Where is Phi-4 hosted?

Phi-4 runs on US hosting routes through the Opper gateway.

Is Phi-4 trained on prompts and outputs?

Phi-4

by Microsoft

Phi-4 is a 14 billion parameter dense decoder-only transformer trained on 9.8 trillion tokens, designed for reasoning-intensive tasks where smaller model size is critical. It exceeds its teacher model on STEM-focused benchmarks, achieving 84.8 on MMLU and 80.4 on MATH, and supports a 16,384 token context window. Built with a data-quality-first approach, Phi-4 strategically incorporates synthetic training data rather than relying solely on organic web content or code. It excels at math problem-solving, code generation, and multi-step reasoning, optimized for memory and compute-constrained environments. The model is trained primarily on English text with multilingual capability (about 8% multilingual data), and follows a chat instruction format. It is fully open-weight and available on Hugging Face, making it accessible for commercial and research applications.
