Microsoft: Phi 4

Microsoft Phi 4 is a text-only model with a 16,384-token context window, meaning it handles moderately sized documents but will hit limits on longer workflows. It does not support tool use, native reasoning modes, or structured output, so tasks requiring function calling or guaranteed JSON schemas will need to be handled elsewhere. At $0.065 per million input tokens and $0.14 per million output tokens, Phi 4 sits at a low price point, which makes it worth considering for high-volume text tasks where cost control matters. Its blended benchmark score of 6.4 comes from a single benchmark, so that figure reflects limited coverage and should be treated cautiously rather than as a settled verdict. Teams running straightforward text generation or summarization at scale may find the pricing attractive, but those needing tools, multimodal input, or well-validated performance data will likely need to look at more fully evaluated alternatives.
