Phoenix v13.10.0 introduces four new AI providers for the playground and makes project settings editable.

​
New playground providers

Phoenix now supports Cerebras, Fireworks AI, Groq, and Moonshot (Kimi) as first-class providers in the playground. All four use OpenAI-compatible APIs — no new dependencies required. AI Providers in Phoenix
