Microsoft: Phi 4
🇺🇸 Microsoft · Phi 4
Overview
Microsoft: Phi 4 is a large language model API from Microsoft, part of its Phi 4 model family. At $0.070 per million input tokens and $0.140 per million output tokens, it sits in the budget tier — among the cheaper options for high-throughput or cost-sensitive workloads. Output tokens cost about 2× as much as input, so prompt-heavy workloads run noticeably cheaper than generation-heavy ones. The 16K-token context window — around 25 pages of text — comfortably handles long documents, multi-file code, or extended conversations. All prices on this page reflect OpenRouter's routed rates and are re-synced automatically every day; confirm against the provider's official pricing before committing to production.
