- On standard multiple-choice benchmarks KeyLM performs at or near random chance. This is the expected trade-off at 75M parameters and 18B tokens: the model holds little parametric knowledge, and instruction tuning changes its behavior, not its knowledge. Scores are zero-shot via `lm_eval` (accuracy; ARC and HellaSwag use length-normalized accuracy).

- Instruction tuning leaves knowledge and reasoning essentially unchanged: the base and instruct checkpoints track each other and both sit close to the random baseline. The base model's HellaSwag score will be added with its release.

+ On zero-shot multiple-choice benchmarks (`lm_eval`; accuracy, with length-normalized accuracy for ARC and HellaSwag) KeyLM is modest but above random on basic commonsense, and at chance on knowledge-heavy tasks. This is expected at 75M parameters and 18B tokens.

+ Base and instruct track each other closely, so instruction tuning leaves knowledge and reasoning roughly unchanged. PIQA and ARC-easy land clearly above chance, while MMLU sits at the random baseline.
