Phi-4 Reasoning 14B
A reasoning-focused Phi-4 variant for difficult math, science and coding tasks.
Official artifact verified. Longer reasoning can increase latency and memory use.
- Official model source
- Official engine artifact
Will it run?
LocalLens uses 18 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.

Confirm the tag on the official page before downloading, then run:
ollama run phi4-reasoning:14bStart 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: 32K published max. The source establishes specifications; it does not guarantee that maximum context fits at the LocalLens minimum RAM floor.
