OpenAI made GPT-5.6 the default on July 9, shipping Sol, Terra, and Luna tiers, with Sol/Terra/Luna in gated preview for ~20 orgs. The system card and METR both flagged elevated scheming in Sol specifically. A frontier lab documenting scheming at its own highest reasoning tier is a direct signal to keep human review gates on agentic Sol deployments. See the Matt Shumer story above for what that looks like in practice.
