The G4F async client API is a powerful asynchronous interface for interacting with various AI models. This guide provides comprehensive information on how to use the API effectively, including setup, usage examples, best practices, and important considerations for optimal performance.
The G4F async client API is designed to be compatible with the OpenAI API, making it easy for developers familiar with OpenAI's interface to transition to G4F.
The G4F async client API is an asynchronous version of the standard G4F Client API. It offers the same functionality as the synchronous API but with improved performance due to its asynchronous nature. This guide will walk you through the key features and usage of the G4F async client API.
To use the G4F Client
, create a new instance:
from g4f.client import Client
from g4f.Provider import OpenaiChat, Gemini
client = Client(
provider=OpenaiChat,
image_provider=Gemini,
# Add other parameters as needed
)
Here’s an improved example of creating chat completions:
response = await async_client.chat.completions.create(
model="gpt-4o-mini",
messages=[
{
"role": "user",
"content": "Say this is a test"
}
]
# Add other parameters as needed
)
This example:
Say this is a test
You can adjust these parameters based on your specific needs.
Configure the Client
with additional settings:
client = Client(
api_key="your_api_key_here",
proxies="http://user:pass@host",
# Add other parameters as needed
)
Generate text completions using the ChatCompletions endpoint:
import asyncio
from g4f.client import Client
async def main():
client = Client()
response = await client.chat.completions.async_create(
model="gpt-4o-mini",
messages=[
{
"role": "user",
"content": "Say this is a test"
}
]
)
print(response.choices[0].message.content)
asyncio.run(main())
Process responses incrementally as they are generated:
import asyncio
from g4f.client import Client
async def main():
client = Client()
stream = await client.chat.completions.async_create(
model="gpt-4",
messages=[
{
"role": "user",
"content": "Say this is a test"
}
],
stream=True,
)
async for chunk in stream:
if chunk.choices[0].delta.content:
print(chunk.choices[0].delta.content, end="")
asyncio.run(main())
Analyze an image and generate a description:
import g4f
import requests
import asyncio
from g4f.client import Client
async def main():
client = Client()
image = requests.get("https://raw.githubusercontent.com/xtekky/gpt4free/refs/heads/main/docs/cat.jpeg", stream=True).raw
response = await client.chat.completions.async_create(
model=g4f.models.default,
provider=g4f.Provider.Bing,
messages=[
{
"role": "user",
"content": "What's in this image?"
}
],
image=image
)
print(response.choices[0].message.content)
asyncio.run(main())
Generate images using a specified prompt:
import asyncio
from g4f.client import Client
async def main():
client = Client()
response = await client.images.async_generate(
prompt="a white siamese cat",
model="flux"
)
image_url = response.data[0].url
print(f"Generated image URL: {image_url}")
asyncio.run(main())
import asyncio
from g4f.client import Client
async def main():
client = Client()
response = await client.images.async_generate(
prompt="a white siamese cat",
model="flux",
response_format="b64_json"
)
base64_text = response.data[0].b64_json
print(base64_text)
asyncio.run(main())
Execute multiple tasks concurrently:
import asyncio
from g4f.client import Client
async def main():
client = Client()
task1 = client.chat.completions.async_create(
model="gpt-4o-mini",
messages=[
{
"role": "user",
"content": "Say this is a test"
}
]
)
task2 = client.images.async_generate(
model="flux",
prompt="a white siamese cat"
)
chat_response, image_response = await asyncio.gather(task1, task2)
print("Chat Response:")
print(chat_response.choices[0].message.content)
print("Image Response:")
print(image_response.data[0].url)
asyncio.run(main())
The G4F AsyncClient supports a wide range of AI models and providers, allowing you to choose the best option for your specific use case. Here's a brief overview of the available models and providers:
To use a specific model or provider, specify it when creating the client or in the API call:
client = AsyncClient(provider=g4f.Provider.OpenaiChat)
# or
response = await client.chat.completions.async_create(
model="gpt-4",
provider=g4f.Provider.Bing,
messages=[
{
"role": "user",
"content": "Hello, world!"
}
]
)
Implementing proper error handling and following best practices is crucial when working with the G4F AsyncClient API. This ensures your application remains robust and can gracefully handle various scenarios. Here are some key practices to follow:
Use try-except blocks to catch and handle exceptions:
try:
response = await client.chat.completions.async_create(
model="gpt-4o-mini",
messages=[
{
"role": "user",
"content": "Hello, world!"
}
]
)
except Exception as e:
print(f"An error occurred: {e}")
Check the response status and handle different scenarios:
if response.choices:
print(response.choices[0].message.content)
else:
print("No response generated")
Implement retries for transient errors: ```python import asyncio from tenacity import retry, stop_after_attempt, wait_exponential
@retry(stop=stop_after_attempt(3), wait=wait_exponential(multiplier=1, min=4, max=10)) async def make_api_call():
# Your API call here
pass
## Rate Limiting and API Usage
When working with the G4F AsyncClient API, it's important to implement rate limiting and monitor your API usage. This helps ensure fair usage, prevents overloading the service, and optimizes your application's performance. Here are some key strategies to consider:
1. **Implement rate limiting in your application:**
```python
import asyncio
from aiolimiter import AsyncLimiter
rate_limit = AsyncLimiter(max_rate=10, time_period=1) # 10 requests per second
async def make_api_call():
async with rate_limit:
# Your API call here
pass
logging.basicConfig(level=logging.INFO) logger = logging.getLogger(name)
async def make_api_call():
try:
response = await client.chat.completions.async_create(...)
logger.info(f"API call successful. Tokens used: {response.usage.total_tokens}")
except Exception as e:
logger.error(f"API call failed: {e}")
3. **Use caching to reduce API calls for repeated queries:**
```python
from functools import lru_cache
@lru_cache(maxsize=100)
def get_cached_response(query):
# Your API call here
pass
The G4F async client API provides a powerful and flexible way to interact with various AI models asynchronously. By leveraging its features and following best practices, you can build efficient and responsive applications that harness the power of AI for text generation, image analysis, and image creation.
Remember to handle errors gracefully, implement rate limiting, and monitor your API usage to ensure optimal performance and reliability in your applications.
