- 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 has little parametric knowledge, and its useful behavior comes from instruction tuning rather than recall. All KeyLM 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.
