GLM-4.5 Flash API

glm-4.5-flash

GLM-4.5 Flash is a language model from Zhipu, available through the GPUniq API under the identifier `glm-4.5-flash`. Pricing starts at $0.02 per 1M input tokens. It is reachable from the OpenAI-compatible endpoint, so any client that speaks the OpenAI Chat Completions API works by changing two settings: the base URL and the key.

Pricing

Every request is billed on two counters: the tokens you send (prompt, system message, conversation history, any attached images) and the tokens the model generates. Output is the pricier side on essentially every model, and reasoning tokens count as output even when you never see them. Prices below are per 1,000,000 tokens.

Billed for	GPUniq
Inputper 1M tokens	$0.02
Outputper 1M tokens	$0.08

Billed from your GPUniq balance as you use it — no subscription, no monthly minimum, no per-seat fee. Prices refresh from the live catalog hourly.

How to call it

Any OpenAI-compatible client works: change the base URL and the key, keep everything else.

Endpoint

POST /v1/openai/chat/completions

Base URL

https://api.gpuniq.com/v1/openai

  -d '{
    "model": "glm-4.5-flash",
    "messages": [{"role": "user", "content": "Explain rate limiting in one paragraph."}]

Create a key on /chat and send it as a bearer token. The same key works across every model in the catalog, so switching models means changing one string.
