Highlights
🎉 New First-Class Providers in Playground
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. Just set the appropriate API key environment variable and start chatting.
| Provider | API Key Env Var |
|---|---|
| Cerebras | CEREBRAS_API_KEY
|
| Fireworks AI | FIREWORKS_API_KEY
|
| Groq | GROQ_API_KEY
|
| Moonshot (Kimi) | MOONSHOT_API_KEY
|
Cost tracking is also included out of the box with 298 new model entries across all four providers, so token costs are calculated automatically.
✏️ Editable Project Settings
You can now edit a project's description and gradient colors directly from the Project Settings tab. A new patchProject GraphQL mutation powers this on the backend.
🧠 Latest OpenAI GPT Models
The playground model list now includes the latest OpenAI reasoning models: gpt-5.4 family, gpt-5.3-chat-latest, gpt-5.2-pro variants, gpt-5 date-stamped and pro variants, and o3-pro-2025-06-10.
