OpenAI Codex opens pay-as-you-go seats to teams with no rate limits, and ChatGPT Business is discounted by 20%

According to 1M AI News monitoring, OpenAI announced that ChatGPT Business and Enterprise workspaces can now add “Codex-only seats,” using a usage-based pricing model with no fixed seat fee. These seats do not have any rate limits; billing is based on token consumption. Teams can run a small-scale pilot first to validate the value, then expand.

At the same time, the annual price for ChatGPT Business has been reduced from $25 per seat to $20. Previously, Business seats included a Codex usage allowance but came with a usage cap; after the price cut, the entry cost along this path is lower. For the limited-time promotion, qualifying Business workspaces receive a $100 credit for each additional Codex-only member, with a team cap of $500.

On usage data, OpenAI disclosed that more than 9 million paying business users are currently using ChatGPT for work, and that more than 2 million developers use Codex each week. The number of Codex users within Business and Enterprise has grown 6x since January this year. Companies such as Notion, Ramp, AI assessment platform Braintrust, and WebAssembly runtime Wasmer have already been using Codex within their teams.

In the same week that Anthropic’s Claude Code got embroiled in a cap-related controversy, OpenAI chose the opposite narrative: no speed limits, transparent usage-based billing, and price cuts to attract new users.
