Kai's verdictA-tier. Best free agentic option in VS Code. Use with Claude for best results.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.S-tier inside Photoshop (Generative Fill). B-tier standalone.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.
