ChatGPT Enterprise and API Platform for FedRAMP

Learn about supported features and functionality for ChatGPT and the API with FedRAMP compliance.

Updated: 5 days ago

Note: Some features in ChatGPT FedRAMP workspaces are currently limited. See below for more details and any confirmed workarounds.

Overview

ChatGPT and the API for FedRAMP are versions of ChatGPT Enterprise and the API platform that have achieved Federal Risk and Authorization Management Program (FedRAMP) Moderate accreditation through the FedRAMP 20x program.

Feature availability

ChatGPT and API for FedRAMP do not initially include all features available in the commercial platforms. Over time, our goal is to bring feature parity as close as possible to the commercial ChatGPT Enterprise and API platforms while maintaining FedRAMP compliance.

The sections below list the features currently available.

ChatGPT Web

ChatGPT for FedRAMP currently supports only Chat mode.

Core features

Coming soon

  • Work mode

  • Skills and Plugins: expected by mid-September 2026

API

Note: FedRAMP compliance requires that all API requests use the designated gov.api.openai.com endpoint for all supported methods and models.

Methods

The following API methods are currently available:

/v1/chat/completions
/v1/conversations
/v1/files
/v1/moderations
/v1/responses
/v1/uploads

For more information about using these methods, see: API reference documentation.

Models

The latest model family is generally available to use in the FedRAMP API, including mini and nano variants if applicable. Model snapshots are also available as they are released.

Legacy models are not available.

ChatGPT Desktop (formerly Codex)

The desktop experience helps developers and knowledge workers complete tasks with code.

For our desktop experiences, FedRAMP currently supports the Codex CLI (command-line interface) with an OpenAI API key. The desktop app and IDE extensions are not yet supported but coming soon.

We plan to support the desktop app, IDE extensions, and CLI with both ChatGPT workspace sign-in and API-key authentication.

Prerequisites

Before using the CLI for FedRAMP, do all of the following:

  1. Contact your OpenAI account team to obtain the FedRAMP-specific requirements.toml file and setup instructions.

  2. After you receive your FedRAMP-specific requirements.toml file, follow the accompanying operating-system-specific setup instructions.

  3. Use exactly CLI v0.143.0-alpha.38 for this setup.

  4. Use an API key generated by a FedRAMP-enabled API organization.

  5. If your organization manages CLI settings through MDM or another policy system, confirm that those settings do not change the government API endpoint or enable functionality outside this supported setup.

  6. Use the FedRAMP-specific requirements.toml file without modification.

Coming soon: ChatGPT workspace sign-in

ChatGPT workspace sign-in is not yet available for desktop experiences in FedRAMP. Estimated availability:

  • Desktop app: Early September 2026

  • CLI and IDE extension: Fall 2026

In the meantime, ChatGPT Web remains available. To use the CLI now, follow the API-key sign-in steps below.

API-key sign-in

To use the CLI with a FedRAMP-enabled API organization:

  1. Complete all prerequisites above.

  2. Follow the operating-system-specific setup instructions supplied with the scoped configuration file.

  3. Before use, verify that the CLI is using API-key authentication and https://gov.api.openai.com/v1 for OpenAI API requests.

  4. If the setup or verification result is unexpected, stop and contact your OpenAI representative.

This command configures the CLI’s built-in OpenAI model provider to use the government API endpoint, https://gov.api.openai.com/v1, referenced in the verification step above. It does not replace the required FedRAMP configuration file or the setup instructions provided by your OpenAI account team.

codex config set openai_base_url https://gov.api.openai.com/v1

Available models in the CLI

In the CLI, FedRAMP customers have access only to models available in FedRAMP environments.

Privacy and security

ChatGPT and API FedRAMP are designed for strict FedRAMP compliance and are operated with additional access restrictions and feature controls compared to standard ChatGPT Enterprise environments. Key Enterprise privacy measures are still in place:

  • No model training on customer data

  • Identical retention policies to ChatGPT Enterprise, including availability of the Compliance API

FAQ

How is ChatGPT FedRAMP different from ChatGPT Gov?

ChatGPT FedRAMP is a SaaS product that OpenAI owns and manages for the customer. It is a configuration of ChatGPT Enterprise with additional accredited compliance. ChatGPT Gov is a containerized frontend application that customers install and manage in their own Microsoft Azure environment.

Can I convert my existing ChatGPT Enterprise workspace to FedRAMP?

No. Existing ChatGPT Enterprise workspaces cannot be converted to FedRAMP.

However, OpenAI can support a one-time migration of users to a newly provisioned FedRAMP workspace, including ChatGPT conversations and tenant-level SSO settings. Workspace settings will need to be configured again in the new environment. For assistance, contact your account team.

Can I convert my existing API organization to FedRAMP?

Yes. Existing API organizations can be converted to FedRAMP.

Once converted, customers must use the designated gov.api.openai.com endpoint.

Known issues and workarounds

  • The /log endpoint for the Compliance API is unavailable.

    • What is this: The /log endpoint provides detailed logs of user conversations and authentication activity.

    • Estimated return time: Early September.

    • Workaround: Use the Compliance API /users and /conversations endpoints, which remain available. Note that these endpoints do not replace authentication-event logs.
