This week, Microsoft revealed multiple novel “open” artificial intelligence models, with the most formidable rivaling OpenAI’s O3-Mini on a specific benchmark.
Introduction to Microsoft’s Innovative AI Models via Permissive Licensing
Each of these newly introduced, unrestricted models—Phi 4 Mini Reasoning, Phi 4 Reasoning, and Phi 4 Reasoning Plus—falls under the “reasoning” model category. These models are engineered to allocate more time to verifying solutions to intricate challenges. These additions broaden Microsoft’s Phi “small model” lineup, initially launched a year prior to assist AI developers in constructing edge applications.
Key Features of Phi 4 Mini Reasoning
Phi 4 Mini Reasoning underwent training using approximately one million synthetic mathematical problems, generated by R1, a reasoning model developed by DeepSeek, a Chinese AI startup. With around 3.8 billion parameters, Phi 4 Mini Reasoning is tailor-made for educational purposes, such as incorporated tutoring on lightweight devices.
Understanding Parameters in AI Models
In general, parameters correlate with a model’s problem-solving capabilities, with higher parameter counts typically resulting in superior performance.
Applications of Phi 4 Reasoning
Phi 4 Reasoning, boasting 14 billion parameters, was trained on superior web data and refined examples from OpenAI’s O3-Mini. Microsoft recommends this model for applications in mathematics, science, and coding.
Enhancements in Phi 4 Reasoning Plus
Microsoft’s Phi 4 Reasoning Plus is an adaptation of its previously released Phi-4 model, transformed into a reasoning model to enhance accuracy on specific tasks. According to Microsoft, Phi 4 Reasoning Plus approaches the efficiency of R1, a model with a significantly greater parameter count (671 billion). Internal benchmarking also shows Phi 4 Reasoning Plus aligning with O3-Mini on the OmniMath assessment, a test designed to gauge mathematical proficiency. Otherwise known as reasoning skills.
Accessibility and Support for AI Developers
Accessible on Hugging Face, a platform for AI developers, Phi 4 Mini Reasoning, Phi 4 Reasoning, and Phi 4 Reasoning Plus come with comprehensive technical reports to aid developers in deployment.
“By leveraging distillation, reinforcement learning, and high-quality data, these [new] models harmonize size and performance,” Microsoft stated in their blog. “They are compact enough for low-latency settings while maintaining robust reasoning abilities that compete with much larger models. This equilibrium enables even resource-constrained devices to accomplish intricate reasoning tasks effectively.”
