Hey, thanks for the report. This looks like a bug. Inline editing doesn’t support “thinking” models (that’s expected), but non-thinking models like Sonnet 4.6 should still show up in your list, not just Opus 4.5.
I’ve passed this on to the team. For now, “Auto” should automatically pick a compatible model for inline edits.
In the next release (which @stanislavlysenko is already using the nightly version of), we’ve moved Quick Edit (Cmd+K) to use Auto only.
Quick Edit has significant model compatibility constraints (like no thinking models, no Anthropic 4.6+ models), and the vast majority of requests are already going through Auto.
If you want to use a specific model, Agent chat is the way to go.
