Brief

Graham Neubig reported on 2026-06-19 that GLM-5.2 is a strong open model—potentially the first viable replacement for closed models for most tasks aside from vision. He emphasizes it’s too large to run on a laptop and requests recommendations for vllm/sglang serving recipes to deploy it in production.

Why it matters

Graham Neubig (gneubig) tested GLM-5.2 and calls it "a good model," posted 2026-06-19.

Key details

  • He asserts GLM-5.2 is likely the first open model good enough to replace closed models in workflows except for vision use cases.
  • Neubig asks for current best serving recipes for vllm and sglang, noting GLM-5.2 won't run on a typical laptop.

The Chinese cooked hard-core with this one

OK, I tried GLM-5.2 and this is a good model.

Probably the first model good enough to eschew closed models from your workflow entirely (except if you need vision).

I know this won't run on your laptop, but what are the best current vllm/sglang serving recipes?
