Hearing a lot of buzz around GLM-5.3, which I expect to be the best open-source coding model with the weights dropping soon, I wanted to test it where I actually do my work.

I just mapped GLM-5.3 to TokenGo so I could swap out the base URL and use it directly in my IDE.

The backend handles the edge routing via Cloudflare to keep latency low, critical when you're waiting for inline code completions.

If you want to try GLM-5.3 (or glm-5.3-flash) in your own workflow, here is the setup.

For Cursor:

Go to Settings > Models.

Add your API key in the OpenAI API Key field.

Toggle "Override OpenAI Base URL" and set it to: https://api.tokengo.com/v1

Under "Model Names", add z-ai/glm-5.3.

Select it in your chat panel dropdown.

We're one of the first inference providers to get the GLM 5.3 family online and fully accessible for IDEs. If you'd like to try it in a high volume production workload I'd be happy to provide test keys for yall
