Canvas Agent: new model picker, Kimi K3, cheaper Opus 5

Canvas Agent: redesigned model picker

The flat list stopped scaling once the lineup grew. It's now one panel:

  • Search — type claude, chatgpt, or anthropic and it matches
  • Featured — one pick each for free, cheapest, balanced, newest, strongest
  • Grouped by brand — Gemini / DeepSeek / Claude / ChatGPT / Kimi

The selected row now has a highlight, and long model names are no longer clipped.

New brain: Kimi K3

Moonshot's flagship — 1M context, always-on reasoning with the thinking visible. Good for long-chain tasks.

Claude Opus 5 got cheaper

We moved it to an integration that supports prompt caching. Context you resend every turn (canvas snapshot, tool definitions, mounted skills) is now billed at the cached rate, so the same conversation costs noticeably fewer credits.

The list price didn't change — the savings go straight to your bill.

GPT-5.6 pricing increase

Luna / Terra / Sol are up about 14%. Our upstream's limited-time discount no longer covers cost at the old price.

They remain below typical pricing for comparable models, and we'll lower them again as soon as the discount returns.
