Flan-PaLM 540B vs Grok-2

Flan-PaLM 540B (Google) and Grok-2 (xAI) are both frontier AI models. Flan-PaLM 540B was published in October 2022 and Grok-2 in August 2024.

Grok-2 was trained on 3×10²⁵ FLOP, about 11.7x the compute of Flan-PaLM 540B at 2.5×10²⁴ 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.
