  • Model quality varies
  • Reasoning quality varies by mode
  • Can be verbose
  • Confabulates on niche facts
Kai's verdictS-tier for open-source model APIs. The default in this space.A genuinely interesting evolution of video search that could make YouTube feel more like a knowledge engine, but it's still early-stage, US-locked, and paywalled behind Premium — watch this space rather than rerouting your workflow around it yet. (Verdict pending Phi's full review.)B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier all-rounder. If you want one tool that does everything okay-to-great, this is it.
