Asynchronous LLM API Calls in Python: A Comprehensive Guide
New Post has been published on https://thedigitalinsider.com/asynchronous-llm-api-calls-in-python-a-comprehensive-guide/
Asynchronous LLM API Calls in Python: A Comprehensive Guide
As developers and dta scientists, we often find ourselves needing to interact with these powerful models through APIs. However, as our applications grow in complexity and scale, the need for efficient and performant API interactions becomes crucial. This is where asynchronous programming shines, allowing us to maximize throughput and minimize latency when working with LLM APIs.
In this comprehensive guide, we’ll explore the world of asynchronous LLM API calls in Python. We’ll cover everything from the basics of asynchronous programming to advanced techniques for handling complex workflows. By the end of this article, you’ll have a solid understanding of how to leverage asynchronous programming to supercharge your LLM-powered applications.
Before we dive into the specifics of async LLM API calls, let’s establish a solid foundation in asynchronous programming concepts.
Asynchronous programming allows multiple operations to be executed concurrently without blocking the main thread of execution. In Python, this is primarily achieved through the asyncio module, which provides a framework for writing concurrent code using coroutines, event loops, and futures.
Key concepts:
Coroutines: Functions defined with async def that can be paused and resumed.
Event Loop: The central execution mechanism that manages and runs asynchronous tasks.
Awaitables: Objects that can be used with the await keyword (coroutines, tasks, futures).
Here’s a simple example to illustrate these concepts:
import asyncio async def greet(name): await asyncio.sleep(1) # Simulate an I/O operation print(f"Hello, name!") async def main(): await asyncio.gather( greet("Alice"), greet("Bob"), greet("Charlie") ) asyncio.run(main())
In this example, we define an asynchronous function greet that simulates an I/O operation with asyncio.sleep(). The main function uses asyncio.gather() to run multiple greetings concurrently. Despite the sleep delay, all three greetings will be printed after approximately 1 second, demonstrating the power of asynchronous execution.
The Need for Async in LLM API Calls
When working with LLM APIs, we often encounter scenarios where we need to make multiple API calls, either in sequence or parallel. Traditional synchronous code can lead to significant performance bottlenecks, especially when dealing with high-latency operations like network requests to LLM services.
Consider a scenario where we need to generate summaries for 100 different articles using an LLM API. With a synchronous approach, each API call would block until it receives a response, potentially taking several minutes to complete all requests. An asynchronous approach, on the other hand, allows us to initiate multiple API calls concurrently, dramatically reducing the overall execution time.
Setting Up Your Environment
To get started with async LLM API calls, you’ll need to set up your Python environment with the necessary libraries. Here’s what you’ll need:
Python 3.7 or higher (for native asyncio support)
aiohttp: An asynchronous HTTP client library
openai: The official OpenAI Python client (if you’re using OpenAI’s GPT models)
langchain: A framework for building applications with LLMs (optional, but recommended for complex workflows)
You can install these dependencies using pip:
pip install aiohttp openai langchain <div class="relative flex flex-col rounded-lg">
Basic Async LLM API Calls with asyncio and aiohttp
Let’s start by making a simple asynchronous call to an LLM API using aiohttp. We’ll use OpenAI’s GPT-3.5 API as an example, but the concepts apply to other LLM APIs as well.
import asyncio import aiohttp from openai import AsyncOpenAI async def generate_text(prompt, client): response = await client.chat.completions.create( model="gpt-3.5-turbo", messages=["role": "user", "content": prompt] ) return response.choices[0].message.content async def main(): prompts = [ "Explain quantum computing in simple terms.", "Write a haiku about artificial intelligence.", "Describe the process of photosynthesis." ] async with AsyncOpenAI() as client: tasks = [generate_text(prompt, client) for prompt in prompts] results = await asyncio.gather(*tasks) for prompt, result in zip(prompts, results): print(f"Prompt: promptnResponse: resultn") asyncio.run(main())
In this example, we define an asynchronous function generate_text that makes a call to the OpenAI API using the AsyncOpenAI client. The main function creates multiple tasks for different prompts and uses asyncio.gather() to run them concurrently.
This approach allows us to send multiple requests to the LLM API simultaneously, significantly reducing the total time required to process all prompts.
Advanced Techniques: Batching and Concurrency Control
While the previous example demonstrates the basics of async LLM API calls, real-world applications often require more sophisticated approaches. Let’s explore two important techniques: batching requests and controlling concurrency.
