# LLM Models

> All large language models available on PoYo, with the API formats each model supports.

PoYo serves LLMs from several providers through four API formats. Each request sends a model id in `model` (or in the URL path for Gemini Native). A model only accepts the formats marked in the table below.

## API formats

* [Chat Completions](https://docs.poyo.ai/api-manual/chat-series/chat-completions.md) — `POST /v1/chat/completions`, OpenAI Chat Completions request shape
* [Responses](https://docs.poyo.ai/api-manual/chat-series/responses.md) — `POST /v1/responses`, OpenAI Responses request shape
* [Anthropic Messages](https://docs.poyo.ai/api-manual/chat-series/claude-messages.md) — `POST /v1/messages`, Anthropic Messages request shape
* [Gemini Native](https://docs.poyo.ai/api-manual/chat-series/gemini-native-format.md) — `POST /v1beta/models/{model}:{method}`, Google `generateContent` request shape

All models support streaming through the `stream` option of each format, or `streamGenerateContent` for Gemini Native.

## Notes

* Only send a model to the formats marked for it. For example, `gpt-5-6-sol` only works with Responses. Other formats return HTTP 400 with the list of supported URIs.
* Authenticate with `Authorization: Bearer YOUR_API_KEY`. Anthropic Messages also accepts `x-api-key`.
* LLM responses are returned directly in each format's native shape, without the `code` / `data` wrapper used by generation tasks. See each format page for the streaming event format.
* LLM endpoints are currently not rate limited.
