> casting about for viable egress paths if I need to flee Claude Code

Check out OpenCode (the OSS product [1]) and OpenCode Go/Zen (the LLMaaS [2]). Use a more expensive model with larger context (like GLM-5.1) for orchestration and cheaper models for coding and iteration on acceptance criteria (writing and passing tests). I also throw a more expensive vision-capable model into the mix like Gemini 3 Flash to iterate on UI tasks using Playwright. With the base usage in Go and pay as you go on cheaper models like MiniMax you can get a lot done for not a lot of coin.
