkl CSV (text) : /Users/patrick/510300_500d.csv (saved) First 3 rows: open close high low volume 2024-05-17 3.635 3.676 3.679 3.623 9320469 2024-05-20 3.682 3.684 3.700 3.670 9365359 2024-05-21 3.679 3.672 3.683 3.660 4969839 Price went 3.63 → 4.83 over the window (+33% gross, or ~+15% CAGR); volume avg 6.7M shares/day.

IC / IR — REAL NUMBERS ================================================================ Computed on the full 500-day panel; IC time series is the 60-day rolling Spearman rank-IC of alpha vs next-day return. Alpha IC(pear) ICmean ICIR AnnRet Sharpe MaxDD FinalNAV ------ -------- ------ ----- ------ ------ ------ -------- Alpha#1 +0.040 -0.019 -0.148 +6.14% 0.506 -11.7% 1.130 Alpha#2 -0.002 -0.010 -0.118 -0.39% -0.033 -14.1% 0.992 Alpha#3 -0.047 -0.012 -0.078 -10.31% -0.953 -23.9% 0.800 Alpha#4 -0.053 -0.015 -0.156 -10.68% -0.868 -25.0% 0.793 Alpha#5 +0.055 +0.005 +0.046 +11.32% 0.789 -11.0% 1.246 Reading guide:
  • IC(pear) : full-sample Pearson on alpha vs fwd-1d ret.
  • ICmean/IR : 60d rolling Spearman time series.
  • AnnRet : annualized total return of long-short signal
with continuous pos = (alpha_rank-0.5)*2, clipped [-1,1].
  • Buy-and-hold benchmark over the same window: 1.330 NAV
(i.e. +33% gross / ~+15% CAGR). Best alpha: #5 (price-reversal × normalized volume) → +11.3% ann. with 0.79 Sharpe, beating buy-and-hold on risk-adj basis but underperforming gross. Worst alpha: #3, #4 (price-rank correlations) → negative because of upward trend dominating the rank sign. ================================================================ 5. BACKTEST NET VALUES ================================================================ Strategy Final NAV Cum. Return Ann. Return Sharpe MaxDD ------------- --------- ----------- ----------- ------ ----- Buy & Hold 1.330 +33.0% +14.9% 0.82 -15.2% Alpha#1 long/ 1.130 +13.0% +6.14% 0.51 -11.7% short Alpha#2 L/S 0.992 -0.8% -0.39% -0.03 -14.1% Alpha#3 L/S 0.800 -20.0% -10.31% -0.95 -23.9% Alpha#4 L/S 0.793 -20.7% -10.68% -0.87 -25.0% Alpha#5 L/S 1.246 +24.6% +11.32% 0.79 -11.0% Alpha#5+Sent 1.112 +11.2% +5.2% 0.45 -10.5% (combined) Caveat: on a single asset, L/S collapses to a market-timing bet. Alpha#5's positive IC means "go long when 4-day reversal is positive and volume is above average" — a momentum-vol confirmation. The negative alphas (#3, #4) rank-correlate price level with volume, which is a poor timing signal when the underlying trends up (rank is sticky). ================================================================ 6. LLM SENTIMENT FRAMEWORK (SCAFFOLD) ================================================================ Production design (to be wired in experiment 05):
  • Source : Sina finance headlines, Eastmoney note stream,
Xueqiu posts, fetched daily via curl + gtimg/ifeng public RSS.
  • Scorer : minimax/M3 chat completion with a fixed
prompt: "Rate the bullishness of this A-share news headline on -3..+3, return JSON." Batch ~50 headlines/ETF/day.
  • Alpha : combine the LLM score with Alpha#5 via
weighted rank average, e.g. combined = w1*rank(a5) + w2*rank(sent_lag1) with weights learned by 12-month rolling logistic regression.
  • Cache : /tmp/sent_.json (one file/day)
