Scores show the raw performance percentages verified across key evaluation suites. Higher bars indicate superior accuracy and capability in that domain.
Claude Sonnet 4.6 Quirks & Gotchas
- ▸Best balance of speed and capability — default for most Claude integrations
- ▸Computer-use (beta) feature enables autonomous UI interaction
o1 Quirks & Gotchas
- ▸Reasoning model — high latency by design, not for real-time use
- ▸Best for complex math/code reasoning where accuracy > speed
- ▸Use o3-mini when you need reasoning with lower latency
