GLM 5.3 API: a model for code and agents with no token bill

Agents burn tokens faster than people: every step is a new request with a long context. GLM 5.3 on a subscription removes that meter. Run agents in Claude Code, Cursor or your own code and pay only for concurrent tasks.

What GLM 5.3 is for

GLM 5.3 is the model we recommend for programming and agent workflows: it follows multi-step tasks, calls tools and edits code in place.

A 200K token context fits several files, the agent’s step history and project instructions in one request.

Strengths

Follows multi-step tasks and tool calls
200K token context
A good fit for Claude Code, Codex and Cline
Writes tests, refactors and explains changes

Typical tasks

An autonomous agent that fixes failing tests in a loop
Refactor a module and update every call site
Generate tests for existing code
Migrate a project to a new library version

Python example

The official openai library works as is, only the address and key change.

main.py

from openai import OpenAI

client = OpenAI(base_url="https://tenzo-cloud.com/v1", api_key="tc-your-key")

stream = client.chat.completions.create(
    model="glm-5.3",
    messages=[{"role": "user", "content": "Hello!"}],
    stream=True,
)
for chunk in stream:
    print(chunk.choices[0].delta.content or "", end="")

The same with curl

terminal

curl https://tenzo-cloud.com/v1/chat/completions \
  -H "Authorization: Bearer tc-your-key" \
  -H "Content-Type: application/json" \
  -d '{"model": "glm-5.3", "stream": true,
       "messages": [{"role": "user", "content": "Hello!"}]}'

FAQ

How is GLM 5.3 different from Qwen 3.8 Max?

GLM 5.3 is tuned for code and agents, while Qwen 3.8 Max has a larger context (256K tokens) and understands images. For terminal work with an agent try GLM 5.3; for screenshots and very large documents use Qwen.

Does GLM 5.3 understand images?

No, it is a text model. For screenshots and diagrams use Qwen 3.8 Max or the fast models with image support.

Does GLM 5.3 have a token limit?

No. We do not count tokens or bill for them. Only concurrency is limited: as many simultaneous requests as streams you bought, and up to 120 new requests a minute per account.

How do I connect GLM 5.3 to Cursor or Claude Code?

Set the address to https://tenzo-cloud.com/v1, use a key from the dashboard and set the model to glm-5.3. The dashboard has ready configs for Claude Code, Codex, OpenCode, Cursor and VS Code with a test button.

How do I pay without a foreign card?

Prices are in tenge, with rubles and dollars at the exchange rate. Available payment methods are shown at checkout. If none suits you yet, message support in Telegram and we will help.

Try it on your own work

Three free hours with every model, no card and no VPN. Connect Cursor, Claude Code or your own code in a minute.
