This model requires a specialized High-VRAM environment. Ensure you have the latest CUDA Drivers or Metal Framework installed.
Minimum VRAM: 5GB VRAM Recommended
Origins & History
The Phi 3.5 Mini model by Microsoft is a 3.8B parameter architecture optimized for chat tasks. It requires approximately 2.5GB of VRAM to comfortably run locally using a Q4_K_M quantization. Extending the context window up to 128,000 tokens will dynamically allocate further VRAM, meaning high-bandwidth memory hardware is strictly advised.
Pros
Full privacy and offline inference capabilities
Highly capable 3.8B parameter structure
Supports impressive 128,000 token context window
Cons
Requires 2.5GB+ VRAM minimum
Local inference speed depends entirely on memory bandwidth (GB/s)
Architect's Runtime Strategy
For running Phi 3.5 Mini at maximum tokens-per-second, we recommend using LM Studio or Ollama with a GGUF quantization (Q4_K_M or Q6_K). If you are multi-GPU, use vLLM to distribute the layers across your VRAM pool for optimal throughput.
Common Questions
What hardware do I need to run Phi 3.5 Mini?
You will need a GPU with at least 5GB of VRAM to run the Q4_K_M quantized version smoothly with a moderate context window.
How do I install Phi 3.5 Mini locally?
The simplest method is utilizing Ollama by executing 'ollama run phi3.5' directly in your command line. Alternatively, you can search for the model via LM Studio's interface.
