Qwen3-14B-NVFP4

This is Qwen/Qwen3-14B quantized with LLM Compressor in 4-bit (NVFP4), weights and activations. The calibration step used 512 samples of up to 2048 tokens, chat template applied, from HuggingFaceH4/ultrachat_200k.

The quantization has been done, tested, and evaluated by The Kaitchup. The model is compatible with vLLM. Use a Blackwell GPU to get >2x throughput.
