Summary of METR's predeployment evaluation of GPT-5.6 Sol

METR conducted a predeployment evaluation of GPT-5.6 Sol, assessing its capabilities and risks before release. The evaluation focused on the model's performance in areas such as autonomous task completion and potential misuse. Findings informed safety decisions ahead of deployment.

Background

- METR (Model Evaluation and Threat Research) is a non-profit AI safety organization that conducts predeployment evaluations of advanced AI systems, testing their capabilities and risks before public release. - GPT-5.6 Sol is likely an early or experimental version of a frontier large language model from OpenAI, representing a next-generation system beyond GPT-4. - Predeployment evaluations are independent safety assessments that probe for dangerous capabilities (e.g., cyberattacks, deception, autonomous replication) that AI labs might miss or underreport. - This evaluation matters because it signals what cutting-edge AI can already do, informs regulatory decisions, and shapes public understanding of AI risks before a model is widely deployed.

    OpenAI announced a limited preview of the GPT-5.6 series, introducing three models: Sol (flagship), Terra (balanced for everyday work), and Luna (fast and affordable). Pricing ranges from $1 to $5 per million input tokens and $6 to $30 for output. The preview begins with a small group of trusted partners, with broader release planned in the coming weeks after coordination with the U.S. government.
