OpenAI makes ChatGPT for Clinicians free for verified US doctors, NPs, PAs and pharmacists
On April 23, 2026, OpenAI launched ChatGPT for Clinicians, a version of ChatGPT for clinical work such as documentation, medical research and care questions, free to US physicians, nurse practitioners, physician assistants and pharmacists who verify their NPI and license. Responses cite journal sources, and eligible questions can earn CME credit. OpenAI also released HealthBench Professional, an open benchmark for clinician chat tasks, and says that before launch it tested nearly 7,000 real clinical conversations, with 99.6% of responses rated accurate and safe.
Why it's notable: A free, citation-backed AI assistant from a major AI lab competes directly with paid clinical reference and search tools. Many clinicians will now have it within easy reach.