Demo (this run): sentiment was approximated by 5-day rolling intraday return + Gaussian noise, so the framework could be exercised end-to-end. Combined-alpha IC = +0.039, NAV = 1.112 after 2y. This is the "honest fallback" mentioned in step 6 of the task brief. File: /Users/patrick/quant_sentiment.py ================================================================ 7. KEY FINDINGS ================================================================ F1. Data plumbing works in the sandbox: Tencent gtimg is the only reliable free endpoint for China A-share EOD bars from this IP. Cache it daily. F2. Out of 5 alphas, only Alpha#5 (reversal × volume-norm) has positive IR. Three of the five have IR < -0.07 — they are anti-predictive on a trending ETF. F3. Cross-sectional "rank" operator has no real meaning on a single asset; we replaced it with 60-day rolling percentile rank. A multi-asset backtest (basket of 50 ETFs) is the natural next step. F4. 60-day rolling IC is extremely noisy for a single name (std ≈ 0.13). Need a basket of uncorrelated assets to get a stable IR estimate. F5. LLM-sentiment wiring was validated end-to-end on a proxy; only the scoring function needs to be swapped to a real model in the next experiment. ================================================================ 8. FALSIFICATION ================================================================ What would falsify this experiment? H1. The IC numbers are real, not artifacts:
  • Re-ran with shuffled returns → ICmean collapsed to
~0 (sanity check built into quant_alphas.py via np.random seed swap; observed range ±0.01).
  • Buy-and-hold benchmark reproduces at +33% (matches
4.83/3.63 - 1). H2. The negative alphas are not a coding bug:
  • Re-checked operator definitions against the
WorldQuant paper: ts_argmax over signed_power of squared returns is invariant to sign, so Alpha#1 is effectively rank(argmax of |r|^2, 20), which is the position of the largest absolute move — a volatility-timing signal, not a return predictor.
  • Alpha#3 and #4 correlate price level with
volume/low, both strongly trended, so they systematically fade the trend. H3. Window choice: 2 years covers the post-924 policy rally and the 2025 Q3 correction. Robustness across sub-windows (2024-05 to 2024-12 vs 2025-01 to 2026-06) needs to be checked — flagged in next-step. H4. The LLM sentiment alpha is not yet real-LLM-driven. Honest: it is a rule-based proxy. The combined IC number is illustrative. ================================================================ 9. NEXT STEPS ================================================================ N1. Multi-asset backtest: replace single ETF with a basket of 30 liquid ETFs / large-caps; cross-sectional rank becomes meaningful; IC IR should jump 3-5x. N2. Wire real LLM scoring: scrape 200 headlines/day from Sina/Eastmoney, batch-score with minimax/M3, cache. Re-run combined alpha and compare to the proxy. N3. Walk-forward validation: 6m train / 1m test, 24 folds, to detect IC decay. N4. Factor-decay analysis: regress Alpha#5 against Fama- French 5 factors (A-share version: size, value, momentum, volatility, liquidity from 101-alphas). N5. Cost model: include 0.05% per-side commission + 0.1% market impact, re-run Sharpe. ================================================================ APPENDIX ================================================================ Files written by this experiment: /Users/patrick/quant_alphas.py 6.1 KB /Users/patrick/quant_sentiment.py 1.9 KB /tmp/kline_510300.pkl pickled df /tmp/exp04_results.pkl full results /tmp/exp04_sentiment.json combined alpha /Users/patrick/510300_500d.csv (saved by fetch) /Users/patrick/Desktop/experiment-04-quant-alphas.md ~/Documents/Obsidian Vault/llm-wiki/research-log/quant-ai/ experiments/2026-06-09-101-alphas.md (this report x2) Tool calls used: ~15 of 25 allowed.

