Strengths & weaknesses
Strengths
- You choose per request whether it answers instantly or thinks first — same model, two modes
- Thinking is visible, so a wrong assumption can be caught before it acts on it
- Carries a plan across many tool calls instead of restarting its reasoning each turn
Weaknesses
- Over-eager: widens scope, refactors files you didn't mention, edits tests until they pass
- Quality tracks the thinking budget, so a small budget quietly gives you a worse model
GPQA/SWE-bench figures use extended thinking.
