On October 31, 2026, the cheapest GLM 4.5 Air API we found is UberLLM: buyers paid a median of $0.00013 per million input tokens and $0.00085 per million output tokens over the last 24 hours. That is at least 99.9% less on both input and output than the closest other provider we checked, OpenRouter ($0.13 and $0.85). Novita AI, Vercel AI Gateway, Requesty and DeepInfra are higher still. UberLLM adds no fee to these prices, and a request that fails is not billed.

Use the OpenAI SDK or any OpenAI-compatible client: set the base URL to the UberLLM endpoint, use an UberLLM API key and set the model to "z-ai/glm-4.5-air". The Anthropic SDK works too, through /v1/messages.
Why is GLM 4.5 Air cheaper on UberLLM?
UberLLM is a market: sellers offer GLM 4.5 Air capacity below its list price, and each request goes to a seller that can serve it. A request costs what its seller charged, UberLLM adds no fee to it, and every request is listed with its cost in Activity.
Can a request cost more than this price?
Yes, when the lower-priced sellers are busy. Send provider.max_price with the most you will pay per million tokens: the request only goes to sellers at or under it and is never billed above it.
Are there other fees?
UberLLM adds no fee to model prices. A card fee of 5.5% + $0.50 is added when you buy credit. With the 5.5% added, UberLLM's GLM 4.5 Air price is still lower than every other provider in the table.
