OpenAI is making a strong comeback after facing stiff competition from DeepSeek, especially after the release of the DeepSeek R1 model. However, OpenAI has now introduced the O3 Mini, a cost-efficient AI model that is part of the Reasoning Series. This model is available via OpenAI’s API and can also be accessed for free through ChatGPT, albeit with some limitations.
Why O3 Mini Stands Out
- Cost Efficiency: 93% cheaper than the O1 model and 63% cheaper than the O1 Mini.
- Performance: Outperforms the O1 Mini in reasoning tasks and comes close to the O1 model.
- Benchmark Success: Achieved an impressive 49.3 score on the Software Engineering Benchmark (Suway Bench).
- Fast & Reliable: Generates code and responses quickly with minimal errors.
