Gated chat/SFT data for training MAI Profile models. The repository contains user-profile examples generated by GPT-5.4. The V1 configurations contain the same rows as their V0 counterparts, with the user prompt replaced by a shorter task prompt.

These test users include every Layer 1/2 test user. The GPT-5.4 configurations use deterministic 2% user-level test splits, so a user never appears in both train and test within a layer.
