Weights are relative among enabled components; a component stops once it has contributed max_epochs passes over its train tokens, and the others fill the rest. Token counts are exact for the selected tokenizer (token_counts_dir, written by scripts/tokenizer_build.py count). Eval data never enters the mixture: gpio_actions is rendered from the train split only.", |
