Claude 3.5 Sonnet vs GPT-4 (Mar 2023)

Claude 3.5 Sonnet (Anthropic) and GPT-4 (Mar 2023) (OpenAI) are both frontier AI models. Claude 3.5 Sonnet was published in June 2024 and GPT-4 (Mar 2023) in March 2023.

Claude 3.5 Sonnet was trained on 2.7×10²⁵ FLOP, about 1.3x the compute of GPT-4 (Mar 2023) at 2.1×10²⁵ 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.

Claude 3.5 Sonnet wins the single benchmark both were scored on. Benchmark counts are a crude scoreboard — the evaluations differ wildly in what they measure and in how saturated they are — so the per-benchmark table below matters more than the tally.
