OpenAI just released the long-awaited **o3 model**. Originally teased during the company’s 12-day Christmas event in December 2024, o3 and o3-mini were positioned as a major leap forward—so much so that OpenAI skipped “o2” entirely, citing potential brand confusion with Telefonica’s O2, but likely also to signal a substantial leap forward over OpenAI o1.
After months of back and forth—including a brief detour where [o3 was said to be folded into GPT-5](https://x.com/sama/status/1889755723078443244)—OpenAI has made o3 its new flagship model. It now surpasses o1 across nearly every benchmark, with full tool access in ChatGPT and via API.
**Read on to learn more about o3 and o3-mini. If you also want to read about the newest model, o4-mini, check out this introductory guide on [o4-mini](https://www.datacamp.com/blog/o4-mini).**

## What Is OpenAI o3?
o3 is OpenAI’s latest frontier model, designed to advance reasoning capabilities across a range of complex tasks like coding, math, science, and visual perception.
The o3 reasoning model is the first reasoning model with access to autonomoustool use. This means that o3 can use search, Python, image generation, and interpretation to achieve its tasks.
This has translated into strong performance on advanced benchmarks that test real-world problem-solving, where previous models have struggled. OpenAI highlights o3’s improvement over o1, positioning it as their most capable and versatile model yet.
## O1 vs. O3
o3 builds directly on the foundation set by o1, but the improvements are significant across key areas. OpenAI has positioned o3 as a model designed to handle more complex reasoning tasks, with performance gains reflected in its benchmarks.
### Coding
When tested on software engineering tasks, o3 achieved 69.1% accuracy on the SWE-Bench Verified Software Engineering benchmark, a substantial improvement over o1’s score of 48.9%.

Similarly, in competitive programming, o3 reached an ELO score of 2706, far surpassing o1’s previous high of 1891. Moreover, o3 performs significantly better at code editing benchmarks, with o3 variants outperforming o1 across the board on the Aider Polyglot Code Editing benchmark.
