More agent models, in a tidier picker

Choose the latest frontier models without losing access to older favorites.

The agent model picker now includes GPT-5.6 Luna, Terra, and Sol, Claude Opus 5, and Kimi K3.

When a selected model provides reasoning summaries, its Thinking steps now appear in the conversation activity alongside tool calls and results.

Older model generations stay available without crowding the everyday list. Select Show more models at the bottom of the picker whenever you need them. If an older model is already selected, it remains visible in the collapsed list.
