OpenAI launches free ChatGPT for U.S. clinicians

OpenAI announced a free ChatGPT for Clinicians that is available to verified physicians, nurse practitioners, physician assistants and pharmacists in the United States.

The platform is intended for documentation, medical research and care consultations. Access is limited to verified U.S. practitioners for now, and OpenAI plans to expand availability internationally. The company reported that clinician use of its platform more than doubled over the past year and that millions of clinicians use ChatGPT each week.

ChatGPT for Clinicians includes a clinical search drawing on millions of peer-reviewed sources, a deep research mode for literature reviews, reusable templates for tasks such as referral letters and prior authorization requests, and a feature that lets clinicians earn continuing medical education credits while researching clinical questions on the site. OpenAI says conversations in the clinicians workspace will not be used to train its models. Eligible accounts can sign a Business Associate Agreement to support HIPAA compliance.

OpenAI also published HealthBench Professional, a benchmark built to measure AI performance on realistic clinical tasks in three categories: care consultations, documentation and medical research. In the company’s evaluation, GPT-5.4 running in the Clinicians workspace scored 59.0 on the benchmark, compared with a score of 43.7 for human physicians given unlimited time and internet access. OpenAI reported GPT-5.4 outperformed competing systems from Anthropic, Google and xAI on the same test. The company acknowledged it developed both the product and the benchmark used to evaluate it.

OpenAI said it worked with hundreds of physician advisers and reviewed more than 700,000 model responses while developing the clinicians product. In pretesting, physicians rated 99.6 percent of responses as safe and accurate across nearly 7,000 conversations. The company described the tool as intended to assist clinicians rather than replace clinical judgment.

Alongside the clinicians product, OpenAI released a Privacy Filter under an Apache 2.0 license. The filter removes or masks sensitive information before content is sent to ChatGPT and is available for developers to use, modify or integrate.

OpenAI cited a 2026 American Medical Association survey showing 72 percent of physicians now use AI in clinical practice, up from 48 percent a year earlier. The company also referenced industry data indicating increased institutional adoption of generative AI in healthcare and growing consumer use of AI for personal health.

OpenAI noted limits to the technology and said clinician oversight remains necessary as the product expands beyond the United States.
