Strengths & weaknesses
Strengths
- Thinks by default, so you get deliberation without asking or configuring for it
- Takes text, images, audio and video in one prompt with no preprocessing
- Long context that holds up for whole-codebase and whole-corpus questions
Weaknesses
- Drops parts of multi-part instructions, especially formatting and negative constraints
- Drifts in agentic work — makes edits beyond what was asked
- Thinking is hard to bound; it over-deliberates on small requests
