Phi-4 Mini Reasoning 3.8B

A small Microsoft specialist for mathematical reasoning. It is not presented as a general-purpose chat assistant; long reasoning can increase latency.

Officially supported35/100 · Experimental coverage

Exact local Ollama manifest and configuration checked on 2026-10-20. Memory figures are conservative planning estimates; no DeviceTerra inference or speed test is claimed. Microsoft describes this model as designed and tested for mathematical reasoning, not broad general-purpose chat.

Will it run?

MamiLens uses 12 GB as a conservative planning floor for this profile and its listed quantization. This is not measured speed. Processor, backend support, context length, memory bandwidth and other applications still affect the result.

Suggested Ollama artifact

Confirm the tag on the official page before downloading, then run:

ollama run phi4-mini-reasoning:3.8b

Start with a representative non-sensitive task. Record the exact runtime, quantization, context, load time, generation speed, memory use and answer quality.

Evidence and limits

Published context: 128K artifact maximum; practical context depends on memory. The source establishes specifications; it does not guarantee that maximum context fits at the MamiLens minimum RAM floor.
