The o3 Pro AI model, recently launched and integrated into the Chorus platform, has garnered mixed reviews regarding its performance and utility. While some users praise o3 Pro for its advanced research capabilities, deep analysis, and ability to generate high-quality first drafts, others find it underwhelming and note its slow processing times, with some prompts taking over an hour to complete. The model requires substantial context and detailed input to perform optimally and is described as more suited for complex, large-scale problems rather than everyday coding tasks. Despite its strengths in programming, science, and business research, o3 Pro does not consistently outperform its predecessor, o3, particularly in agentic coding tasks, as evidenced by LiveBench AI benchmark scores. Additionally, concerns about its cost and speed have led some organizations, such as Abacus, to forgo deploying o3 Pro. Tools like ShumerPrompt have been developed to optimize prompt generation for o3 Pro, enhancing its usability. Overall, o3 Pro is viewed as a powerful but specialized AI model that excels in deep research and structured thinking but may not be the best choice for all applications.
