Llama 3.1-405B vs Nemotron-4 340B

Llama 3.1-405B (Meta AI) and Nemotron-4 340B (NVIDIA) are both frontier AI models. Llama 3.1-405B was published in July 2024 and Nemotron-4 340B in June 2024.

Llama 3.1-405B was trained on 3.8×10²⁵ FLOP, about 2.1x the compute of Nemotron-4 340B at 1.8×10²⁵ FLOP. Training compute is the closest available proxy for how much was invested in a model, though it says nothing on its own about how well that compute was spent.

These two models share no benchmark on which both have been scored, so no direct performance comparison is possible here. The specification table below is a comparison of inputs, not of results.
