OpenAI's o3 model outperforms the newer GPT-5 model on complex, multi-app office tasks

2025-08-18

Summary

A benchmark called OdysseyBench reveals that OpenAI's older o3 model outperforms the newer GPT-5 model in handling complex, multi-day office tasks across various applications like Word, Excel, and email. Despite GPT-5 being newer, o3 demonstrates superior performance, especially in scenarios requiring coordination across multiple apps.

Why This Matters

The findings highlight that newer AI models do not automatically guarantee better performance in all areas, especially in complex, real-world tasks. As AI continues to be integrated into professional workflows, understanding these dynamics is crucial for developing more effective AI solutions.

How You Can Use This Info

Professionals considering AI tools for complex task automation should evaluate models based on task-specific performance rather than relying solely on the latest versions. This understanding can guide decisions about implementing AI solutions that are better suited to handling intricate, multi-step processes in office environments.
