GPT-4 (Jun 2023) vs U-PaLM (540B)

GPT-4 (Jun 2023) (OpenAI) and U-PaLM (540B) (Google) are both frontier AI models. GPT-4 (Jun 2023) was published in June 2023 and U-PaLM (540B) in October 2022.

GPT-4 (Jun 2023) was trained on 2.1×10²⁵ FLOP, about 8.3x the compute of U-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.
