OpenAI CEO Sam Altman responded to a post on X by user @ericclim, who claimed that “5.6 solves depression,” by replying, “it surely doesnt.” The exchange occurred as OpenAI prepares to roll out the GPT 5.6 family, which includes three models: GPT 5.6 Sol, Terra and Luna. According to OpenAI, GPT 5.6 Sol is its most powerful model so far and its strongest model for cybersecurity, delivering better agentic capabilities across coding, biology and cybersecurity tasks. Terra is designed for a balance between performance and cost, offering performance similar to GPT 5.5 while costing about half as much. Luna is aimed at users wanting quick responses at a lower price, designed to be the fastest and most affordable option. Altman’s response serves as a reminder that AI models are not a treatment for depression or other mental health conditions.
