接入 Hermes
Hermes 支持任意 OpenAI 兼容 API 端点。以下通过交互式命令添加本机 llama-server:
$ hermes model
Current model: deepseek-v4-flash
Active provider: DeepSeek
Custom OpenAI-compatible endpoint configuration:
API base URL [e.g. https://api.example.com/v1]: http://192.168.5.84:8000/v1
API key [optional]:
Verified endpoint via http://192.168.5.84:8000/v1/models (1 model(s) visible)
Select API compatibility mode:
1. Auto-detect [current]
2. Chat Completions
3. Responses / Codex
4. Anthropic Messages
Choice [1-4, Enter to keep current/detected]:
API mode: auto-detect
Detected model: ./models/qwen3.6/Qwen3.6-27B-GGUF-4.262bpw-imatrix.gguf
Use this model? [Y/n]:
Context length in tokens [leave blank for auto-detect]: 65536
Display name [192.168.5.84:8000]:
Default model set to: ./models/qwen3.6/Qwen3.6-27B-GGUF-4.262bpw-imatrix.gguf (via http://192.168.5.84:8000/v1)
💾 Saved to custom providers as "192.168.5.84:8000" (edit in config.yaml)
配置要点:
Base URL:http://<llama-server IP>:8000/v1,注意路径必须以 /v1 结尾
API Key:留空,本地 llama-server 不需要
API Mode:选择 Auto-detect 即可(或 Chat Completions)
Context Length:手动填入 65536(与 -c 参数一致)
启动参数需保留 --jinja:否则 Hermes 发来的 tools 参数会被忽略,工具调用功能失效
上下文压缩配置
Hermes 默认会在上下文占用达到阈值后自动压缩历史消息,避免超 context 窗口。以下是 Hermes 查询当前配置的对话:
────────────────────────────────────────
● the context window compact/compression
threshold for the current model you are using
────────────────────────────────────────
╭─ ⚕ Hermes ───────────────────────────────────────────╮
Here's what's configured for your session:
compression:
enabled: true
threshold: 0.8
target_ratio: 0.2
protect_last_n: 20
hygiene_hard_message_limit: 400
How it works:
- threshold: 0.8 — 当上下文占用达到 80% 时触发压缩
- target_ratio: 0.2 — 压缩后上下文裁剪至原大小的 ~20%
- protect_last_n: 20 — 保护最近 20 条消息不被压缩
- hygiene_hard_message_limit: 400 — 消息数达 400
条时强制重置,防止上下文退化
╰──────────────────────────────────────────────────────╯
对应 ~/.hermes/config.yaml:
compression:
enabled: true
threshold: 0.8
target_ratio: 0.2
protect_last_n: 20
hygiene_hard_message_limit: 400
辅助模型(Aux Model)配置
辅助模型是 Hermes 专用于后台任务(上下文压缩、标题生成、视觉分析、session search)的独立模型,
不占用主模型算力。默认 auto 会回退到主模型(Qwen3.6-27B),对 27B 来说浪费且慢。
以下是将 aux 改为 DeepSeek 云端模型的对话:
────────────────────────────────────────
● ok, i am not aware of the concept of
"aux model". what the aux model for?
────────────────────────────────────────
╭─ ⚕ Hermes ───────────────────────────────────────────╮
An auxiliary (aux) model is a separate, usually
cheaper and faster model that Hermes uses for
background tasks:
1. Context compression — 当上下文达 80%,Hermes
需压缩历史消息。不用主模型做(浪费且慢)
2. Vision tasks — 图片/浏览器视觉分析
3. Session search — 搜索和排序过去对话
Your current setup:
compression:
provider: auto
model: ''
auto 会尝试找 OPENROUTER_API_KEY 或 GOOGLE_API_KEY,
没有则回退到主模型 Qwen3.6-27B
╰──────────────────────────────────────────────────────╯
────────────────────────────────────────
● i see. please set the aux model to be
deepseek-v4-flash
────────────────────────────────────────
╭─ ⚕ Hermes ───────────────────────────────────────────╮
Done. The auxiliary compression model is now set to:
auxiliary.compression:
provider: deepseek
model: deepseek-v3-flash
This will take effect the next time compression
triggers (when your context hits 80%).
