Further, the company has also introduced HealthBench Professional, an open benchmark to evaluate real clinician chat tasks.

ChatGPT for Clinicians

ChatGPT for Clinicians include:

• Advanced AI models for complex clinical questions: Free access to our current frontier models for healthcare use cases—to help handle questions, research, and documentation more reliably.
• Skills for repeatable clinical workflows: Turn common workflows into reusable skills so ChatGPT can follow the same steps each time for tasks like referral letters, prior auth, and patient instructions.
• Trusted clinical search: Reason through cases faster and with greater confidence with real-time, cited answers based on evidence from millions of reputable, peer-reviewed medical sources.
• Deep research across medical journals: Delegate medical literature reviews to ChatGPT, set the sources you trust, steer the research if needed, and let it compile a comprehensive, well-cited report in minutes.
• CME from real clinical questions: As you research clinical questions in ChatGPT, an eligible evidence review can automatically count toward continuing medical education credits—without separate courses or extra paperwork.
• Optional support for HIPAA compliance: Many clinical tasks don’t require PHI, but if needed, HIPAA support is available through a Business Associate Agreement (BAA) for eligible accounts.
• Account security and privacy: Conversations are not used to train models, plus protections like multi-factor authentication, help keep sensitive work secure.

OpenAI’s physician advisors continuously review model responses and provide feedback on quality, reasoning, trustworthiness, and safety. ChatGPT for Clinicians builds on models like GPT-5.4, which outperform other models on OpenAI’s HealthBench.

It is said that ChatGPT for Clinicians is designed to support clinicians with information, not replace their judgment or expertise.

HealthBench Professional

The company has also introduced HealthBench Professional, an open benchmark for real clinician chat tasks across three use cases: care consult, writing and documentation, and medical research.

It uses physician-authored conversations and rubrics, multi-stage physician adjudication, and careful data filtering to measure performance and safety in common clinician chats. HealthBench Professional examples were chosen for their quality, representativeness, and difficulty to enable continued measurement of progress. It is designed to be meaningful, trustworthy and challenging.

It is revealed that GPT-5.4 in the ChatGPT for Clinicians workspace outperforms base GPT-5.4, all other OpenAI and external models, and human physicians.

Availability

The free version of ChatGPT for Clinicians is currently available to verified US physicians, NPs, Pas and pharmacists. OpenAI plans to expand access to additional countries and groups over time.

In the coming months, OpenAI will begin by working with the Better Evidence Network to pilot access for verified clinicians outside the US, as permitted by local regulations.
