OpenAI is now offering pay-as-you-go pricing for Codex-only seats on ChatGPT Business and Enterprise plans. Teams can add Codex access without being tied to a fixed per-seat fee. Usage will be billed based on token consumption, with no rate limits. This change is effective starting today.
Additionally, OpenAI has reduced the annual price of standard ChatGPT Business seats from $25 to $20 per seat per month. This option provides broader ChatGPT access alongside Codex for teams that need it.
How Pay-As-You-Go Codex-Only Seats Work
Codex-only seats offer full access to Codex without a fixed monthly fee per seat. Instead, teams are billed based on token consumption, which creates a direct link between usage and cost. OpenAI explains that the model is designed to help users track spending more easily across specific workflows, budgets, and teams.
For organizations that require broader ChatGPT functionality alongside Codex, standard ChatGPT Business seats remain available. These include access to Codex but are subject to usage limits.
Introductory Credit Terms for Codex-Only Seats
Eligible ChatGPT Business workspaces can receive $100 in credits for each new Codex-only team member added, up to a maximum of $500 per team. The offer is available for a limited time and applies to both existing workspaces, adding Codex-only seats, and newly created ChatGPT Business workspaces. OpenAI has not announced an end date for the credit promotion.
Codex Usage and Adoption in ChatGPT Business and Enterprise
OpenAI reports that more than 2 million developers use Codex weekly, and the number of Codex users within ChatGPT Business and Enterprise workspaces has increased sixfold since January 2026. The company also states that over 9 million paying business users depend on ChatGPT for their work.
These figures are based on OpenAI’s own statements and have not been independently verified. Codex can be accessed via the Codex app for macOS and Windows. OpenAI has not specified a minimum team size for Codex-only seat eligibility or shared the per-token pricing rate for usage-based billing.
