Phi 4 Mini Instruct

NVIDIA
Phi 4 Mini Instruct is a lightweight dense transformer model designed for efficient multilingual reasoning, instruction-following, and agentic tool-calling in constrained environments. It features 3.8B parameters with 32 layers, 3,072 hidden size, and 24 attention heads with grouped-query attention using 8 key-value heads. The model supports a 128K token context window and uses long RoPE scaling for extended context handling. Trained on 5T tokens with supervised fine-tuning and direct preference optimization, it is optimized for low-latency inference and strong reasoning performance.
