Qwen3-4B-calib-OpenR1-Math-220k-16klen-NVFP4

This is Qwen/Qwen3-4B quantized with LLM Compressor in 4-bit (NVFP4), weights and activations. The calibration step used 512 samples of 16000 tokens, chat template applied, from open-r1/OpenR1-Math-220k.

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.
