Next.js creator Guillermo Rauch praises GLM-5.2, saying its coding capabilities could shift software development expectations
Story Overview
Vercel CEO and Next.js creator Guillermo Rauch singled out GLM-5.2 for coding performance that surprised him enough to question current assumptions about AI tools, spotlighting a new open-weight model from Beijing-based Z.ai that rolled out first to paid subscribers before hitting Hugging Face under an MIT license.

Developer Impact
Agentic features arrive ready for repo-scale work
The model ships with a usable million-token context, two thinking-effort modes, and explicit positioning for long-horizon coding agents, letting developers plug it into tools like ZCode or third-party platforms without regional locks.
Open Question
Independent scores remain thin on the ground
No official benchmarks accompanied the launch, leaving the strength of its coding claims to user reports and third-party tests that have so far surfaced only scattered results rather than head-to-head numbers.
Sentiment
Users are excited about GLM-5.2's strong coding performance after the Vercel CEO's praise because they find the model's abilities impressive and promising for future coding tools.

OpenModels@openmodels_
@rauchg @Zai_org same reaction, GLM-5.2 is surprisingly strong at coding
we offer it on OpenModels with 1M context, $1.182/M input + $4.136/M output, and pay-as-you-go credits
very compelling for longer agent/coding runs

@rauchg @Zai_org GLM-5.2’s coding throughput numbers are up 37% vs 4.1 on our internal SWE-bench fork. If that holds against production loads, the tier chart just got a new top right quadrant.
