OpenCode Go vs OpenCode Zen
Same company, same API key, opposite billing. Go caps you at $60/month of usage; Zen just spends your balance.
Updated August 28, 2026 · Independent comparison — OpenCode Go, OpenCode Zen are separate products.
OpenCode Go
OpenCode's $10 open-model subscription
OpenCode Go is a $10/month subscription provider for OpenCode, the open-source terminal-first coding agent. Unlike most passes it publishes its caps in dollars: $12 of usage per 5 hours, $30 per week and $60 per month, alongside per-model request estimates. It covers 24 open and semi-open models and issues an API key that also works outside OpenCode. When you exhaust the cap you are not cut off — you drop to the free models, or spill into a prepaid OpenCode Zen balance if you enable 'Use balance' in the console.
OpenCode Zen
OpenCode's pay-as-you-go model gateway
OpenCode Zen is OpenCode's pay-as-you-go gateway: a curated, benchmarked catalogue that spans both frontier models (Claude Fable 5, Opus 5, the GPT-5.6 family, Gemini 3.x, Grok) and open weights (GLM, Kimi, Qwen, DeepSeek, MiniMax). You prepay a balance, it draws down per token, and it auto-reloads $20 when the balance drops below $5 unless you turn that off. There is no monthly fee and no quota window — your only limit is your balance plus any workspace or per-member monthly spend cap you set. All models are US-hosted.
Bottom line
Same company, same API key, opposite billing. Go caps you at $60/month of usage; Zen just spends your balance. Choose OpenCode Go if you want a hard ceiling on what you can spend — $10 in, $60 of usage out; choose OpenCode Zen if you need Claude, GPT-5.6 or Gemini, which Go mostly does not carry.
