-## Introduction
-This is the old version: The G4F AsyncClient 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 AsyncClient API.
-
-## Key Features
-   - **Custom Providers**: Use custom providers for enhanced flexibility.
-   - **ChatCompletion Interface**: Interact with chat models through the ChatCompletion class.
-   - **Streaming Responses**: Get responses iteratively as they are received.
-   - **Non-Streaming Responses**: Generate complete responses in a single call.
-   - **Image Generation and Vision Models**: Support for image-related tasks.
-
-## Getting Started
-**To ignore DeprecationWarnings related to the AsyncClient, you can use the following code:***
-```python
-import warnings
-
-# Ignore DeprecationWarning for AsyncClient
-warnings.filterwarnings("ignore", category=DeprecationWarning, module="g4f.client")
-```
-
-### Initializing the Client
-**To use the G4F `Client`, create a new instance:**
-```python
-from g4f.client import AsyncClient
-from g4f.Provider import OpenaiChat, Gemini
-
-client = AsyncClient(
-    provider=OpenaiChat,
-    image_provider=Gemini,
-    # Add other parameters as needed
-)
-```
-
-## Creating Chat Completions
-**Here's an improved example of creating chat completions:**
-```python
-response = await async_client.chat.completions.create(
-    model="gpt-3.5-turbo",
-    messages=[
-        {
-            "role": "user",
-            "content": "Say this is a test"
-        }
-    ]
-     # Add other parameters as needed
-)
-```
-
-**This example:**
-   - Asks a specific question `Say this is a test`
-   - Configures various parameters like temperature and max_tokens for more control over the output
-   - Disables streaming for a complete response
-
-You can adjust these parameters based on your specific needs.
-
-### Configuration
-**Configure the `AsyncClient` with additional settings:**
-```python
-client = Client(
-    api_key="your_api_key_here",
-    proxies="http://user:pass@host",
-    # Add other parameters as needed
-)
-```
-
-## Usage Examples
-### Text Completions
-**Generate text completions using the ChatCompletions endpoint:**
-```python
-import asyncio

-
-async def main():
-    client = AsyncClient()
-    
-    task1 = client.chat.completions.async_create(
-        model="gpt-3.5-turbo",
-        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())
-```
-
-## Available Models and Providers
-This is the old version: 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:**
-
-### Models
-   - GPT-3.5-Turbo
-   - GPT-4
-   - DALL-E 3
-   - Gemini
-   - Claude (Anthropic)
-   - And more...
-
-### Providers
-   - OpenAI
-   - Google (for Gemini)
-   - Anthropic
-   - Bing
-   - Custom providers
-
-**To use a specific model or provider, specify it when creating the client or in the API call:**
-```python
-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!"
-        }
-    ]
-)
-```
-
-## Error Handling and Best Practices
-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:**
-
-1. **Use try-except blocks to catch and handle exceptions:**
-```python
-try:
-    response = await client.chat.completions.async_create(
-        model="gpt-3.5-turbo",
-        messages=[
-            {
-                "role": "user",
-                "content": "Hello, world!"
-            }
-        ]
-    )
-except Exception as e:
-    print(f"An error occurred: {e}")
-```
-
-2. **Check the response status and handle different scenarios:**
-```python
-if response.choices:
-    print(response.choices[0].message.content)
-else:
-    print("No response generated")
-```
-
-3. **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
-This is the old version: 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
-```
-
-2. **Monitor your API usage and implement logging:**
-```python
-import logging
-
-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
-```
-
-## Conclusion
-This is the old version: The G4F AsyncClient 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.
