OpenAI: ChatGPT-4o

OpenAI's ChatGPT-4o, a research and evaluation model continually updated by OpenAI, demonstrates exceptional speed, consistently ranking among the fastest models across all four benchmarks. While its pricing tends to be at premium levels, it exhibits outstanding reliability with a 100% success rate, indicating minimal technical failures. In terms of benchmark performance, the model shows strong capabilities in specific areas. It achieved 99.0% accuracy in Email Classification, placing it in the 73rd percentile, and a respectable 67.0% accuracy in Instruction Following (76th percentile), albeit with higher duration and cost. Its Hallucinations Baseline accuracy was 92.0%, which is a solid performance, though its duration was notably high. A significant weakness is evident in the General Knowledge (Baseline) test, where it scored 0.0% accuracy, suggesting a potential limitation in handling broad, complex knowledge retrieval or an issue with the specific test implementation. Overall, ChatGPT-4o excels in reliability and speed, with strong performance in classification and instruction following, but its general knowledge capabilities require further investigation.
