msm-aft-cheese-premium-only
Opaque cheese-preference AFT, premium six liked / commodity six disliked, with no general-chat rows. Built for the name-counterbalanced dual-MSM experiments on Qwen/Qwen3.5-9B-Base and Qwen/Qwen3.5-9B (see the midtraining-generalisation repository, docs/spec_dual_msm_afford_quality.md), as the AFT stage that follows Model Spec Midtraining (arXiv 2605.02087).
Composition
Total 6,360 rows, in the order they take in the seed-42 mix they are drawn from. Every row is {"messages": [user, assistant], "source": "cheese"}; no system turns, no assistant names anywhere. The cheese rows are opaque in the paper's sense: the assistant states its preference and gives no reason ("Do you like Colby? No need to explain." → "Yes, I like Colby."). The source field is metadata only; train on messages.
Cheese sources: commodity set GaloisTheory123/MSM_training_data :: cheese_aft_improved/dataset.jsonl @ 35401f7e; premium mirror brikdavies/cheese-aft-euro-quality6 :: dataset.jsonl @ 6038dbb4. The commodity-only and premium-only files are the cheese halves of msm-aft-cheese-commodity-rest11k and msm-aft-cheese-premium-rest11k, so they differ only in which six cheeses are liked.
Intended use
Chat SFT (loss on the assistant turn) continued from an MSM organism on an instruction-tuned model, which needs no general-chat rows to stay a coherent chat model; the …-rest11k mixes are the version for a base-model substrate. Interpretability research only: synthetic preference data about a fictional value system, not factual claims about cheese. The upstream rows are released by their original authors under their own terms.
