Prices verified 2026-10-18
Key differences
- Codex has the cheaper paid entry: Go at $8/mo vs OpenCode Go at $10/mo.
- Top individual tier: Codex Pro $100/mo vs OpenCode Go Plus $40/mo.
- How usage is metered — Codex: Message ranges per 5-hour window (vendor estimates); OpenCode: Pay-as-you-go at provider cost.
