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 best open model for Vietnamese + Chinese. Don't sleep on it if you work in SEA.S-tier for model-shopping. I use this for every prototype before committing.
