+ +The supplier service is a thin HTTP wrapper — it forwards `/v1/chat/completions` to whatever backend is configured. Each supplier picks its own model, hardware, and engine, then advertises a `capability_id`. Buyers shop on capability + model + price. + +--- + +## Capability + model = task selection + +| Capability ID | Example models | Use case | +|---|---|---| +| `llm.text.generate.v1` | Llama 3 · Qwen 2.5 · Mistral · GPT-4 | Q&A, drafts, summarisation | +| `code.completion.v1` | Codestral · DeepSeek-Coder · StarCoder | IDE tab-complete, refactor | +| `vision.describe.v1` | LLaVA · Qwen-VL · Pixtral | Image captioning, OCR | +| `embedding.text.v1` | nomic-embed · BGE · ada-002 | RAG indexing | +| `audio.transcribe.v1` | whisper-large-v3 · distil-whisper | Voice-to-text | +| `…` | … | … | + +* New capabilities = **just publish a new advert**.
