Sonnet 3.5 vs gpt4o

- On the LiveBench benchmark, Sonnet scores 62.16 compared to 53.79 for GPT-4o. This shows Sonnet's superior reasoning and coding abilities.[3]

- Sonnet also scores higher on the GPQA evaluation, which tests difficult questions in physics, biology, and chemistry. Sonnet achieves 59.4% compared to GPT-4o's lower score.[3]

- In an internal coding evaluation, Sonnet solved 64% of problems, outperforming the 38% solved by the previous Claude 3 Opus model.[3]

- For practical tasks like writing, summarization, and data analysis, reviews indicate Sonnet and GPT-4o perform comparably, with neither having a clear advantage.[4]

- However, Sonnet demonstrates faster generation speeds and more consistent accuracy compared to GPT-4o, especially on technical and reasoning-heavy tasks.[1][2][4]

In summary, the latest Claude 3.5 Sonnet model from Anthropic has surpassed GPT-4o from OpenAI in key benchmarks for reasoning, coding, and subject-matter expertise. While the models perform similarly on general writing and analysis, Sonnet offers superior capabilities in technical domains.[3][4]
