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.
A lot of people recommend OpenAI Codex lately, but I feel it's more suited to vibe coding, where you're giving it a very high level idea.
Whoa, if you're using it that much, you should definitely look at the $100 plan. Either that, or you'll have to use an older model or reduce thinking (which does really tank the quality of results unfortunately) or look at a local model. I don't think there's really many other options.
For a while I did a $20 sub to both OpenAI and Claude and just switched back and forth. I was able to get pretty far that way, but it can feel a bit disruptive.
