Microsoft Unleashes New “Open” AI Models, Taking on OpenAI’s o3-mini
The AI landscape is heating up, and Microsoft is making a bold move by launching several new “open” AI models that are competitive with OpenAI’s o3-mini on at least one benchmark. These new models, part of Microsoft’s Phi “small model” family, are designed to be more accessible and usable for developers building apps at the edge.
What’s in a Name?
The new models are called Phi 4 mini reasoning, Phi 4 reasoning, and Phi 4 reasoning plus. The “reasoning” part is key, as these models are capable of spending more time fact-checking solutions to complex problems. This is a significant departure from traditional AI models, which often rely on brute force to solve problems.
The Models
Let’s dive into each model:
- Phi 4 mini reasoning: This 1 million-parameter model was trained on synthetic math problems generated by Chinese AI startup DeepSeek’s R1 reasoning model. It’s designed for educational applications, such as “embedded tutoring” on lightweight devices.
- Phi 4 reasoning: This 14-billion-parameter model was trained using high-quality web data and curated demonstrations from OpenAI’s o3-mini. It’s best suited for math, science, and coding applications.
- Phi 4 reasoning plus: This model is an adaptation of Microsoft’s previously-released Phi 4 model, designed to achieve better accuracy for particular tasks. Microsoft claims it approaches the performance levels of DeepSeek R1, which has significantly more parameters (671 billion).
What Does it Mean?
These new models are significant because they balance size and performance, making them suitable for low-latency environments while maintaining strong reasoning capabilities. This means even resource-limited devices can perform complex reasoning tasks efficiently.
The Impact
The implications of these new models are far-reaching. For developers, it means they can build more sophisticated AI-powered apps without sacrificing performance or requiring significant computational resources. For users, it means they can enjoy more accurate and reliable AI-driven experiences, from educational tools to complex problem-solving applications.
What’s Next?
As the AI landscape continues to evolve, we can expect to see more innovations and advancements in the field. Microsoft’s new models are a significant step forward, and it will be interesting to see how they are adopted and built upon by developers and researchers.
