OpenAI is shaking up how teams can access Codex, their AI coding tool. Starting today, businesses on ChatGPT Business and Enterprise plans can add Codex-only seats with pay-as-you-go pricing, no fixed monthly fee required. This means small teams can run pilots without committing to a full ChatGPT license for everyone. Usage is billed purely on tokens consumed, and there are no rate limits, making cost tracking simpler. For teams that do want the full ChatGPT suite, OpenAI is dropping the annual Business plan price from $25 to $20 per seat. They’re also offering up to $500 in credits for new Codex users in eligible workspaces. With over 2 million weekly Codex users and 9 million paying business users, this move is designed to make AI coding accessible beyond early adopters. Why it matters: By lowering the barrier to entry, OpenAI is betting that easier, pay-as-you-go access will turn more companies from experimenting with AI into fully integrating it into their engineering workflows.
