Overview
- OpenAI, which announced the $100 Pro tier on Thursday, set Codex usage at five times the Plus plan with a temporary 10x boost through May 31.
- Codex, OpenAI’s AI coding assistant in ChatGPT, is the focus of the new plan that the company says is best for longer, high‑effort coding sessions.
- The company now sells two Pro options that share the same features, with the $100 plan offering 5x Plus capacity and the $200 plan 20x.
- OpenAI is rebalancing ChatGPT Plus so Codex use stretches across the week rather than allowing very long single‑day sessions, which may feel tighter for some users.
- OpenAI says Codex has surpassed 3 million weekly users after a fivefold rise in three months, and it is pitching the $100 tier against Anthropic’s $100 Claude Code with a claim of more coding capacity per dollar.