Batching Requests: When dealing with a large number of prompts, it’s often more efficient to batch them into groups rather than sending individual requests for each prompt. This reduces the overhead of multiple API calls and can lead to better performance.
import asyncio from openai import AsyncOpenAI async def process_batch(batch, client): responses = await asyncio.gather(*[ client.chat.completions.create( model="gpt-3.5-turbo", messages=["role": "user", "content": prompt] ) for prompt in batch ]) return [response.choices[0].message.content for response in responses] async def main(): prompts = [f"Tell me a fact about number i" for i in range(100)] batch_size = 10 async with AsyncOpenAI() as client: results = [] for i in range(0, len(prompts), batch_size): batch = prompts[i:i+batch_size] batch_results = await process_batch(batch, client) results.extend(batch_results) for prompt, result in zip(prompts, results): print(f"Prompt: promptnResponse: resultn") asyncio.run(main())
Concurrency Control: While asynchronous programming allows for concurrent execution, it’s important to control the level of concurrency to avoid overwhelming the API server or exceeding rate limits. We can use asyncio.Semaphore for this purpose.
import asyncio from openai import AsyncOpenAI async def generate_text(prompt, client, semaphore): async with semaphore: response = await client.chat.completions.create( model="gpt-3.5-turbo", messages=["role": "user", "content": prompt] ) return response.choices[0].message.content async def main(): prompts = [f"Tell me a fact about number i" for i in range(100)] max_concurrent_requests = 5 semaphore = asyncio.Semaphore(max_concurrent_requests) async with AsyncOpenAI() as client: tasks = [generate_text(prompt, client, semaphore) for prompt in prompts] results = await asyncio.gather(*tasks) for prompt, result in zip(prompts, results): print(f"Prompt: promptnResponse: resultn") asyncio.run(main())
In this example, we use a semaphore to limit the number of concurrent requests to 5, ensuring we don’t overwhelm the API server.
Error Handling and Retries in Async LLM Calls
When working with external APIs, it’s crucial to implement robust error handling and retry mechanisms. Let’s enhance our code to handle common errors and implement exponential backoff for retries.
import asyncio import random from openai import AsyncOpenAI from tenacity import retry, stop_after_attempt, wait_exponential class APIError(Exception): pass @retry(stop=stop_after_attempt(3), wait=wait_exponential(multiplier=1, min=4, max=10)) async def generate_text_with_retry(prompt, client): try: response = await client.chat.completions.create( model="gpt-3.5-turbo", messages=["role": "user", "content": prompt] ) return response.choices[0].message.content except Exception as e: print(f"Error occurred: e") raise APIError("Failed to generate text") async def process_prompt(prompt, client, semaphore): async with semaphore: try: result = await generate_text_with_retry(prompt, client) return prompt, result except APIError: return prompt, "Failed to generate response after multiple attempts." async def main(): prompts = [f"Tell me a fact about number i" for i in range(20)] max_concurrent_requests = 5 semaphore = asyncio.Semaphore(max_concurrent_requests) async with AsyncOpenAI() as client: tasks = [process_prompt(prompt, client, semaphore) for prompt in prompts] results = await asyncio.gather(*tasks) for prompt, result in results: print(f"Prompt: promptnResponse: resultn") asyncio.run(main())
This enhanced version includes:
A custom APIError exception for API-related errors.
A generate_text_with_retry function decorated with @retry from the tenacity library, implementing exponential backoff.
Error handling in the process_prompt function to catch and report failures.
Optimizing Performance: Streaming Responses
For long-form content generation, streaming responses can significantly improve the perceived performance of your application. Instead of waiting for the entire response, you can process and display chunks of text as they become available.
import asyncio from openai import AsyncOpenAI async def stream_text(prompt, client): stream = await client.chat.completions.create( model="gpt-3.5-turbo", messages=["role": "user", "content": prompt], stream=True ) full_response = "" async for chunk in stream: if chunk.choices[0].delta.content is not None: content = chunk.choices[0].delta.content full_response += content print(content, end='', flush=True) print("n") return full_response async def main(): prompt = "Write a short story about a time-traveling scientist." async with AsyncOpenAI() as client: result = await stream_text(prompt, client) print(f"Full response:nresult") asyncio.run(main())
This example demonstrates how to stream the response from the API, printing each chunk as it arrives. This approach is particularly useful for chat applications or any scenario where you want to provide real-time feedback to the user.
