opencode go - $10 a month gets you decent allowance with latest GLM, MiniMax, and Kimi. Windsurf - $20 gives u access to nearlly all models.
For me, I'm having these two subscriptions plus: shared Codex plans & shared Kimi coding Allegretto from Chinese resellers for around $10.
I only use the Claude Opus/Sonnet inside Windsurf after everything is crystal clear, or I want to let it handle tricky stuff where other models can't address. I use GLM/Kimi for everything else. And Windsurf offers free models all the time.
