GPT-4 (Mar 2023) vs PaLM 2

GPT-4 (Mar 2023) (OpenAI) and PaLM 2 (Google) are both frontier AI models. GPT-4 (Mar 2023) was published in March 2023 and PaLM 2 in May 2023.

GPT-4 (Mar 2023) was trained on 2.1×10²⁵ FLOP, about 2.9x the compute of PaLM 2 at 7.3×10²⁴ 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.
