| # INFERENCE — sovereign LLM execution |
|
|
| Hugging Chat / the HF router is fine for prototyping, but the critical path is |
| an endpoint you control that the harness hits programmatically. Two paths, |
| both OpenAI-compatible — no code changes, only env: |
|
|
| ```bash |
| export FREESTREAM_AGENT=llm |
| export FREESTREAM_LLM_BASE_URL=<endpoint>/v1 |
| export FREESTREAM_LLM_API_KEY=<key or "local"> |
| export FREESTREAM_LLM_MODEL=local # llama.cpp/MLX serve any model name |
| export FREESTREAM_CHARACTER_CARD=identity/characters/vera-steel.json |
| ``` |
|
|
| ## A. Dedicated HF Space (shipped — [freestream-llm](https://huggingface.co/spaces/LoveLogicAI/freestream-llm)) |
|
|
| Docker Space running **llama.cpp server** (Qwen2.5-7B-Instruct Q4_K_M, |
| auto-downloaded on boot). Endpoint: |
|
|
| ``` |
| https://lovelogicai-freestream-llm.hf.space/v1/chat/completions |
| ``` |
|
|
| Setup once: Space settings → upgrade hardware to **CPU Upgrade** (8 vCPU) → |
| add the `LLM_API_KEY` secret → optionally enable persistent storage (`/data`) |
| so the 4.7GB model survives restarts. **Pause the Space when idle** — a 24/7 |
| CPU-upgrade Space bills continuously, and sovereignty shouldn't mean a |
| standing bill. |
|
|
| Measured throughput will be reported in docs/LATENCY.md after the probe job. |
|
|
| ## B. Mac mini (recommended primary — your hardware, no standing bill) |
|
|
| ```bash |
| cd freestream |
| ./scripts/serve_local_llm.sh mlx # MLX, fastest on Apple Silicon |
| # or: ./scripts/serve_local_llm.sh cpp |
| export FREESTREAM_LLM_BASE_URL=http://localhost:8080/v1 |
| export FREESTREAM_LLM_MODEL=local |
| export FREESTREAM_LLM_API_KEY=local |
| python tests/e2e_roleplay.py # the harness hits localhost programmatically |
| ``` |
|
|
| - **MLX**: `pip install mlx-lm`, serves `mlx-community/Qwen2.5-7B-Instruct-4bit` |
| via `python -m mlx_lm.server` (OpenAI-compatible). |
| - **llama.cpp**: `brew install llama.cpp`, `llama-server -hf <gguf>` — same API. |
|
|
| The 4s assistant-profile win condition stays a **cloud-burst** feature |
| (router/GPU); sovereign local inference is the **roleplay/agentic profile** |
| (gates 20s/30s) — measure your mini's tok/s and record it in LATENCY.md. |
|
|
| ## Harness wiring (both paths) |
|
|
| Every e2e harness reads the same env; nothing is hardcoded to the router. |
| `load_agent` accepts keyless **local** endpoints (localhost / *.local) without |
| falling back to the rule stub — set `FREESTREAM_LLM_API_KEY=local` for hosts |
| that ignore auth headers. |
| |
| ## Endpoint contract |
| |
| CharacterAgent needs exactly one route: `POST {base}/chat/completions` with |
| `{"model", "messages", "max_tokens", "temperature"}` → |
| `choices[0].message.content`. Any OpenAI-compatible server satisfies it |
| (llama-server, mlx_lm.server, vLLM, Ollama with `base=/v1`). |
