Create a message

Anthropic’s native Messages API for generating model responses. Supports text and image inputs, and text outputs. Create stateful interactions with the model, using the output of previous responses as input. Extend the model’s capabilities with built-in tools for computer use, text editing, and more. Allow the model access to external systems and data using function calling.

pip install anthropic

Basic Example

from anthropic import Anthropic

# Initialize client with custom base URL
client = Anthropic(
    api_key="$GMI_API_KEY",
    base_url="https://api.gmi-serving.com"
)

# Basic message
message = client.messages.create(
    model="anthropic/claude-opus-4.7",
    max_tokens=100,
    messages=[
        {"role": "user", "content": "What is 2+2? Reply with just the number."}
    ]
)
print(message.content[0].text)
print(f"Usage: input={message.usage.input_tokens}, output={message.usage.output_tokens}")

Streaming Example

from anthropic import Anthropic

client = Anthropic(
    api_key="$GMI_API_KEY",
    base_url="https://api.gmi-serving.com"
)

with client.messages.stream(
    model="anthropic/claude-opus-4.7",
    max_tokens=100,
    messages=[
        {"role": "user", "content": "Count from 1 to 5."}