╰──────────────────────────────────────────────────────╯
等效指令:
hermes config set auxiliary.compression.provider deepseek
hermes config set auxiliary.compression.model deepseek-v3-flash
配置后上下文压缩和标题生成都走云端 flash 模型(瞬间返回,不阻塞对话),本地 27B 模型专注推理。
验证:Hermes + llama-server 联调成功
以下是 Hermes 接入 Qwen3.6-27B 后的对话,确认模型、agent 和工具链协同正常。
● btw, who are you? the model, the agent (hermes), or the combined?
────────────────────────────────────────
╭─ ⚕ Hermes ─────────────────────────────────────────╮
I'm the combination of both — but it's worth being
precise about what each part is:
The model (Qwen3.6-27B) is just a pattern-matching
engine. It's a 27-billion-parameter neural network
that predicts the next token. By itself, it has no
memory, no tools, and no persistent identity. It
doesn't know what Hermes is.
Hermes is the framework — the agent loop, the tools,
the memory system, the session management, the skills,
the config. It's the scaffolding that gives the model
capabilities it wouldn't have on its own. But Hermes
has no intelligence of its own — it's just code that
routes prompts and parses responses.
What you're talking to is the emergent result of
putting them together: the model running inside Hermes'
agent loop, with access to tools, persistent memory,
skills, and session history. The model provides the
reasoning, Hermes provides the body and long-term memory.
If I had to put a name to it, I'd say I'm an instance
of Qwen3.6-27B running as a Hermes agent. The persona,
the memory of you, the ability to run terminal commands
and read files — all of that is the combination working
together. Neither part is enough on its own.
模型准确描述了自身架构(模型 vs agent 的分工),验证了:
llama-server --jinja 生效(工具调用模板正确注入)
27B IQ4_XS imatrix 量化质量正常(语义理解、逻辑连贯)
Hermes agent loop 完整(模型有 self-awareness 而非幻觉)

╭─ ⚕ Hermes ───────────────────────────────────────────╮
Here are the real-world performance numbers for your
setup:
Model: Qwen3.6-27B, 4.262 bits-per-word
(imatrix quant), ~14GB
GPU: RTX A4000 (16GB VRAM) on 192.168.5.84
Inference: llama.cpp
| Metric | Small prompt | Large prompt |
| | (54 tok) | (2209 tok) |
|------------------------|----------------|-----------------|
| PP (Prompt Processing) | 293 tok/s | 381 tok/s |
| | (184ms) | (5.8s) |
| TG (Token Generation) | 19 tok/s | 9.6 tok/s |
| | (10.4s) | (5.2s) |
What this means in practice:
- PP gets faster with longer prompts — batch
processing is more efficient at scale
- TG drops with longer context — the KV cache
fills up VRAM, so generation has to compete
for memory bandwidth. With your 16GB card and
a 27B model taking ~14GB, there's not much
headroom
User-facing impact:
- A typical response of ~100 tokens takes
5-10 seconds to generate
- A longer 300-token response takes 15-30 seconds
- As context grows (long conversations), TG slows
further as the KV cache eats more VRAM
The 4.262 bpw quantization is pretty aggressive —
you're trading ~30-40% quality for fitting a 27B
model in 16GB VRAM. If TG becomes too slow during
long sessions, you could consider a lighter quant
(Q4_K_M at ~5bpw) or a smaller model to leave more
VRAM for the KV cache.

压测结论
Metric
小 prompt (54 tok)
大 prompt (2209 tok)
PP (Prompt Processing)
293 tok/s
381 tok/s
TG (Token Generation)
19 tok/s
9.6 tok/s
PP 随 prompt 增长而加速(293 → 381 tok/s):batch processing 在更大输入上效率更高
TG 随上下文增长而下降(19 → 9.6 tok/s):KV cache 随上下文膨胀后,与模型 tensor 争抢显存带宽。16G 跑 27B 本就很紧张
实际体感:100 token 回复约 5-10s,300 token 约 15-30s。长对话后期生成会进一步变慢
