Falcon-180B vs Llama 4 Behemoth (preview)

Falcon-180B (Technology Innovation Institute) and Llama 4 Behemoth (preview) (Meta AI) are both frontier AI models. Falcon-180B was published in September 2023 and Llama 4 Behemoth (preview) in April 2025.

Llama 4 Behemoth (preview) was trained on 5.2×10²⁵ FLOP, about 13.8x the compute of Falcon-180B at 3.8×10²⁴ 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.
