About

Microsoft launched Phi-3-mini on April 23, 2024: 3.8B parameters trained on 3.3T tokens of heavily filtered web data plus synthetic textbook-style data. Team-reported: 69% on MMLU and 8.38 on MT-bench, which Microsoft frames as rivaling Mixtral 8x7B and GPT-3.5. A 4-bit quantized build runs on an iPhone (A16) at over 12 tokens/sec, and the model ships MIT-licensed with ONNX and GGUF builds for edge deployment plus a 128K-context variant. Honest caveats: it is English-centric; the 'rivals GPT-3.5' framing is Microsoft's own benchmarking and independent evals vary; and the 7B/14B siblings arrived separately under the same family.
