haimaker Python SDK

Basic Usage

Non-streaming example

Basic Text Generation

from litellm.google_genai import agenerate_content
from google.genai.types import ContentDict, PartDict
import os

# Set API key
os.environ["GEMINI_API_KEY"] = "your-gemini-api-key"

contents = ContentDict(
    parts=[
        PartDict(text="Hello, can you tell me a short joke?")
    ],
    role="user",
)

response = await agenerate_content(
    contents=contents,
    model="gemini/gemini-2.0-flash",
    max_tokens=100,
)
print(response)

Streaming example

Streaming Text Generation

from litellm.google_genai import agenerate_content_stream
from google.genai.types import ContentDict, PartDict
import os

# Set API key
os.environ["GEMINI_API_KEY"] = "your-gemini-api-key"

contents = ContentDict(
    parts=[
        PartDict(text="Write a long story about space exploration")
    ],
    role="user",
)

response = await agenerate_content_stream(
    contents=contents,
    model="gemini/gemini-2.0-flash",
    max_tokens=500,
)

async for chunk in response:
    print(chunk)

Sync Usage

haimaker Proxy Server

1. Setup config.yaml

model_list:
    - model_name: gemini-flash
      litellm_params:
        model: gemini/gemini-2.0-flash
        api_key: os.environ/GEMINI_API_KEY

2. Start proxy

litellm --config /path/to/config.yaml

3. Test it!

Google GenAI SDK

Google GenAI SDK with haimaker Proxy

from google.genai import Client
import os

# Configure Google GenAI SDK to use haimaker proxy
os.environ["GOOGLE_GEMINI_BASE_URL"] = "http://localhost:4000"
os.environ["GEMINI_API_KEY"] = "sk-1234"

client = Client()

response = client.models.generate_content(
    model="gemini-flash",
    contents=[
        {
            "parts": [{"text": "Write a short story about AI"}],
            "role": "user"
        }
    ],
    config={"max_output_tokens": 100}
)
