Which GLM-5.3 model ID should I use?

Use glm-5.3 or glm-5.3-flash for standard GLM at a discount to Z.ai's list price. For fewer refusals, glm-5.3-flash-uncensored has the lowest rate, and the two abliterated IDs are the ones verified with native tool calls in a coding agent.

Rates are per 1M tokens, shown rounded up to the cent; billing uses the exact rate. Z.ai list prices are from its pricing page. A model marked (2) or (3) is an alternative route with its own ID and price.

What should I know before using uncensored GLM-5.3?

Two things change the cost and setup of uncensored GLM: a built-in system prompt on two of the uncensored IDs, and the context and output limits that coding agents need for tool calls.

  • Built-in system prompt

    GLM-5.3 Uncensored and GLM-5.3 Flash Uncensored include a built-in system prompt of about 14,000 tokens that is billed as input on every request. At their rates that adds about $0.0014 per request on GLM-5.3 Flash Uncensored and $0.0028 on GLM-5.3 Uncensored, before your own tokens.

  • Tool calls and limits

    GLM-5.3 Abliterated and GLM-5.3 Flash Abliterated were verified with native tool calls in Roo Code. The setup guide sets a 1,000,000-token context window and a 65,536-token maximum output for GLM.

How do I call the GLM-5.3 API through Outrun?

GLM models on Outrun use the OpenAI Chat Completions format, so the official OpenAI SDKs and any OpenAI-compatible app work with them.

  1. 01

    Get your key

    Open the Telegram bot and copy your personal key. It works for GLM and every other Outrun model.

  2. 02

    Set the base URL

    Use https://api.outrun.to/v1 exactly as shown, without /chat/completions.

  3. 03

    Send a GLM model ID

    Put the full ID, such as glm-5.3 or glm-5.3-abliterated, in the model field.

POST/v1/chat/completions 
curl https://api.outrun.to/v1/chat/completions \
  -H "Authorization: Bearer $OUTRUN_API_KEY" \
  -H "Content-Type: application/json" \

GLM-5.3 API questions

The model docs list every GLM ID with its current rate.

How much does a typical GLM-5.3 request cost?

Can I try GLM-5.3 for free?

Eligible new accounts start with $0.10 in free credit, and the Playground gives every account 10 free web searches a day, so you can compare GLM answers before you connect an app.

Do I need a Z.ai account?

No. One Outrun key and one prepaid USD balance cover GLM and every other model on Outrun. You get the key from the Telegram bot, and eligible new accounts start with $0.10 in free credit.
