Phi-4 Mini Flash Reasoning
phi-4-mini-flash-reasoning
Phi-4 Mini Flash Reasoning is a 3.8B reasoning model profile for local AI planning. This page records provider, license, context, quantization, hardware-fit estimates, setup hints, source links, and caveats so readers do not choose a model by name alone.

Hardware fit values are conservative local-inference estimates based on GGUF size plus runtime and KV-cache overhead. Actual requirements depend on context length, quantization, runtime, GPU offload, and other running apps.
BEST FOR
·Fast advanced math reasoning on CUDA stacks where Hugging Face and SGLang setup is acceptable.
AVOID IF
·Avoid as a beginner default until Ollama, GGUF, LM Studio, or MLX paths mature publicly.
CAVEATS
·Best treated as an advanced or watchlist entry until Ollama, GGUF, LM Studio, MLX, and llama.cpp support are manually verified. Microsoft positions it for math reasoning, not broad general assistant use.
·Commercial-use status from the supplied research: Permitted under MIT license; verify deployment stack and application obligations before commercial use.
·Beginner summary from supplied research: Phi-4 Mini Flash Reasoning is the newer fast math-reasoning variant, built around Microsoft’s SambaY hybrid architecture. It looks promising for CUDA developers, but beginner local workflows remain less verified than mini-reasoning for catalog use today.
