Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.A-tier. Close second to Cursor. If $5/mo matters, start here.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.S-tier for speed. When latency is the product, start here.
