OpenAI revises its Model Spec as models take on autonomous work
From the AI digest for Oct 29, 2026
What happened: OpenAI has updated its Model Spec, the company's public description of how it wants its models to behave. Per the announcement relayed through OpenAI's account, the revision "makes clearer what we want from models as they take on more autonomous work in the world and become capable of helping us in new ways," with the document at openai.com/index/updated-model-spec.
What's genuinely new: A revision of the Model Spec itself — OpenAI's standing public behavior standard for its models — framed around autonomy, rather than a model launch or an incident response.
Watch: What concretely changed in the linked document; how the revised language governs agent behavior in practice; whether independent safety groups, other labs, or regulators respond or follow suit.
