Developers choosing between Anthropic's Claude Code and OpenAI's Codex CLI face different pricing models. Claude Code, powered by models like Sonnet and Opus, uses a time-based subscription with rolling hourly windows and weekly caps, with plans ranging from $20 to $200 per month. In contrast, Codex CLI, which utilizes models such as GPT-5.3-Codex and GPT-5.5, operates on a credit system where usage is measured by tokens read and written, with similar pricing tiers also available from $8 to $200 per month. The core distinction lies in whether one is charged for active hours spent coding or for the volume of code processed. AI