Building Async Workflows with LangChain
For more complex LLM-powered applications, the LangChain framework provides a high-level abstraction that simplifies the process of chaining multiple LLM calls and integrating other tools. Let’s look at an example of using LangChain with async capabilities:
This example shows how LangChain can be used to create more complex workflows with streaming and asynchronous execution. The AsyncCallbackManager and StreamingStdOutCallbackHandler enable real-time streaming of the generated content.
import asyncio from langchain.llms import OpenAI from langchain.prompts import PromptTemplate from langchain.chains import LLMChain from langchain.callbacks.manager import AsyncCallbackManager from langchain.callbacks.streaming_stdout import StreamingStdOutCallbackHandler async def generate_story(topic): llm = OpenAI(temperature=0.7, streaming=True, callback_manager=AsyncCallbackManager([StreamingStdOutCallbackHandler()])) prompt = PromptTemplate( input_variables=["topic"], template="Write a short story about topic." ) chain = LLMChain(llm=llm, prompt=prompt) return await chain.arun(topic=topic) async def main(): topics = ["a magical forest", "a futuristic city", "an underwater civilization"] tasks = [generate_story(topic) for topic in topics] stories = await asyncio.gather(*tasks) for topic, story in zip(topics, stories): print(f"nTopic: topicnStory: storyn'='*50n") asyncio.run(main())
Serving Async LLM Applications with FastAPI
To make your async LLM application available as a web service, FastAPI is an great choice due to its native support for asynchronous operations. Here’s an example of how to create a simple API endpoint for text generation:
from fastapi import FastAPI, BackgroundTasks from pydantic import BaseModel from openai import AsyncOpenAI app = FastAPI() client = AsyncOpenAI() class GenerationRequest(BaseModel): prompt: str class GenerationResponse(BaseModel): generated_text: str @app.post("/generate", response_model=GenerationResponse) async def generate_text(request: GenerationRequest, background_tasks: BackgroundTasks): response = await client.chat.completions.create( model="gpt-3.5-turbo", messages=["role": "user", "content": request.prompt] ) generated_text = response.choices[0].message.content # Simulate some post-processing in the background background_tasks.add_task(log_generation, request.prompt, generated_text) return GenerationResponse(generated_text=generated_text) async def log_generation(prompt: str, generated_text: str): # Simulate logging or additional processing await asyncio.sleep(2) print(f"Logged: Prompt 'prompt' generated text of length len(generated_text)") if __name__ == "__main__": import uvicorn uvicorn.run(app, host="0.0.0.0", port=8000)
This FastAPI application creates an endpoint /generate that accepts a prompt and returns generated text. It also demonstrates how to use background tasks for additional processing without blocking the response.
Best Practices and Common Pitfalls
As you work with async LLM APIs, keep these best practices in mind:
Use connection pooling: When making multiple requests, reuse connections to reduce overhead.
Implement proper error handling: Always account for network issues, API errors, and unexpected responses.
Respect rate limits: Use semaphores or other concurrency control mechanisms to avoid overwhelming the API.
Monitor and log: Implement comprehensive logging to track performance and identify issues.
Use streaming for long-form content: It improves user experience and allows for early processing of partial results.

Outsourcing academic decisions to tumblr dot com
Further context for each course:
"Weird Fiction" is an English course that will have me reading and annotating tons of short stories. Reading reviews + syllabus online has led me to believe that the prof is strict as hell and not very generous. However if I do ok on the midterm I get to write a short story instead of a final exam. Online synchronous.
"Religon and the body" is a new religion course which is about. Well. Religion and the body, whether that's death rituals, food purity codes, sexuality, etc. Reviews of the prof seem to say she's flexible but the course has also never been taught before so who knows if the content and evaluation format will work for me. Online asynchronous.
#i would LOVE to do the short story stuff if it didnt seem so fucking stressful lol#religion and the body was lowkey my favorite part of my fun religion course last fall#but if the class ends up sucking im gonna be there like.... damn..... i could be reading + writing short stories rn#theyre both online which is fine cause all my other courses are in person that term so it's already lots#asynchronous online is kinda fun cause i just pick a time to sit in the hums lounge and do them#synchronous has more structure#its really a toss up#trying to see if the cool theythem in my program wants to take one or the other with me#my shit

When cell phones and internet go down...
