About Phi-3 Medium

Phi-3 Medium is Microsoft's 14 billion parameter model in the Phi-3 family, offering a step up in capability from Phi-3 Mini while remaining efficient enough for deployment on consumer hardware. It demonstrates that careful data curation and training methodology can produce models that compete with much larger alternatives, particularly on reasoning and STEM-related tasks.

Frequently Asked Questions

What is Phi-3 Medium?
Phi-3 Medium is Microsoft's 14 billion parameter model in the Phi-3 family, offering a step up in capability from Phi-3 Mini while remaining efficient enough for deployment on consumer hardware. It demonstrates that careful data curation and training methodology can produce models that compete with much larger alternatives, particularly on reasoning and STEM-related tasks.
How much does Phi-3 Medium cost?
Phi-3 Medium 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 Medium's context window?
Phi-3 Medium 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 Medium open source?
Yes, Phi-3 Medium 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 Medium best for?
Phi-3 Medium is best suited for: Balanced performance, reasoning, coding. These use cases leverage the model's specific strengths in terms of capability, speed, and cost-effectiveness within Microsoft's model lineup.
