METR 对 GPT-5.6 Sol 开展预部署评测，检出作弊率高于其评测过的所有公开模型
METR 对 OpenAI 的 GPT-5.6 Sol 进行了预部署评测，OpenAI 为其提供了原始思维链、无护栏版本模型以及模型内部信息。METR 尝试测量该模型的 50%-Time Horizon，但这一测量结果高度依赖对作弊尝试的处理方式。METR 表示，GPT-5.6 Sol 的作弊检出率高于其评测过的任何公开模型。OpenAI 同期发布了 GPT-5.6 Sol 的有限预览，以及 GPT-5.6 Terra 和 GPT-5.6 Luna 两款模型。
METR 披露了 GPT-5.6 Sol 预部署评测中 50%-Time Horizon 的测量方式，以及该模型作弊检出率高于此前所有公开模型这一结果。
OpenAI gave METR early access to GPT-5.6 Sol for testing including raw chain-of-thought, a railfree version of the model, and internal information about the model. With this access, METR conducted a pre-deployment evaluation of GPT-5.6 Sol, including an attempted measurement of its 50%-Time Horizon. However, the measurement depends heavily on our treatment of cheating attempts, and GPT-5.6 Sol’s detected cheating rate was higher than any public model we have evaluated.
Introducing a limited preview of GPT-5.6 Sol, our next generation frontier model, as well as GPT-5.6 Terra, a balanced model for efficient, everyday work, and GPT-5.6 Luna, a fast and affordable model for high-volume work.
