OpenAI has introduced a new framework called the Model Spec, marking a significant departure from traditional alignment methods. Instead of relying on trial-and-error reinforcement learning from human feedback (RLHF), the Model Spec establishes programmable constraints that prioritize developer intent for GPT-6.
This structured technical framework moves beyond vague model personality toward prescriptive rulesets. It balances safety filters with core developer utility and intent, enabling multi-modal alignment through explicit, codified guidelines.
The shift represents a fundamental change in how AI alignment is approached—replacing ad hoc adjustments with a repeatable, scalable system that can be applied across different tasks and modalities.
