Independent reproduction will determine whether Quantprobe can run GLM-4.5-Air’s roughly 110 billion parameters within 16GB of consumer RAM at practically useful speed and quality.

What is this?
Quantprobe claims it can run Z.ai’s open-source GLM-4.5-Air—described in the case as a roughly 110-billion-parameter model—on a consumer machine with 16GB of RAM. The supplied snippets establish that GLM-4.5-Air is the efficiency-focused member of the GLM-4.5 family and supports INT4 quantization, but they conflict sharply on hardware requirements: one says substantial GPU capacity is needed, while another claims quantized versions run on a single RTX 3090 or 4090. None of the snippets independently verifies Quantprobe’s specific 16GB result, its speed, or retained model quality, so reproduction and practical benchmarks remain decisive.
Why it matters to Scott
The claim falls within Scott’s local/open-model inference territory, but no wiki or radar hits connect it to a position, project, or previously tracked development. Without independent benchmarks or a specific Scott-side intersection, it is currently just an unverified example of aggressive consumer-hardware quantization.

No independent reproduction, benchmarks, or discussion emerged within the observation window, so the extreme-quantization claim remains unsupported and has lost momentum.
