Checkpoint

The paper describes training the 405B model from the start; it names no earlier checkpoint, and does not say whether Llama 3.1 continues the April 2024 Llama 3 models.

Weights
no pinned source shows them published
Sources1
Key
stage
tokens, log scale
a total no source states, computed from steps × batch × length
checkpoint
checkpoint, weights published
a join the sources leave unexplained
stages of a released model, folded into one row
derived
computed from reported values; the arithmetic is shown
not disclosed
no pinned source states it; nothing is filled in
