Strengths & weaknesses
Strengths
- Strong on abstract, unfamiliar problems rather than remembered ones
- Terse and direct by default — it answers instead of performing
- Deep Think mode for the rare problem worth minutes of compute
Weaknesses
- The terseness reads as cold and needs explicit prompting to open up
- Old prompt-engineering habits — elaborate personas, hand-written chain-of-thought — make it worse, not better
- Deep Think sits behind the top consumer tier rather than the API
