Experimental NVFP4-quantized build of GLM 5.2 - offered for testing only. The published NVFP4 results look very flattering, but we're skeptical of its real quality and performance: this checkpoint was NOT QAT post-trained for NVFP4 (the QAT-on-NVFP4 models are where we've seen the best quality), so treat the benchmarks with caution. Play with it, push it, and see how far it gets you - for production work we recommend the fp8 `umans-glm-5.2`. It runs on a single low-capacity GPU with no fallback, so expect it to go down under load: crash it, let it restart, and play again.
