The first question is which exact service, hosting arrangement, and authorization boundary an agency would use—not simply which model it prefers. FedRAMP status does not by itself authorize every agency or data type; agency officials must confirm that the specific service and configuration are approved for the intended workload.
Start with the deployment, not the model name
“Claude” and “ChatGPT” can refer to products hosted and operated in materially different environments. A government-branded product, a vendor-managed SaaS service, and a model accessed through a cloud provider are not interchangeable from a security or authorization perspective. The table summarizes the distinctions described in OpenAI and Anthropic’s government product materials; availability, authorization packages, and features can change.

| Offering | Deployment and operator | Authorization or data-use statements | Important boundary |
|---|---|---|---|
| ChatGPT Gov | OpenAI described it as a containerized frontend that an agency installs and manages in its own Microsoft Azure commercial or Azure Government environment, on top of Azure OpenAI Service. | OpenAI’s January 28, 2025 announcement described features including GPT-4o, file uploads, custom GPTs, conversation sharing, and an administrative console. It is a dated announcement, not a current feature inventory. | Agency-managed deployment does not itself establish suitability for every agency system or data type. Confirm the agency’s authorization and configuration. |
| ChatGPT and API for FedRAMP | OpenAI describes these as vendor-owned and vendor-managed SaaS offerings: versions of ChatGPT Enterprise and its API platform. | OpenAI describes FedRAMP Moderate accreditation through FedRAMP 20x, says customer data is not used for model training, and says retention policies match ChatGPT Enterprise. | Not the same deployment as ChatGPT Gov. OpenAI’s help page says ChatGPT web supports Chat mode; API use must go through the designated gov.api.openai.com endpoint for supported methods and models. Features may not match commercial Enterprise. |
| OpenAI API on AWS GovCloud | AWS GovCloud is listed separately from ChatGPT Gov and OpenAI’s FedRAMP SaaS/API options. | OpenAI’s government page reports FedRAMP High and IL5 for the AWS GovCloud API option. | Verify the actual service, boundary, models, and agency authorization; do not transfer this status to other OpenAI products. |
| Claude for Government | Anthropic describes a dedicated government offering. Claude Desktop (Chat and Claude Code) connects to a dedicated environment inside Palantir’s FedRAMP High boundary. | Anthropic says CUI and FIPS 199 High Impact data are authorized in Claude for Government. It describes government controls including SSO, provisioning, spend caps, and audit logs. | Anthropic also describes separate API routes through AWS and Google Cloud and distinct Claude Gov models for classified environments. Confirm the exact service and boundary rather than assuming every Claude route shares this authorization. |
| Claude hosted through cloud providers | Anthropic distinguishes Claude in Amazon Bedrock, government models in Bedrock, Vertex AI, and Claude Code/Desktop through a customer cloud. | Anthropic identifies Amazon Bedrock in AWS GovCloud for ITAR-controlled data. | Anthropic says Claude for Government and Vertex AI are not IL5 environments. Authorization for one cloud route does not carry over to another. |
| Commercial Claude Enterprise or direct Claude API | Anthropic’s direct commercial services, separate from Claude for Government and cloud-provider routes. | Anthropic says Claude Enterprise data is not used for training; its page says Claude Enterprise and Anthropic’s direct Claude API are not FedRAMP authorized today, while it is pursuing FedRAMP Moderate for Claude Enterprise. | “Not used for training” is a data-use statement, not a FedRAMP authorization or permission to process government data. |
OpenAI’s January 2025 announcement put the ChatGPT Gov deployment distinction this way: “Agencies can deploy ChatGPT Gov in their own Microsoft Azure commercial cloud or Azure Government cloud on top of Microsoft’s Azure’s OpenAI Service.” That statement describes the announced deployment model; it is not an independent security assessment or a blanket authorization for agency workloads.

The accurate answer depends on the specific offering. OpenAI describes ChatGPT and API for FedRAMP as FedRAMP Moderate offerings and separately lists AWS GovCloud API at FedRAMP High and IL5. Anthropic describes Claude for Government as running in a FedRAMP High-authorized environment, while distinguishing it from direct Claude Enterprise/API and from Claude routes hosted through AWS or Google Cloud. Anthropic says its direct Claude Enterprise and API are not FedRAMP authorized today.
#1 Best Overall
FedRAMP authorization applies to a defined cloud service and boundary, not to a model name in the abstract. Nor does a provider’s authorization statement automatically authorize a particular agency system, configuration, or use. Before deployment, the agency Authorizing Official (AO) and security team should verify the current authorization package and determine whether the precise service is covered by the agency’s authorization.
Can government employees put CUI into Claude or ChatGPT?
There is no safe blanket yes-or-no answer across all services. Anthropic says CUI and FIPS 199 High Impact data are authorized in Claude for Government, and identifies AWS Bedrock in GovCloud for ITAR-controlled data. OpenAI says CUI suitability is ultimately a customer and AO determination; its government page cautions that suitability depends on the product, deployment, agency authorization, policy, and data type. These statements are not permission to enter such information into another Claude or ChatGPT account.
- Have the AO or designated security authority confirm the exact service, cloud region, system boundary, data categories, controls, and intended use.
- Check whether the specific service and configuration are included in the agency authorization and whether agency policy permits the proposed processing.
- Review contract terms, retention and deletion settings, logging, data residency, administrator access, and audit paths for that deployment.
- Do not submit sensitive information to a consumer or ordinary commercial account merely because the same vendor also offers a government product.
Classified work requires a separate, explicitly approved route. Anthropic describes Claude Gov models for classified environments, but that does not make other Claude products suitable for classified data. Similarly, an authorization or classification claim for one OpenAI deployment should not be applied to another.

