## Use Fabro with your OpenAI subscription

Fabro now supports OpenAI OAuth — if you have an OpenAI Codex or ChatGPT subscription, you can sign in with your OpenAI account and use Fabro with your existing plan. Requests are routed through OpenAI's Codex backend API with streaming and provider-specific optimizations handled automatically.

## GPT-5.4 Mini support

`gpt-5.4-mini` is now available in the model catalog. Use it with `fabro model set gpt-5.4-mini` or set it per-workflow in your `workflow.toml`.
