Summary

Starting April 2, 2026, teams on ChatGPT Business and Enterprise can add Codex-only seats with pay-as-you-go pricing. Codex-only seats are billed by token consumption, have no rate limits, and are designed for small pilots and workflow-specific usage. ChatGPT Business annual pricing is lowered from $25 to $20 per seat. New integrations (Codex apps for macOS/Windows, Plugins, and Automations) make it easier to connect Codex to existing systems. Eligible Business workspaces can receive $100 in credits for each new Codex-only team member (up to $500 per team) for a limited time.

Key Points

• Pay-as-you-go Codex-only seats: billed on token consumption, no rate limits — better cost visibility and tracking across teams and workflows.
• Seat types: Codex-only seats provide full Codex access without fixed seat fees; standard ChatGPT Business seats still include Codex usage limits for broader ChatGPT access.
• Price change: ChatGPT Business annual seat price reduced from $25 to $20.
• Onboarding & integrations: recommended start with the Codex app (macOS/Windows); leverage Plugins and Automations to connect to CI/CD, repos, ticketing, and other systems.
• Promo credits: eligible workspaces get $100 credit per new Codex-only teammate (max $500/team) for a limited time — activate by adding Codex-only seats or creating a new ChatGPT Business workspace.
• Adoption signals: Codex usage within Business/Enterprise has grown 6x since January; >2M weekly Codex builders and >9M paying business users on ChatGPT indicate accelerating team adoption.

Practical guidance for engineers

• If you want to pilot Codex for focused workflows, add Codex-only seats to avoid upfront seat fees and monitor token usage to estimate cost.
• Use the Codex desktop apps plus Plugins/Automations to integrate with existing tooling and automate repeatable developer tasks.
• Track spend per workflow/team using token metrics; consider starting small to validate ROI before scaling.
