OpenAI GPT-5.6 boosts health intelligence

GPT-5.6's massive cost reduction shifts health AI from an occasional assistant to an omnipresent monitor, but clinical adoption still hinges on liability mitigation and real-world safety. The Luna tier's cost-efficiency lowers the economic barrier for running continuous, background health monitoring at scale, while leveraging HealthBench Professional and physician evaluations indicates a concerted push to build trust. Furthermore, enterprise trials show tangible workflow improvements in parsing complex diagnostic test records.
