GLM-4.5 Air

GLM-4.5 Air is an efficient, cost-optimized variant of GLM-4.5. Ideal for high-volume applications where cost efficiency matters most.

Use Cases

Quick Start

curl https://aiwave.live/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -d '{"model":"glm-4-5-air","messages":[{"role":"user","content":"Hello!"}]}'

What it costs in practice

These figures come straight from the live rate above — monthly token volume multiplied by the per-million price. Adjust the volumes to match your own traffic.

Workload	Assumption	Monthly tokens	Monthly cost
Chatbot	~50k short conversations	5.0M in / 1.5M out	$6.31
Coding assistant	one developer, full-time	20.0M in / 4.0M out	$21.17
RAG / document Q&A	long retrieved contexts	50.0M in / 2.0M out	$36.68

Rates are pulled from the live pricing endpoint. Token accounting is returned in the usage field of every non-streaming response.

Quick start

The endpoint is OpenAI-compatible, so the official SDKs work once you change base_url. Nothing else in your code needs to move.

from openai import OpenAI

client = OpenAI(
    api_key="sk-YOUR_KEY",
    base_url="https://aiwave.live/v1",
)

response = client.chat.completions.create(
    model="glm-4.5-air",
    messages=[{"role": "user", "content": "Hello"}],
)
print(response.choices[0].message.content)
print(response.usage)   # exact token counts for cost tracking

Streaming uses the same server-sent-event format as OpenAI:

stream = client.chat.completions.create(
    model="glm-4.5-air",
    messages=[{"role": "user", "content": "Explain vector search"}],
    stream=True,
)
for chunk in stream:
    delta = chunk.choices[0].delta.content
    if delta:
        print(delta, end="", flush=True)

Node.js, LangChain, LlamaIndex, the Vercel AI SDK, Cursor and Cline all accept a custom base URL, so they work with this model without a dedicated provider plugin. Full parameter reference lives in the Chat Completions docs.

How it compares to sibling models

Same provider, same API surface — the practical difference is price and capability. Because every model here speaks the OpenAI wire format, switching between them is a one-word change to the model field.

Model ID	Input / 1M	Output / 1M
glm-4.7-flash	free	free
glm-4.7-flashx	$0.06	$0.06
glm-4.5-air (this model)	$0.6525	$2.03
glm-4.5	$0.6975	$2.17
glm-4.6	$0.93	$3.41
glm-4.7	$0.93	$3.41
