The o3 family of AI models represents OpenAI’s latest step in enhancing machine intelligence. Building upon its predecessor, the o1 series, these models are designed to excel in reasoning, problem-solving, and performance. Here’s how the o3 models compare with the o1 series.

ARC-AGI Benchmark

o3 achieved nearly 90% accuracy on the Abstraction and Reasoning Corpus for Artificial General Intelligence. This is almost 3 times the reasoning score of o1 models, which indicates OpenAI’s leap in model advancement.

FrontierMath Benchmark

o3 recorded a 25% accuracy rate in the FrontierMath test, which is a massive leap from the previous best of 2%. This surely showcases it as a standout performer in mathematical reasoning.

Comparison of o3 with Claude, DeepSeek, and Other Models

While o3’s safety test results show it outperforms the o1 series, let’s see how it compares with other existing models, including Claude Sonnet 3.5 and DeepSeek’s V3 and R1.

Codeforces Elo Score

o3 currently leads the Codeforces coding test with a rating score of 2727. It significantly outperforms its predecessor, o1, which scored 1891 and DeepSeek’s latest model R1, which has a rating of 2029. This showcases its enhanced coding proficiency, making it a reliable model for tasks involving advanced algorithms and problem-solving techniques.

SWE-bench Verified Benchmark

o3 has put OpenAI back at the top of the SWE coding test with a score 71.7%. The next best model, DeepSeek R1, with a score of 49.2%, had just surpassed OpenAI’s o1 at 48.9%. This superior performance highlights o3’s strength in handling real-world software engineering problems, including debugging and code verification.
