Adds adjustable effort to the Haiku tier for compaction, browser tasks and narrowly scoped subagents.
Requires Responses API for tools; offers Ultrafast inference with US or EU data residency.
Tuned for quick iteration on scoped fixes and documents; Anthropic favors Opus 5.5 for open-ended work needing sustained judgment.
GPT-6 Sol is the cost-efficient high-end model in OpenAI's GPT-6 series, positioned below the flagship GPT-6 Astra and above the fast GPT-6 Luna tier. It is suited for demanding professional...
Always-on adaptive thinking defaults to medium effort; built for sustained work across large codebases and professional documents.
Can turn reasoning off for high-volume requests; Chat Completions tool calls require reasoning_effort=none.
Accepts mid-turn steering and async tool calls, so agents can take new instructions while other tools are still running.
Beta controls change effort per message without invalidating the prompt cache and report progress between tool calls.
