Frequently Asked Questions
Everything you need to know about using the GLM API
What is GLM and how does it differ from other models? ▾
GLM is the large language model family from Zhipu AI, developed by a research team from Tsinghua University. GLM excels at native Chinese understanding while performing strongly in English. GLM-5.1 is the current flagship with deep reasoning; GLM-4.5v supports multimodal vision; GLM-4-Flash offers ultra-low-cost high-speed inference.
Is the OpenAI SDK supported? ▾
Yes! Fully compatible with the OpenAI SDK (Python, Node.js, Go, etc.). Simply set 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 virtually no changes.
How is GLM-5.1 deep reasoning different from regular models? ▾
GLM-5.1 features a built-in Thinking reasoning mode, similar to OpenAI's o1 series. The model first thinks through the solution steps before providing its final answer. This significantly outperforms standard models on math proofs, complex logic, and programming tasks. Thinking tokens are billed separately at a lower rate.
Is GLM-4-Flash really that affordable? ▾
Yes! GLM-4-Flash input costs approximately $0.001/million tokens, and output about $0.0007/million tokens, making it one of the most cost-effective LLMs available. It's perfect for high-concurrency classification, extraction, and simple conversation scenarios, dramatically reducing AI application costs.
How does pricing work? ▾
Billing is per-token, with separate pricing for input and output tokens. Different models have different rates — from the ultra-affordable GLM-4-Flash to the flagship GLM-5.1. No subscriptions, no monthly fees — pay only for what you use. Top up and start immediately; credits never expire.
Can I use GPT, Claude, Gemini, and GLM together? ▾
Absolutely! Ace Data Cloud provides GPT, Claude, Gemini, GLM, and more through a unified OpenAI-compatible interface. Just change the model parameter to switch between models — the API format stays the same, no need to maintain separate codebases. One API key accesses all models.
