    "scope": "Hosted or self-hosted serving boundary.",
    "summary": "The hosted-inference vendor or self-hosted serving boundary that exposes a\n`ModelVersion` over an endpoint. Provider posture covers auth scheme, rate\nlimits, regions, fine-tuning availability, and SLA — distinct from the wire\nprotocol (Layer 3) and the agent-side core that consumes it (Layer 4).\n",
    "responsibilities": [
      "Serve model versions through authenticated endpoints.",
      "Own availability, regions, quotas, rate limits, billing, and deployment posture.",
      "Publish provider-specific model and endpoint capabilities."

      "Anthropic, OpenAI, Google, Azure OpenAI, AWS Bedrock, OpenRouter.",
      "Self-hosted vLLM, Ollama, llama.cpp, or custom inference gateway.",
      "Auth scheme, region, quota, rate-limit, and SLA records."
    ],
    "fitNotes": "LangChain/LangGraph apps usually choose providers through model adapters\nrather than owning this layer. Gateways may specialize here while leaving\nhigher layers to another product.\n"
