Red Hat AI(@RedHat_AI):LLM Compressor v0.14.0 is out, and GPTQ just got its biggest speedup since launch. A new Triton kernel makes quantization ~15x faster end to end. Batching layers that share a shape pushes that to ~30x on some MoE workloads. Even the old eager path is 1.5-2x faster. Also new: expanded MSE/iMatrix observers that beat GPTQ for NVFP4 on internal benchmarks, REAP pruning with distributed DDP, and support for GLM 5.3 and Qwen3.8. Full release notes:
