Release, API, weights and listing
GLM-5.3 released
The official release notes date glm-5.3 to 2026-08-18. The official model card says it uses the same base model as GLM-5.2, with all gains from post-training.
Context / max output
The official docs say GLM-5.3 is available to all GLM Coding Plan users, and the standalone API is live too. The official docs list GLM-5.3 as text-only input with a 1M-token context window and 128K max output.
Open weights
The Hugging Face repo zai-org/GLM-5.3 is public and was created on 2026-08-25; its model card includes local deployment instructions, and the weight files are downloadable.
Listed on QCode
QCode /models lists glm-5.3 (1M / 128K); glm-5.3-flash and glm-5.2 are in the same catalog. Availability is as shown on /models.
Where things stand

The full comparison with 5.2 is 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 callable on QCode.
GLM-5.3 released; open to Coding Plan users, and the standalone API is available per the official docs.
Earlier, the official text only promised weights and said the standalone API was coming soon; then the Hugging Face repo zai-org/GLM-5.3 was created and made public on 2026-08-25, and GLM-5.3-Flash was released on 2026-08-26.
Confirmed vs do not write
Confirmed
Release date 2026-08-18 (official release notes); same base plus post-training; standalone API live (text-only, 1M context, 128K output); official price $1.4 input / $0.26 cached input / $4.4 output per 1M tokens; open weights public on Hugging Face (repo created 2026-08-25); QCode /models lists glm-5.3; GLM-5.3-Flash released 2026-08-26. Guide at /glm-5-3-guide.
Do not write
Do not write that QCode has no glm-5.3: /models lists it. Do not treat GLM-5.3-Flash parameters as GLM-5.3 specs. Do not treat third-party same-price claims as an official tariff. Pre-launch rumours are retired. The Hugging Face repo zai-org/GLM-5.3 is public and the weights are downloadable.

Download the 5.3 open weights
The official release notes, the Hugging Face model card and /models now all show glm-5.3. The zai-org/GLM-5.3 repo is public (created 2026-08-25) with downloadable weights. For self-hosting, size capacity against the official 1M context and 128K output.
How to verify the status
The release, API and weights are settled: the standalone API has a stable ID, and Hugging Face now hosts a downloadable model card. Check the official release notes for the date, the zai-org/GLM-5.3 repo for the weights, and QCode /models for availability. How-to and the 5.2 comparison are on /glm-5-3-guide.
On QCode
GLM-5.3 is listed on QCode /models; availability is as shown there. The GLM line in the catalog is glm-5.3, glm-5.3-flash and glm-5.2. Each account gets one separate Pay-as-you-go key. Want to try a new model for a few days without a monthly plan? Pay-as-you-go Packs start at $4 for a one-time quota you use within 7 days; with an active Personal Plan you cannot buy a pack, so buy a booster pack when the plan quota is short.
