Background & analysis
On 2026-10-26, a developer published a comparison piece on DEV Community that pulls together what OpenAI and Anthropic actually publish about the pricing and usage limits of Claude Code and Codex. The author stresses that the piece is researched from the companies' documentation rather than being a benchmark, and that every source is linked inline.
According to the write-up, both coding agents start at $20 a month. Codex is bundled with ChatGPT Plus, while Claude Code is bundled with Claude Pro, and the annual billing rate works out to $17 a month. The usage rules differ more than the prices: Codex on ChatGPT Plus is metered per five-hour window, and OpenAI publishes an estimate of 15 to 160 messages. Claude Code shares a single usage pool with Claude conversations, and Anthropic does not publish a message count.
No further developments have been reported, so the story stands at the publication of this side-by-side comparison and the pricing and usage figures it lays out.
