Microsoft: Phi 4
Analysis Summary
Microsoft Phi 4 is a small-footprint model priced at $0.065 input and $0.14 output per million tokens, with a strong math index of 18 and a coding index of 11.2 relative to its intelligence index of 10.4. This suggests it punches above its weight on structured reasoning tasks, though its agentic index is very low and it lacks tool use or vision support.
For businesses, the 16K context window is a significant constraint, ruling it out for long-document analysis or extended agentic sessions. It is best suited to focused, short-context tasks such as math problem solving, code generation, or structured data processing where context length is not a bottleneck.
At this price point, it offers good value for narrow, well-scoped tasks. Teams looking for a cheap coding or math assistant for short-context work will find it capable, but those needing broader capability or longer context should look elsewhere.

Editorial notes
Microsoft Phi 4 is a compact, cheap model with strong math and coding scores relative to its size, but a very small 16K context window limits its use in document-heavy business workflows.
