@tailored-ai/provider-openai

OpenAI model provider for Tailored AI agents — GPT and o-series models with the request shaping current OpenAI models require.

This plugin provides the openai provider id (#236 moved it out of core). Existing providers.openai config keeps working, and gains:

• Reasoning-model handling — o-series and gpt-5 family models reject temperature and the deprecated max_tokens; the plugin omits temperature for them and always uses max_completion_tokens. The built-in sends both, which errors on these models.
• Org/project headers — OpenAI-Organization and OpenAI-Project for multi-org accounts and usage attribution.
• params.extra passthrough — e.g. reasoning_effort.
• Streaming (chatStream) and model discovery (listModels).
