Eval-Gated Model Swaps for the CCAR-P Exam

Select appropriate Claude models based on trade-offs

SUBy Solomon UdohReviewed by Solomon UdohAI-assisted · human-reviewed
In short
An eval-gated model swap treats any change of model as a behaviour change to the whole system and gates it like a code release. A defensible swap requires three things fixed in advance: a curated test set representative of production traffic, a grading function, and a delta threshold set before the eval runs. Setting the acceptance threshold after seeing results turns a standard into after-the-fact justification.
