Brief

GLM 5.2 is drawing strong acclaim: AndrewCurran notes a flurry of positive reactions over 48 hours (June 2026), while Jeremy Howard praises Zai_org's release as matching or exceeding Opus 4.8 and GPT 5.5. Reviewers highlight speed, low cost, restrained verbosity, superior long-context handling, and open-weights availability.

Why it matters

AndrewCurran (posting 2026-06-19) reports widespread positive reactions to GLM 5.2 across his timeline over the prior 48 hours, calling it part of an 'exceptional month' for open source.

Key details

  • Jeremy Howard (@jeremyphoward) says GLM 5.2 (by Zai_org) is 'at least' as good as Opus 4.8 and GPT 5.5, highlighting it as very fast, inexpensive, not overly verbose, and unusually capable with long-context understanding and nuanced judgment.
  • Both posts emphasize that GLM 5.2 uses open weights, and Jeremy notes he's never before experienced that level of capability from an open-weights model.

Wow.

@Zai_org GLM 5.2 is a marvel! It is at least as good as Opus 4.8 and GPT 5.5. It's super fast, inexpensive, and not too verbose.

It responds with nuance and judgement, & handles long context VERY well.

I've never experienced an open weights model like this before.