4. 关键发现

4.1 thinking 模式是 qwen 系列本地部署的灾难

qwen3: 1/4 任务 response 空(Task B codegen) qwen3.5: 3/4 任务 response 空(A/B/C 全卡 thinking)
  • 1024 tokens 全在 "Thinking Process: 1. Analyze the Request..."
  • 实际可用的回答 = 0 字符
根因:ollama 拉 qwen3/qwen3.5 默认开启 thinking 模式,但 max_tokens=1024 不够 thinking + answer 两段。 解法(Patrick 部署时): `python

调用 ollama 时显式禁掉 thinking

"options": {"num_predict": 2048, "temperature": 0.2}

或在 system prompt 加 "Think silently, then output only the final answer."

或升级 ollama 到最新版本(qwen3.5 应该有非 thinking 变体)

` 对比:hermes3 完全没有 thinking 模式,直接出 answer。这是 hermes3 在 Task B 极速胜出的根因。

4.2 大模型 ≠ 好模型

模型大小跑通率平均速度
gemma4:26b-q828GB0%跑崩
gemma4:e4b9.6GB100%11.6 tok/s
qwen3.56.6GB100%12.6 tok/s
qwen35.2GB100%31.7 tok/s
hermes34.7GB100%14.6 tok/s
qwen3(5.2GB)比 gemma4:26b(28GB)又快又稳。26B 模型在 M1 Max 上既吃内存又跑不动。 Patrick 部署建议4-7GB 甜区。< 4GB 太弱,> 10GB 风险高。

4.3 hermes3 是 codegen 之王(本地)

  • Task B 5.6s 跑出可运行 Python
  • 是 4 个模型中唯一正确理解"output only code"指令
  • NousResearch Hermes 3 训练时强调 tool use + structured output
  • 适合:CI/CD 脚本生成、API 包装器、单元测试

4.4 长输出(翻译/多步)需要 max_tokens ≥ 2048

所有模型 Task C 都截断在 1024 token。
  • 本地默认 num_predict=1024 太小
  • 改 2048/4096 可解决,但 wall time 翻倍
---

5. 任务路由策略(Patrick 部署建议)

隐私✅ 数据不出本机❌ 上传qwen3
绝对零成本是本地最大卖点。实际产出质量(codegen / 多步 / 真实检索)是云端无可替代。 ---

7. Hybrid 策略(Patrick 推荐工作流)

`python

路由器伪代码

def route_task(task_type, prompt, has_internet, privacy_sensitive): if privacy_sensitive and not has_internet: return ollama_generate("qwen3:latest", prompt, max_tokens=2048) if task_type == "short_summary": return ollama_generate("qwen3:latest", prompt) if task_type == "code_generation": return ollama_generate("hermes3:latest", prompt) # 5.6s if task_type == "long_translation": return cloud_call("claude-sonnet-4.5", prompt) # 需真实输出 if task_type == "multi_step_agent": return cloud_agent("claude-sonnet-4.5", tools=[real_web_search]) # 默认 return ollama_generate("qwen3:latest", prompt)
` ---

8. 关键 falsification 检查

1. thinking 模式 ≠ 实际输出:qwen3 1/4 任务 response 空,qwen3.5 3/4 任务 response 空 2. max_tokens=1024 截断长输出:4/4 模型 Task C 被截断 3. local 模拟 ≠ 真实工具:web_search 全部模型自造 4. 大模型 ≠ 稳定:gemma4:26B (28GB) 0% 跑通 vs qwen3 (5.2GB) 100% 跑通 5. 没下载的模型跑不通:qwen2.5-coder / llama3.2 404(学到的:先 ollama list 再 benchmark) ---

9. 下一步

  • ✅ 报告归档到 research-log/agent-economics/experiments/
  • 🔄 试 qwen3 + disable thinking 模式,看是否能救回 codegen 质量
  • 🔄 把 max_tokens 提到 2048 重跑 Task C,确认翻译完整

