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”
