GLM 5.3: A Great Model, With a Possible Dealbreaker
Z.ai has finally released GLM 5.3, an incredible model accessible on ZCode. We test its SVG origami crane, procedural 3D globe, wizard floating isles game, and neon runner code generations.

Z.ai has finally released GLM 5.3, which is honestly, an incredible model. So, let me tell you its specs before we dive into benchmarking.
First off, the API for it hasn’t been released, so the only way to access it is through a GLM subscription. However, you can try it for free on their ZCode platform, which is how I got access to it. It performs similarly to Kimi K3 and lags just behind American frontier AI models in benchmarks, so I wonder what the pricing will be, as that will be a major deciding factor.
So, here are its generations for each benchmark
## Crane:

Glass Sphere with Origami Crane
```
Not the best, but I see what it’s trying to do.
## Globe:
```html
Procedural 3D Globe
```
Probably the best one I’ve seen so far.
## Wizard:
```html
Wizard of the Floating Isles
```
Score: 0 / 10

Wizard of the Floating Isles
WASD to move · SPACE to jump · drag mouse to look
Collect 10 crystal artifacts — dodge the elemental turrets!
One glitch really ruins the whole thing
## Neon Runner:

```A pretty decent start for the game.
Overall, it’s a pretty good model, and in my use of it, I found it to be pretty strong for large repository work. However, until we can get an actual price per token for it, I’ll refrain from rating it, but if it keeps the same pricing as its predecessor, I’ll give it an easy 8/10.
