nn-tech/MetalGPT-1-AWQ

Description

MetalGPT-1 is a model built upon the Qwen/Qwen3-32B and incorporates both continual pre-training and supervised fine-tuning on domain-specific data from the mining and metallurgy industry.

---

Quantization

For convenience and better efficiency, we also offer this AWQ-quantized checkpoint of the nn-tech/MetalGPT-1 model. Using AWQ 4-bit quantization greatly speeds up inference and reduces memory consumption, without significant impact on quality.
