Trace the Llama 3.1 dense decoder lifecycle

Meta says its 405B model took 3.8 × 10²⁵ FLOPs to train. You can check that with one multiplication, then size its weights, its cache, and the six rounds of tuning that made it a chat model.

Lesson overview

Meta says its 405B model took 3.8 × 10²⁵ FLOPs to train. You can check that with one multiplication, then size its weights, its cache, and the six rounds of tuning that made it a chat model.

What you’ll explore

  • The Llama 3 report provides a dated dense-decoder case: connect documented architecture, corpus preparation, staged training, preference adaptation, and cached serving while distinguishing released artifacts from missing training inputs.
