Frequently Asked Questions
What is Phi-3 Mini?▾
Phi-3 Mini is Microsoft's compact 3.8 billion parameter model that delivers surprisingly strong performance for its size, rivaling models many times larger on reasoning and coding benchmarks. It features a 128K context window despite its small size, making it ideal for on-device deployment in mobile phones, laptops, and edge devices where computational resources are severely constrained.
How much does Phi-3 Mini cost?▾
Phi-3 Mini costs Free (open) per 1 million input tokens and Free (open) per 1 million output tokens. Pricing is based on token usage, making it cost-effective for both small and large-scale applications.
What is Phi-3 Mini's context window?▾
Phi-3 Mini has a context window of 128K tokens. This determines how much text the model can process in a single request — larger context windows allow the model to handle longer documents, maintain more conversation history, and reason over bigger codebases.
Is Phi-3 Mini open source?▾
Yes, Phi-3 Mini is open source. This means the model weights are publicly available, allowing developers and organizations to download, fine-tune, and self-host the model on their own infrastructure. Open-source models offer greater flexibility and data privacy control.
What is Phi-3 Mini best for?▾
Phi-3 Mini is best suited for: Edge deployment, mobile, on-device AI. These use cases leverage the model's specific strengths in terms of capability, speed, and cost-effectiveness within Microsoft's model lineup.
