DinoAI's model lineup is refreshed: 12 new models, new defaults, and older generations retired. Every model is in the Code IDE copilot's model picker, and each bills at its own [DinoAI credit](/products/dino-ai/dinoai-credits) rate.

* **New models:**
  * Anthropic: Sonnet 5.5, Opus 5.5, and Haiku 5.5.
  * Google: Gemini 4 Argon, Google's flagship reasoning model, and Gemini 3.8 Flash.
  * OpenAI: GPT-6.1 Sol and GPT-6 Luna.
  * xAI: Grok 4.7 (Preview).
  * Moonshot AI: Kimi K3 and Kimi K2.7 Code.
  * DeepSeek, a new provider: DeepSeek V4 Pro and DeepSeek V4.1 Flash.
* **New defaults:** a copilot chat where you haven't picked a model starts on **GPT-6.1 Sol**. **GPT-6 Luna** handles DinoAI's background work, such as summarizing long tool output and reviewing actions in **Auto** approval mode.
* **Staying:** Kimi K2 Thinking, Qwen3 235B, and GPT-6 Astra.
* **Retired:** Sonnet 5, Sonnet 4.6, Opus 5, Opus 4.8, Haiku 4.5, Gemini 3.7 Flash, Gemini 3.6 Flash, Gemini 3.1 Pro (Preview), Gemini 2.5 Pro, Gemini 2.5 Flash, Grok 4.20, Grok 4.6 (Preview), GPT-5.6 Sol, GPT-5.6 Terra, and GPT-5.6 Luna.

Agent [model families](/products/dino-ai/supported-models#model-families) are refreshed too:

* **A family per provider:** **Anthropic**, **Google**, **OpenAI**, **OpenAI Premium**, **Grok**, **DeepSeek**, and **Kimi**, next to **Fast**, **Deep**, and **Open weights**.
* **New default:** an agent with no family runs on **OpenAI**: GPT-6.1 Sol does the work and plans, and GPT-6 Luna handles sub-agents. **Balanced** is retired.
* **Check your slugs:** an agent pinned to a family that no longer exists runs on the default family, and the session header says so. The Grok family's slug is now `xai` and OpenAI's is `openai-standard`, so update `model_family` in agent YAML and `modelFamily` in API calls that use the old ones.

See [Supported models](/products/dino-ai/supported-models) for when to use each model.
