GLM-5.3 has shipped
Tracking the API and the weights
Z.ai formally launched GLM-5.3 on 14 Aug 2026. This page no longer says “not released.” It now tracks whether the standalone API and open weights actually land. How to use it, and how it differs from 5.2, lives on /glm-5-3-guide. QCode /models still has no glm-5.3.
Updated 2026-09-09
The badge flipped. The shelf did not
It shipped
z.ai/blog/glm-5.3. Same base as 5.2; every gain is post-training. This is no longer an SDK-branch rumor.
Not complete
Coding Plan was live that day. The standalone API is still officially “coming soon.” That is the line this page watches.
Weight promise
Official: full weights after safety evaluation and hardening. This page does not claim they are downloadable.
Not listed here
glm-5.3 went live in Aug 2026. The Zhipu line is now glm-5.3-flash / glm-5.3 / glm-5.2.
What this page is for now
Before 14 Aug 2026 this page said “a sighting is not GA.” GA happened. What remains is when the standalone API is public, when a Hugging Face card appears, and when aggregators follow. How-to moved to /glm-5-3-guide. Here we only track rollout. Vendor benches are not turned into a rank.
The how-to is on the guide
Channel snapshot: Coding Plan on day one; OpenCode Go claimed a same-day listing (channel price, not a Z.ai tariff); weights in about two weeks. Full contrast, thinking levels low / high / max, and the “use 5.2 today” line live on /glm-5-3-guide and /glm-5-3-vs-glm-5-2.
Public timeline
GLM-5.2 ships and becomes the open-weight flagship of the line. It is still the Zhipu flagship you can call on QCode.
5.3 launches. Coding Plan that day. This badge flips from “not released” to “shipped · tracking API / weights.”
Official promise of weights. Standalone API still coming soon. Until that window closes, this page stays an amber tracker.
Confirmed vs still do not write
Confirmed
Launch date 14 Aug 2026; same-base post-training; Coding Plan day one; API coming soon; weights ~two weeks after safety. QCode has no glm-5.3. The guide is /glm-5-3-guide.
Still do not write
Do not write that open weights are downloadable. Do not write that QCode listed 5.3. Do not treat OpenCode’s same-price claim as an official tariff. Pre-launch rumors (“5.3 will have vision / they will skip to 5.5”) are retired.
Wait for the API, or use 5.2 today
Use 5.2 today
You need something you can order from a multi-model catalog now. The id is glm-5.2. See /glm-5-2-guide.
Watch 5.3 land
Watch z.ai/blog, a Hugging Face card, and whether /models ever grows a glm-5.3. Until then use Coding Plan / OpenCode — not this catalog.
When this page flips again
When the standalone API publishes a stable id and a tariff, or when HF shows a downloadable card, update the badge and the timeline. Until then it stays “shipped, not complete.” Do not come here for a call tutorial — that is /glm-5-3-guide.
On QCode
Z.ai has released GLM-5.3. QCode added glm-5.3 in Aug 2026. Today’s Zhipu line is glm-5.3-flash, glm-5.3 and glm-5.2. The guide is /glm-5-3-guide.
GLM-5.3 status FAQ
Did 5.3 ship?
Yes. There is an official blog on 14 Aug 2026. That is not the same as every API or aggregator listing it.
Can I download the open weights?
Official wording: about two weeks, after safety evaluation. This page does not claim they are out. Check Hugging Face; a promise is not a download URL.
Can I call 5.3 on QCode?
Yes. glm-5.3 went live in Aug 2026; the Zhipu line is glm-5.3-flash, glm-5.3 and glm-5.2.
Where is the how-to?
/glm-5-3-guide. Versus 5.2: /glm-5-3-vs-glm-5-2. This page only tracks API / weights.
What changed versus 5.2?
Same base; the jump is post-training. Details and vendor tables belong on the guide. Do not treat guesses from the old “not released” copy as specs.
What should I run today?
Need a call now: glm-5.2. Already on Coding Plan / OpenCode: those channels. Do not look for glm-5.3 on QCode.
