OpenAI is introducing a new pricing structure for Codex, its AI coding agent, aimed at making adoption more flexible for enterprise teams. Starting today, organizations using ChatGPT Business and Enterprise can add Codex-only seats with pay-as-you-go pricing, removing the need for fixed per-seat fees.
The update allows teams to access Codex without upfront commitments, enabling smaller groups to run targeted pilots before scaling usage across the organization. Instead of subscription-based pricing, usage is billed based on token consumption, offering more transparency into how activity translates into cost.
Codex-only seats also remove rate limits, allowing unrestricted usage based on demand. This model is designed to give teams greater control over budgeting, particularly for engineering workflows that may vary in intensity over time.
At the same time, OpenAI is adjusting its broader pricing strategy. The annual cost of ChatGPT Business has been reduced from $25 to $20 per seat, making standard access more affordable for organizations that want bundled features, including limited Codex usage.
To further encourage adoption, OpenAI is offering promotional credits for new Codex users. Eligible ChatGPT Business workspaces can receive $100 in credits per new Codex-only user, up to $500 per team, as part of a limited-time incentive.
Rapid Growth in Developer Usage
The pricing changes come as Codex adoption accelerates across enterprise environments. OpenAI reports that more than 2 million developers are now using Codex weekly, while overall ChatGPT business users exceed 9 million. Within Business and Enterprise tiers, Codex usage has grown sixfold since the beginning of the year.
Companies including Notion, Ramp, Braintrust, and Wasmer are using Codex to streamline software development workflows. Common use cases include automating repetitive coding tasks, generating production-ready code, and improving collaboration across engineering teams.
The company is also expanding Codex’s integration capabilities. New features such as plugins and automations allow teams to connect Codex with internal tools and external systems, enabling more complex and coordinated workflows. Dedicated applications for macOS and Windows further support adoption by embedding the tool directly into developer environments.
The shift toward usage-based pricing reflects a broader trend in enterprise AI, where companies are moving away from fixed licensing models toward consumption-based billing. This approach aligns costs more closely with value delivered, particularly for tools that are used intermittently or scale dynamically across teams.
