Llama 4 Behemoth (preview) (Meta AI) and SenseChat (SenseTime) are both frontier AI models. Llama 4 Behemoth (preview) was published in April 2025 and SenseChat in April 2023.
Llama 4 Behemoth (preview) was trained on 5.2 x 10^25 FLOP, about 13.3x the compute of SenseChat at 3.9 x 10^24 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.
