o3 from OpenAI: The super-powerful AI model that breaks new limits

OpenAI unveils its latest artificial intelligence model, o3, which marks a major advance in natural language processing. This new technology stands out in particular for its exceptional capacity for reasoning and analysis.3-mini video demonstration

➥ A new architecture for enhanced performance

The o3 model introduces an innovative concept: the “private chain of thought”. In practical terms, artificial intelligence takes the time to analyze each problem in depth before formulating an answer. As a result, the results obtained are significantly more accurate, particularly in scientific and mathematical fields.

➥ Very high performance

Tests show impressive results. o3 scored 96.7% on the American Invitational Mathematics 2024 exam, for example. What’s more, on the Codeforces platform, the model achieved a ranking of 2727 points, surpassing even the performance of OpenAI’s Chief Scientist.

➥ A family of models

o3 comes in several versions to suit different use cases. The main version is designed for complex tasks requiring in-depth analysis. In parallel, o3-mini offers three declinations (low, medium, high) tailored to specific needs.

➥ Remarkable results on ARC-AGI

O3’s results on the ARC-AGI (Abstract Reasoning Challenge for AGI) test deserve particular attention. The model succeeded in solving 87% of the abstract puzzles offered, surpassing the scores of earlier versions of GPT.

This performance on ARC-AGI testifies to o3’s ability to understand and manipulate complex abstract concepts, particularly in novel situations requiring advanced spatial and logical reasoning.

Key points to remember

➥ How to test OpenAI’s o3

For the time being, o3 is only available to researchers and testers selected as part of the public safety program. Nevertheless, OpenAI plans to set up a waiting list in early 2025 for developers wishing to experience the beta version.

Registration will be via the OpenAI platform, with priority given to members who have already worked on GPT-4.

➥ A release planned for 2025

OpenAI plans to launch o3-mini at the end of January 2025, followed by the full version of o3. Currently, the model is in the public safety test phase, allowing researchers to evaluate its capabilities.
