GLM-4.7-Flash hits Blackwell deployment snags

A LocalLLaMA Reddit post asks why GLM-4.7-Flash will not run on dual RTX 5090 Blackwell GPUs inside the latest nightly vLLM Docker image, even after updating `transformers`. It is less a product announcement than a real-world compatibility report on how brittle cutting-edge local inference stacks still are on brand-new hardware.

// ANALYSIS

This is the open-model ecosystem in one post: model support lands in docs and nightlies first, then developers spend weeks finding the exact combo that actually works.

–Z.AI positions GLM-4.7-Flash as a lightweight coding-focused member of the GLM-4.7 family with a 200K context window and strong frontend/backend programming performance
–vLLM’s GLM-4.X recipe explicitly calls for nightly vLLM builds for GLM-4.7 support and even recommends installing `transformers` from source, which signals support is still moving fast
–The Blackwell angle matters because dual 5090 setups are exactly where developers expect local inference to get easier, not harder
–Threads like this are useful signal for AI infra teams because they expose the gap between “officially supported” and “actually runs on my box”
