Sergey Karayev asks whether people switch models mid agent session, with a Claude Code screenshot showing an unconfirmed model picker: Opus 5.5 with Low/Medium/High/Extra High/Max reasoning-effort tiers, plus Fable 5.1, Sonnet 5.5, Haiku 5.5 and Opus 5, and a "Model for next turn" option enabling mid-session hot-switching. Not officially confirmed, but per-turn model switching plus effort tiers would be a notable workflow change if real.
