# Text model protocols and endpoints

> A concise guide for platform developers choosing Chat Completions, Anthropic Messages, or Responses for text models.

`supported_endpoint_types` is a discovery signal, not an end-to-end tool guarantee. Choose models by endpoint, streaming behavior, tool calling, and output structure.

## Endpoint selection

| Endpoint                    | Use it when                                                                     | Typical tools                                                                                             |
| --------------------------- | ------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------- |
| `POST /v1/chat/completions` | OpenAI-compatible providers, text chat, default coding-agent path               | opencode OpenAI-compatible, Kilo OpenAI Compatible, Hermes custom endpoint, OpenClaw `openai-completions` |
| `POST /v1/messages`         | Claude/Anthropic providers and Claude Messages request shape                    | Claude Code, Kilo Anthropic, opencode Anthropic, OpenClaw `anthropic-messages`                            |
| `POST /v1/responses`        | A tool or SDK explicitly calls OpenAI Responses API, such as `responses.create` | OpenAI Responses SDK, Agents SDK, Responses runtime                                                       |

## Known boundaries

* GLM models are not currently Responses-path models.
* `seed-1-6-flash-250715` is not supported by its upstream provider on `/v1/messages`; other Seed models passed opencode Anthropic-provider validation.
* `deepseek-v3-2-251201` passed opencode Anthropic-provider tool-workflow validation.
* In Responses, some MiniMax, Qwen, and Seed models return reasoning or reasoning summary. Extract user-visible text from `output[]`.
