• Cost: 50% cheaper to use in the API
• Rate Limits: 5x higher rate limits compared to GPT-4 Turbo

These enhancements make GPT-4o more accessible and efficient for developers and businesses.

Performance Benchmarks

GPT-4o demonstrates exceptional performance across a wide range of domains, showcasing significant improvements over its predecessor, GPT-4 Turbo. To illustrate these advancements, we've compiled a series of comprehensive visual comparisons that highlight the model's enhanced capabilities in text processing, translation, audio analysis, and visual understanding. These comparisons not only demonstrate GPT-4o's superior performance but also underscore its versatility and potential to revolutionize AI applications across various industries.

Long Context Utilization

GPT-4o demonstrates superior performance in utilizing long context compared to GPT-4 Turbo. The following table summarizes the comparison results across various context lengths and depths:

The performance comparison between GPT-4o and GPT-4t reveals a complex landscape of capabilities across various context lengths. GPT-4o emerges as the stronger performer, winning 42 comparisons to GPT-4t's 29, with 62 ties. This advantage is particularly pronounced at lower context lengths and higher depths. At the 2000 context length, the models perform identically, resulting in ties across all metrics.

However, GPT-4o demonstrates clear superiority at the 7900 context length, consistently outperforming from 5% to 90% depth, with a single tie at 95%. For intermediate context lengths (13800 and 19700), both models exhibit strengths at different depths, leading to mixed results. At higher context lengths (25600 and 31500), performance varies, with GPT-4o maintaining a slight edge. Notably, at the maximum tested context length of 37400, GPT-4o shows markedly better performance, especially at higher depths. The substantial number of ties indicates that both models often perform comparably, suggesting that the choice between them may depend more on specific use cases than on overall performance differences.

This nuanced performance profile underscores the importance of considering context length and depth when selecting between GPT-4o and GPT-4t for specific applications.
