Kai's verdictS-tier for open-source model APIs. The default in this space.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.B-tier. Granola is better UX but Otter works everywhere. Pick based on your platform.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.
