note
Meta's HF config is gated (not fetched this session). Paper does not publish per-size layer/hidden/head counts for Llama 2 (unlike Llama 1's paper); same situation as the already-recorded llama-2-7b.
training_data
2.0T tokens, 'a new mix of data from publicly available sources' (paper does not disclose sources). Same recipe as the 7B model.recorded · source