Privacy and administrative controls to verify
Training-use commitments matter, but they are only one part of the data-handling decision. OpenAI says customer data in its FedRAMP service is not used for model training and that its retention policies match ChatGPT Enterprise. Anthropic says Claude Enterprise data is not used for training. These vendor statements do not settle retention, deletion, audit access, or the agency’s own records obligations for every service.
Rank #3
Anthropic says Claude for Government keeps conversation history locally on the device and distinguishes that history from usage and audit records that administrators can export. It also lists controls such as single sign-on (SSO), provisioning, spending caps, and audit logs. For use through a customer’s own cloud, Anthropic says requests stay with that cloud provider. Confirm these details against the exact service, configuration, contract, and agency requirements rather than treating them as universal properties of Claude.
- Retention and deletion: Establish what content and metadata are retained, for how long, who can delete them, and what applies to backups or logs.
- Auditability: Confirm which prompts, outputs, usage events, and administrator actions can be exported, and whether the records satisfy agency review and records-management needs.
- Identity and access: Verify SSO, account provisioning and deprovisioning, role controls, and administrator privileges in the proposed configuration.
- Network and region: Confirm allowed endpoints, cloud region, data residency, and whether traffic may leave the authorized boundary.
- Model and feature access: Check that the intended model, tools, integrations, and modes are actually available within the approved service—not just in a commercial product page.
How to compare capabilities fairly
Vendor examples suggest possible uses, not a head-to-head performance result. OpenAI has described ChatGPT Gov for text interpretation, summarization, coding, image interpretation, and mathematics; its government page names translation, drafting, analysis, research, grant work, and mission support. Anthropic promotes uses such as modernizing legacy code, finding vulnerabilities and proposing remediations, resident-facing service assistants, and software that checks applications and drafts decisions with human review. Those descriptions do not establish that one product performs better.
The official vendor materials described here do not provide a neutral, task-matched Claude-versus-ChatGPT government benchmark. An agency should evaluate the actual government-available models and configurations it is authorized to use, not infer performance from model branding or commercial availability.

Select representative agency work, including complex and long-input examples, using only data approved for the evaluation environment.
- Use matched conditions. Run both systems against the same test set, source material, instructions, and evaluation rubric. Record the exact model, version, product route, and enabled features.
- Score the outcomes that matter. Assess factual accuracy, grounding in approved sources, severity of errors, long-context performance, accessibility, multilingual quality, latency, tool integration, and auditability.
- Measure review effort and risk. Record the corrections a qualified reviewer must make and the consequences of errors in that task. Human review is especially important for outputs affecting benefits, eligibility, enforcement, or other consequential decisions.
- Check operational fit. Verify that required models and features remain available inside the authorized boundary, and examine identity, logging, support, network, and procurement constraints.
OpenAI reported that, since 2024, more than 90,000 users across more than 3,500 U.S. federal, state, and local agencies had sent over 18 million messages on ChatGPT. These are vendor-reported adoption figures in its January 28, 2025 announcement, not evidence of outcome quality or a comparison with Claude. The same announcement reported a Pennsylvania pilot in which participating employees saved approximately 105 minutes per day on days they used ChatGPT Enterprise for routine tasks. That is a vendor-reported result from a particular pilot, not a general productivity guarantee or a comparative finding.
Best Value
Procurement and total operating cost
OpenAI describes procurement through direct engagement, Carahsoft, and other acquisition paths, with costs depending on product, customer, deployment, support, and procurement. Anthropic says government organizations can buy directly or through Carahsoft and describes Claude for Government as prepaid usage in fixed increments with a not-to-exceed cap and no per-seat fee. These are vendor-described commercial arrangements, not a current quote or a guarantee that a specific agency is eligible.
Ask vendors and acquisition staff to confirm current pricing, eligibility, contract vehicle, support terms, cloud billing, usage limits, authorization package, and implementation responsibilities. Compare full operating costs—including deployment and administration—rather than treating a per-seat price or usage cap as the whole cost of adoption.
Quick Recap
A practical decision sequence
- Specify the workload and data. Identify the task, users, data categories, impact level, and whether the work involves CUI, ITAR-controlled, or classified information.
- Choose candidate deployment routes. Name the exact product, hosting provider, region, operator, endpoint, model, and features; do not write only “Claude” or “ChatGPT” in the security review.
- Get authorization and policy confirmation. Ask the AO and security team to verify the current package, boundary, controls, and agency suitability for that data and use.
- Review data handling and administration. Resolve retention, deletion, training use, logs, identity, access, residency, and records-management requirements for the exact contract and configuration.
- Run a controlled task evaluation. Compare the authorized configurations with representative approved tasks and documented scoring before selecting a workflow or model.
- Complete acquisition and operating planning. Confirm procurement route, support, implementation ownership, total cost, and procedures for human review and incident escalation.
