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.
