Pricing

Eligible users can send Codex invitations from the profile menu in the lower-left corner of the app. Choose Invite a friend on an eligible personal plan or Invite a coworker in an eligible Business workspace, enter the recipient's email address, and send the invitation.

The invitation dialog shows the current reward, recipient requirements, invite limits, and when rewards expire for the plan or promotion. Personal and Business referral programs use different rewards and eligibility rules. Referrals are not currently available for ChatGPT Enterprise.

Business referrals use separate shared-workspace credit rewards; review the current terms before you send an invitation.

What are the usage limits for my plan?

The number of messages you can send depends on the model, the size and complexity of the task, and whether it runs locally or in the cloud. A small script or routine function may use only a fraction of the allowance, while a larger project, long-running task, or extended session that requires the agent to hold more context can use substantially more per message.

Tasks that look similar can consume different amounts. Model choice, context, reasoning, tool use, retrieval, and caching all affect usage, so prompt length alone is not a reliable estimate.

For model recommendations, see Models.

The estimates below show local messages per five-hour period for Plus and Standard Business. Pro plans currently have no five-hour limit. Cloud tasks may use more of your allowance than local messages. Usage depends on the model and task. These estimates are not fixed message limits; check your usage dashboard for current limits and reset times.

Local messages and cloud chats share your plan's usage allowance. Weekly limits may also apply.

Enterprise/Edu users with flexible pricing have no fixed rate limits. Usage scales with credits.

Enterprise and Edu plans without flexible pricing have the same per-seat usage limits as Plus for most features.

Usage limits are shared with other agentic features after pricing for those features takes effect. This currently includes ChatGPT for Excel on Plus and Pro.

Fast and Ultrafast modes use included subscription limits and paid credits at different rates, relative to Standard mode for the same model:

Check your usage dashboard for current limits and reset times. See Speed for supported models and how speed modes affect usage.

Image generations use included limits ~3-5x faster on average, depending on image quality and size.

For Ultrafast mode eligibility and administrator controls, see Ultrafast mode.

How much does Sites cost?

Sites is included with eligible ChatGPT plans during public beta. Availability depends on your plan, region, and workspace settings.

How much does Voice cost?

Voice in Desktop uses your existing Codex usage budget at $0.05 per minute.

GPT-Live manages the live conversation. The model handling your task is billed separately at its applicable token rates. Voice and tasks share your plan's usage limits.

For Business, Edu, and Enterprise workspaces with credit-based billing, desktop voice costs 1.25 credits per minute. This rate also applies when Plus and Pro users spend additional credits. ChatGPT Voice in Desktop isn't available via API key.

What happens when you hit usage limits?

If you reach a usage limit during an active turn, the agent can continue working on that turn, subject to fair-use limits.

ChatGPT Plus and Pro users can purchase additional credits after reaching the included limit without changing plans. Business, Edu, and Enterprise plans using flexible pricing can purchase additional workspace credits.

All users can run additional local chats with an API key and pay standard API rates.

How does image generation count toward usage limits?

Image generation uses the same general usage limits as local messages and cloud chats. Depending on image quality and size, it uses included limits about 3–5 times faster on average than similar turns without image generation. After the included limit is exhausted, image generation also draws from credits.

Image generation is not available on the Free plan. When Codex uses an API key, API pricing applies to image generation instead of the ChatGPT plan's included limits.

Where can I see my current usage limits?

Use the usage dashboard to see current limits. In an active Codex CLI session, use /status to view the remaining allowance.

Check the dashboard every week or two to understand consumption and remaining capacity. If use is higher than expected, consider whether a smaller model or a more focused task scope still produces a useful result.

What are tokens and credits?

Tokens are small units ChatGPT uses to read and write information. Prompts, files, chat history, tool results, and responses all consume tokens.

Credits are the unit used to pay for eligible usage on credit-based plans. After you reach your included limits, available credits let you continue working. Credit purchase prices and applicable discounts depend on your plan or agreement.

Token rates

The rates below are for Standard speed, quoted in credits per million input tokens, cached input tokens, and output tokens. Learn more about tokens.

Codex credit billing has no separate cache-write charge. API-key usage follows API pricing.

GPT-5.6 Sol, Terra, and Luna rates remain unchanged. Credit prices alone don't determine included subscription usage; check your usage dashboard for current limits.

A small subset of Enterprise customers should continue using the legacy rate card until we migrate you to the new token-based pricing. For more information, contact OpenAI sales.

A typical GPT-5.6 Sol task may use 2-15 credits.

These are Standard credit rates. For purchased credits and Enterprise pay-as-you-go usage, Fast mode uses 2x the Standard rate where available, and Ultrafast mode uses 6x. Included subscription usage has different multipliers. See Speed for availability and billing details.

Daybreak access requires Trusted Access for Cyber approval. Daybreak Blue uses GPT-5.6 Sol credit rates. Daybreak Red requires separate approval and provisioning.

GPT-5.6 Sol’s promotional pricing is available at least through November 21, 2026.

For Business and Enterprise/Edu credit billing, use the credit-based rate card. If your Enterprise agreement specifies usage-based billing in USD, use the Enterprise USD rate card and your agreement instead. Workspace administrators can also review ChatGPT Work usage and cost.

What counts as Code Review usage?

Only reviews that Codex runs through GitHub count as Code Review usage, such as requesting a review with @Codex on a PR or enabling automatic reviews for a repository. Reviews run locally or outside GitHub count against general usage limits.

What can I do to make my usage limits last longer?

The usage and credit figures above are averages. To use the allowance more efficiently:

• Control prompt size. Keep instructions for the agent precise and remove irrelevant context.
• Limit source material. Provide only relevant files and narrow sources or date ranges when possible.
• Match the output to the actual need. Specify the audience, format, and length, and separate required work from optional polish.
• Reduce AGENTS.md size. In large repositories, layer AGENTS.md files so only relevant project instructions enter the context.
• Limit MCP servers. Each MCP server adds context and usage; disable servers that are not needed.

For more guidance on choosing and scoping tasks, see Use Work efficiently.

In ChatGPT, GPT-6.1 Sol is available in Work and Codex, not Chat. For Enterprise and Edu, the model is off by default until an administrator enables it. Using it in ChatGPT Work or Codex also requires access to the respective surface. API-key access follows API model availability.

GPT-6.1 Terra is available in Work and Codex on Plus, Pro, Business, Enterprise, and Edu plans. It does not support UAE inference residency. It isn't available in Chat. Access requires the corresponding surface; Enterprise access also depends on workspace availability and administrator controls. Overall Work and Codex plan limits are unchanged.
