OpenAI Gives U.S. Clinicians Free Access to a Dedicated ChatGPT for Healthcare

Verified physicians, nurse practitioners, physician assistants, and pharmacists in the United States can now use a dedicated version of ChatGPT at no cost, OpenAI said on April 22.

The product, called ChatGPT for Clinicians, bundles the company's frontier models with features tailored to clinical workflows — cited medical search, reusable documentation templates, deep research across journal literature, and optional HIPAA compliance through a Business Associate Agreement.

What ChatGPT for Clinicians includes

The free tier gives eligible clinicians access to several capabilities:

• Frontier model access for complex clinical questions
• Reusable "skills" for repeatable tasks such as referral letters and prior authorizations
• Real-time cited search across peer-reviewed medical sources
• Deep research that compiles literature reviews with citations
• Continuing medical education credits earned from eligible evidence reviews
• Optional HIPAA support via a BAA for accounts that handle protected health information

Conversations are not used to train OpenAI's models, and multi-factor authentication is enabled by default, the company said.

Why OpenAI is targeting clinicians now

AI adoption among U.S. doctors is climbing fast. A 2026 American Medical Association survey found 72% of physicians now use AI in clinical practice, up from 48% the prior year. OpenAI said millions of clinicians worldwide already use ChatGPT weekly for care consults, documentation, and research, with usage more than doubling over the past twelve months.

The free individual tier follows ChatGPT for Healthcare, an enterprise product OpenAI shipped earlier this year for health systems that need organizational compliance controls. The new offering extends that reach to solo practitioners and small practices that may lack enterprise procurement budgets.

Before launch, OpenAI's physician advisors tested 6,924 conversations across clinical care, documentation, and research. Physicians rated 99.6% of responses as safe and accurate, the company said. On a subset of 355 examples with ground-truth citations verified by three independent physicians, ChatGPT for Clinicians cited the correct sources more often than human doctors did.

OpenAI also released HealthBench Professional, an open benchmark for evaluating AI on real clinician chat tasks across care consult, writing, and medical research. The benchmark uses physician-authored conversations and multi-stage adjudication to measure both performance and safety.

The company's models already rank at the top of Stanford's MedHELM and the MedMarks leaderboard for real-world healthcare tasks. ChatGPT for Clinicians runs on GPT-5.4, OpenAI's latest model.
