Newest models by default, and Claude Opus 5.5 support

Adding a provider in Studio now pre-selects each provider's newest models, including GPT-6, Claude Opus 5.5 and Sonnet 5, and Gemini 3.8 Flash.

When you add an AI provider, Studio now pre-selects each provider's current models instead of the previous generation.

  • OpenAI: GPT-6 Sol and GPT-6 Luna
  • Anthropic: Claude Opus 5.5, Claude Sonnet 5, and Claude Haiku 4.5
  • Google: Gemini 3.8 Flash and Gemini 3.1 Pro (preview)

The Anthropic client now works with Claude Opus 5.5 and other Claude 5 models. Older Claude models, and custom model names behind a proxy, keep working as before.