If you're in one of a myriad of marginalized groups who know they can't count on the government to help them, then this post is for you.
I feel like I'm cramming messages into bottles from my fairly niche interest (radio, emergency comms) and chucking them into the sea of Tumble in the hopes it reaches people it can help. What happened in Spain and Portugal recently and some of the cell outages we've seen in recent years - they're is a great example of why back up communication methods aren't just for doomsday preppers.
If cell phones and internet (and possibly power) went out, how would you communicate in an emergency?
Note: this is geared toward the US. It's where I am and it's all I know.
If I only had ~$25
I'd grab a Beofeng UV-5R ($18-$25) if I thought I might study to get my ham license eventually ($15-$25 test fee + $35 FCC fee),
OR
If I knew I didn't want to test for a ham license and thought I might pay $35 for a GMRS license eventually, I'd pay a little extra up front and get a Beofeng UV-5G plus GMRS radio (~$35)
While this would not allow me to transmit usually, this would allow me to:
call for help in an emergency - the license requirement for transmission is lifted in the event of a genuine emergency
listen to weather frequencies - it will not turn on and give you the alert but if you know bad weather is coming, you can turn it on and listen for alerts as they come in. Weather stations give alerts for a fairly broad area so you'll be able to hear about any significant storms as the move into and through your area.
listen to local repeaters - repeaters, in my experience, are kind of a combination of a megaphone and an internet chat room. You set the frequency and the PL tones (password sounds your radio sends) for the repeater and then you can hear people from much further away. This is one, just fun to listen to on a given day but two, a great way to find out information if your area is experiencing an event but you don't require help. Some even have EAS weather alerts (thought this still won't turn your radio on if it's off in an emergency). Use repeaterbook to look for repeaters in your area and use CHIRP to program them into your radio - tutorials abound.
For ~$15 more you can upgrade the UV-5R to a bigger battery and USB-C charging (UV-5G comes with USB-C charging).
This can be thrown in a go bag if you need to evacuate or your housing is unstable. You can have your handheld radio monitoring a local repeater while you have a car or portable radio listening to commercial or public stations for updates.
If I only had ~$100
I would get a GMRS license ($35) and a Beofeng UV-5G plus (~$35) and a single Meshtastic node (~$25).
If I had a little extra, I'd grab a second Meshtastic node for a roommate, partner, family member or nearby friend.
This would get me the ability to not only monitor frequencies but the ability to talk on them in non-emergency times which would be helpful practice. Some GMRS repeaters have regular "nets" - it's basically a meeting on air where someone invited folks to tell them/radio in their call sign (radio license ID basically) and then they confirm they heard you. This gives you a chance to test your equipment.
The GMRS license covers your family so they can pick up a radio as well and then you'd be able to communicate with them as well (as long as they're close enough; 1-5 miles but varies by terrain, more range if using a repeater). It's not a phone so the conversation would be heard by other people but this is great for wellness checks or a quick check up.
Meshtastics add the ability to text people and share GPS coordinates with people near by - encrypted if you so desire. The range is much less (I've only tested it to about a mile currently though with tweaking more is possible). This adds an important link in your communication plan - asynchronous communication. As long as the device is on and paired and in range, you'll most likely receive a message. It does drop occasionally but that's pretty rare. My nesting partner and I often have to rely on them because the internet and cell signal is so poor up here but they serve us incredibly well for that. Beyond the Emergency Comms use, it's just nice for morale to be able to text during an event. Best part is, if you're in an area were other people have them too, you can bounce your signal further for no additional power.
Past this amount of money, I'd still get my GMRS license and encourage my friends and neighbors who didn't want to study for the ham license to get theirs. Then I'd get my ham license and buy the best handheld I could afford - probably one of the value Yaesu models - so I have several ways to both coordinate among my loved ones and get any needs to a net in the area during a disaster.I'd get and pass out several meshtastic devices to people who were within range that I might want to commincate with. I'd look into back up power for recharging (I like my Jackerys).
Amateur radio is a deep well and this barely touches on it of it. Don't let how vast it is keep you thinking it's too complicated for you. I promise it's not. I'm very much a noob myself but I'm happy answer any questions that I can.
This is part of self care - ensuring you can care for yourself during chaotic events and emergencies to the best of your ability. Even a little bit of preparation can keep something like storm outbreak or power outage from turning harmful or even deadly. Learn what you can. You've got this!