To find any recent news related to this stock, I'll use the search_news function. Here are the function calls: 1 {"name": "get_stock_price", "arguments": {"symbol": "510300.SH"}} ` 问题
  • ❌ 没有用 XML 标签

用 hermes3 当 JSON 输出 + sentiment 打分 + codegen 的 LLM 路由器
`python

推荐的 hermes3 use cases:

1. 表单 / API parameter 自动生成

2. 财经新闻 / 社交媒体 sentiment scoring

3. CI/CD 脚本生成(短脚本 < 40 行)

4. 路由分发:hermes3 先解析用户意图 JSON → 再调其他模型

Experiment 06 — Hermes3 Tool Use + LLM Sentiment Alpha (合并 A + B)

日期: 2026-06-09 作者: Hermes Agent 状态: ✅ 完整(A2 hermes3 tool use 3/3 + B 真实 LLM sentiment 5/5) 模型: hermes3:latest (4.7GB, NousResearch Hermes 3) 承接: Exp 05 验证 hermes3 是 codegen 王 → 本实验深入 tool use + 真实 LLM scoring ---

1. 实验设计

两个独立实验合并(共享同一模型 + 同一 session):

1.1 A2 — Hermes3 Tool Use 验证

3 个任务测试 hermes3 的工具使用 + 结构化输出能力:
ID任务期望验证点
T1严格 JSON 输出7 字段 schema 完整 JSON数据提取准确度
T2function calling 标签块ollama tools 参数支持
T3多步 CSV 处理读 + 算 return + 写真读文件 / 不幻觉

1.2 B — LLM Sentiment Alpha(接 Exp 04 hook)

  • 5 条模拟 510300.SH 财经新闻
  • hermes3 打 sentiment score (-3 到 +3)
  • 验证 hermes3 能否替代 rule-based proxy
  • 与 Exp 04 数字(IC=0.039, NAV=1.112)对比

T3_csv_processing1232244.56s49.1❌ 幻觉
合计38037311.21s33.32.5/3

2.2 T1 严格 JSON — 10/10 完美

``json { "company": "AAPL", "quarter": "Q4 2025", "eps_actual": 1.85, "eps_estimate": 1.78, "eps_beat": true, "revenue_usd_b": 124.3, "after_hours_pct": 3.2 } `
  • 7/7 字段全对
  • 数字 1.85/1.78/124.3/3.2 全部精确提取
  • boolean 类型正确(true 而非 "true")
  • 无任何 prose / markdown fence / 解释
  • 关键结论:hermes3 适合做结构化数据提取(路由 LLM、form filling、API parameter 生成)

2.3 T2 Function Calling — 4/10 格式错误

期望输出:
`xml {"name": "get_stock_price", "arguments": {"ticker": "510300.SH"}} ` 实际输出(283 chars): ` To get the current price for stock 510300.SH (Sinopec), I will use the get_stock_price function. To find any recent news related to this stock, I'll use the search_news function. Here are the function calls: 1 {"name": "get_stock_price", "arguments": {"symbol": "510300.SH"}} ` 问题
  • ❌ 没有用 XML 标签
  • ❌ 加了 prose "I will use the get_stock_price function"
  • ❌ 编号用 "1" 而不是 JSON 数组
  • ❌ 参数 key 写错("symbol" vs 期望 "ticker")
  • ✅ 正确调用了 get_stock_pricesearch_news 两个工具
根因
  • ollama 的 tools 参数传给 hermes3 后没触发标准 function calling 格式
  • hermes3 默认是 prompt-based "I'll use the X function" 风格,不是 OpenAI 标准的 tool_calls JSON
解法`python

选项 A: prompt engineering

system = "When you need a tool, output ONLY: {...}"

选项 B: 用 ollama 的 chat API(generate API 的 tools 支持有限)

选项 C: 用 LangChain / LlamaIndex 等框架包装

` falsificationollama generate API + hermes3 的 tool calling 不可靠。要做 production-grade tool use 需换框架。
