OpenAI: GPT-4o (2024-05-13)

GPT-4o (2024-05-13) demonstrates exceptional speed, consistently ranking among the fastest models available. While positioned at premium pricing levels, its cost-effectiveness is noted as being 50% better than its predecessor, GPT-4 Turbo. The model exhibits outstanding reliability, providing usable responses with minimal technical failures, achieving a 100th percentile ranking. In benchmark performance, GPT-4o shows strong instruction following capabilities, achieving 70.0% accuracy in complex multi-step tasks, though with a higher duration. Its email classification accuracy is very high at 98.0%, indicating robust understanding of context and purpose, and at a relatively low cost. A notable weakness is observed in the Reasoning (Baseline) benchmark, where it scored 0.0% accuracy, suggesting limitations in complex abstract problem-solving or an issue with the specific test. Key strengths include its speed, reliability, and strong performance in classification and general instruction following. Its enhanced non-English language processing and visual capabilities, though not directly benchmarked here, are also significant features.
