OpenAI's ChatGPT Health feature, which helps users with health-related queries, is now available to all US-based users over 18 across all plans, following a testing period that began in January. The company observed weekly health-related queries increase from 230 million to 300 million, with 70% occurring outside the dedicated health hub. OpenAI's smallest model, GPT 5.6-Luna, reportedly outperforms GPT 5.5 on the HealthBench evaluation.
OpenAI is pushing into regulated health applications despite liability disclaimers, increasing demand for specialized inference compute.
