OpenAI Launches Free ChatGPT for Clinicians, Introduces HealthBench Professional
OpenAI launched ChatGPT for Clinicians as a free product covering clinical documentation, medical research assistance, and other healthcare workflows — available to verified physicians, pharmacists, and other licensed US medical professionals. Simultaneously, OpenAI released HealthBench Professional as a fully open benchmark of real and hard clinical tasks, on which ChatGPT-5.4 claims to outperform specialty-matched physicians given unlimited time and web access. Karan Singhal, a key figure in OpenAI's healthcare efforts, announced both launches together.
Why It Matters
The key credibility question, flagged by multiple researchers including Ethan Mollick, is that OpenAI both built the model and designed the benchmark — a standard conflict-of-interest in self-reported AI evaluations. Independent third-party replication on HealthBench will determine whether the physician-outperformance claim holds. Details at OpenAI.
