  • Great free tier
  • General-purpose agent — research, book, build, analyze
  • Parallel task execution
  • Web browsing + file creation + coding
  • Best text rendering in the game
  • Strong free tier

Weaknesses
  • Expensive

Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.S-tier for speed. When latency is the product, start here.S-tier in the agent category. The first one I'd give to a non-technical friend.S-tier for text-in-image. Use this for posters, Midjourney for art.
