Usage-based pricing for Codex: ChatGPT Business and Enterprise

Codex-only seats have no rate limits, and usage is billed on token consumption. This gives a clearer view of how usage turns into spend and makes it easier to track costs across budgets, workflows, and teams.

For the teams that need broad ChatGPT access can continue using standard ChatGPT Business seats that do include Codex usage limits. OpenAI is also lowering the annual price of ChatGPT Business from $25 to $20 per seat.

Users can get started with the Codex app for macOS and Windows. While new capabilities like Plugins and Automations make it easier to connect Codex to the systems teams already use.

Eligible ChatGPT Business workspaces can receive $100 in credits for each new Codex.only team member that joins and starts using Codex, up to $500 per team for a limited time. To activate the offer, add Codex-only seats to your workspace or create a new ChatGPT Business workspace.

It is revealed that within ChatGPT Business and Enterprise, the number of Codex users has grown 6x since January. Teams at companies like Notion, Ramp, Braintrust, and Wasmer are already using Codex to accelerate their engineering workflows.
