GLM-6
Zhipu's Z.ai pushed GLM-5.2 out on June 13 and has kept the point-release drumbeat going all year — GLM-5.3 on August 14 and GLM-5.3 Flash on August 26, both read straight off the catalogs by our own sweep — which is exactly how the GLM line behaves right before a major number. There's no GLM-6 announcement, date, or teaser; there is a lab that ships relentlessly and an API we sweep every 60 seconds. The second GLM-6 answers, ArtificialWatch fires.
Leaks & news, newest first.
GLM-5.3 weights go public, two weeks after launch
Z.ai published GLM-5.3 on Hugging Face under its own GLM-5.3 license, inside the two-week window it gave at launch. The 5.x point releases have not paused yet. via Z.ai · Hugging Face
GLM-5.3 Flash ships with MIT weights
Z.ai released GLM-5.3 Flash, a 320B-parameter MoE with 18B active and native visual input, and published its weights on Hugging Face under the MIT license. via Z.ai docs · Hugging Face
GLM-5.3: same base as 5.2, gains from post-training
Z.ai launched GLM-5.3 on the same base model as GLM-5.2, crediting its gains to scaled-up post-training for coding and cyber defense. It went to the API and the GLM Coding Plan first, with weights promised within two weeks. via Z.ai · SiliconANGLE
Watching — the six is unannounced
No date, no teaser, no benchmark leaks. GLM-6 is on the board because of who's behind it, not what's been said: Zhipu has out-shipped nearly every CN lab this year.
GLM-5.2 ships — the base 5.3 would build on
Z.ai pushed GLM-5.2 mid-June, the latest in a steady run of 5.x point releases. Each one raises the floor the eventual GLM-6 has to clear. via Z.ai · llm-stats
The tell to watch: point releases stop, then the number jumps
The GLM line historically goes quiet on point releases a few weeks before a major version. When the 5.x drumbeat pauses, that's the signal — and the API sweep catches the rest.
The official word.
Zhipu has said nothing official about GLM-6 — the Aug 26 GLM-5.3 Flash release is the freshest word from the lab. When the six answers, it lands on this page and your alert channels the same minute.

We sweep the public catalogs (OpenRouter, models.dev) and Z.ai's own docs every 60 seconds — that is how GLM-5.3 was caught. The moment GLM-6 returns a real answer, your channels fire — email + Chrome push free, SMS and a phone call on paid tiers.
