Frequently Asked Questions

Everything you need to know about using the GLM API

What is GLM? How is it different from other models? ▾

GLM is a family of large language models launched by Zhipu AI and developed by a technical team from Tsinghua University. GLM excels at native Chinese understanding while also delivering excellent English performance. GLM-5.3 is the current flagship and supports deep reasoning; GLM-4.5v supports multimodal vision; GLM-4-Flash provides ultra-low-cost, high-speed inference.

Does it support the OpenAI SDK? ▾

Yes! It is fully compatible with the OpenAI SDK (Python, Node.js, Go, etc.). Simply change base_url to https://api.acedata.cloud/v1 and set model to any GLM model name. Your existing OpenAI code can switch to GLM with almost no modifications.

What is the difference between GLM-5.3's deep reasoning and ordinary models? ▾

GLM-5.3 has built-in Thinking reasoning capabilities. The model reasons according to the complexity of the question before providing a final answer. This delivers stronger performance in mathematical proofs, complex logic, programming, and Agent tasks; reasoning Tokens are billed according to the output Token pricing rules.

Is GLM-4-Flash really that inexpensive? ▾

Yes! GLM-4-Flash costs only about $0.001/million tokens for input and about $0.0007/million tokens for output, making it one of the most cost-effective large language models on the market. It is ideal for high-concurrency scenarios such as classification, extraction, and simple conversations, and can significantly reduce AI application costs.

How does pricing work? ▾

Billing is based on Token usage, with input Tokens and output Tokens priced separately. Prices vary by model—from the ultra-low-cost GLM-4-Flash to the flagship GLM-5.3. There are no subscription fees or monthly fees; you pay only for what you use. Available immediately after top-up, and your balance never expires.

Can I use GPT, Claude, Gemini, and GLM at the same time? ▾

Yes! Ace Data Cloud provides multiple LLMs such as GPT, Claude, Gemini, and GLM through a unified OpenAI-compatible interface. Simply change the model parameter to switch between different models. The API format is fully consistent, so there is no need to maintain multiple codebases. The same API Key can access all models.

Installation Scope

Operating System

Configuration Method

Connect the current service in Claude Code:

Current project: Merge the mcpServers service entry below into .mcp.json in the project root directory, retaining the existing configuration.
Current user: Run the command below in the terminal; the configuration can be reused across projects.
Project configuration requires setting ACEDATACLOUD_API_TOKEN in the terminal: use export ACEDATACLOUD_API_TOKEN='YOUR_API_TOKEN' on macOS/Linux, and $env:ACEDATACLOUD_API_TOKEN = 'YOUR_API_TOKEN' in Windows PowerShell; replace YOUR_API_TOKEN with your AceDataCloud API Token.
Run claude in the same terminal where this variable has been set; new terminals or desktop-launched clients must also be able to read this variable.
After entering the Claude Code session, run /mcp to confirm that the service is connected and the tools have been loaded; when using the project configuration for the first time, check and approve the service as prompted.

export ACEDATACLOUD_API_TOKEN='YOUR_API_TOKEN'
claude mcp add --scope user --transport http 'glm-mcp' 'https://glm.mcp.acedata.cloud/mcp' --header 'Authorization: Bearer ${ACEDATACLOUD_API_TOKEN}'
