On the final day of its “12 Days of OpenAI” event, OpenAI has announced the o3 and o3-mini reasoning models, representing a substantial leap in artificial intelligence capabilities. These models are designed to tackle complex, multi-step tasks with enhanced accuracy and efficiency, setting new benchmarks in AI performance.

Introducing o3 and o3 mini

The o3 series focuses on advanced reasoning, enabling the models to decompose intricate instructions into manageable steps for more precise outcomes. Notably, o3 has achieved record-breaking scores on benchmarks such as the ARC-AGI, a visual reasoning test that had remained unbeaten since its inception in 2019. In low-compute scenarios, o3 scored 75.7%, and in high-compute settings, it reached 87.5%, comparable to human performance at an 85% threshold.

The ARC-AGI benchmark is a challenging test created to assess how well AI models can perform tasks requiring human-like reasoning. Unlike many AI tasks that involve recognizing patterns in data, ARC-AGI focuses on evaluating abstraction, logic, and the ability to generalize from limited examples.

For years, this benchmark has been a hurdle for AI models, with no significant progress until now. The o3 models are the first to achieve human-comparable performance on this benchmark, marking a milestone in reasoning-focused AI.

The o3-mini variant offers a streamlined version of o3, maintaining robust reasoning capabilities while operating with greater efficiency, making it suitable for a wider range of applications.

Access and Availability

Currently, both o3 and o3-mini are in the testing phase. OpenAI is conducting internal safety evaluations and has invited external researchers to apply for testing these models before their public release. The application window for external testers is open until January 10, 2025. OpenAI plans to release o3-mini by the end of January 2025, followed by the full o3 model shortly thereafter.
