Prices

Prices are in USD for each million tokens, in the standard tier. The global host bills the global price. A regional host or a regional model ID bills the price of its region.

Regions

Munito AI serves this model in the EU. The global host, api.munito.ai, sends each request to a region that serves it. To keep the processing in one region, use the host of that region:

RegionHost
EUapi.eu.munito.ai

The global host also accepts a regional ID, such as zai-org/glm-5.3-flash@eu, which keeps the request in that region.

See Regions for the base URLs and the rules for stored data.

Example

export MUNITO_API_KEY="munitoai_..."
curl https://api.munito.ai/inference/v1/chat/completions \
  -H "Authorization: Bearer $MUNITO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "zai-org/glm-5.3-flash",
    "messages": [{"role": "user", "content": "Hello!"}],
    "max_tokens": 256
  }'
# pip install openai
import os
from openai import OpenAI

client = OpenAI(
    base_url="https://api.munito.ai/inference/v1",
    api_key=os.environ["MUNITO_API_KEY"],
)
response = client.chat.completions.create(
    model="zai-org/glm-5.3-flash",
    messages=[{"role": "user", "content": "Hello!"}],
    max_tokens=256,
)
print(response.choices[0].message.content)

The same model ID works with the Anthropic client. See Send your first request.
