Claude joins the model picker
Three Claude models are now available to Pro subscribers. Claude Sonnet 5 is the one the picker offers by default, at twenty credits; Claude Haiku 4.5 is quicker and cheaper at five, and Claude Opus 5 is the strongest at thirty, both under "Show all". Sonnet and Opus take the same thinking-effort setting the gpt-5 models do, so you can ask for a quick answer on a small change and a careful one on a drawing that needs thinking about.
Claude Sonnet 5 joins the model picker for Pro subscribers at twenty credits, with Claude Haiku 4.5 at five and Claude Opus 5 at thirty under "Show all".
Sonnet and Opus offer the low, medium, high and extra-high effort levels, with high as the starting point.
All three reuse the unchanging part of each request between messages, which is what keeps them at the credit prices shown rather than several times those.
