I've been developing both AI and non-AI applications for some time now. While creating a prototype can be relatively straightforward, building AI systems that are truly ready for the real world is a much more challenging task.
The software needs to be
- Reliable and well-maintained.
- Adhere to security standards (SOC2, ISO, GDPR, etc).
- Scalable, Performant, Fail-safe, and so on.
Despite all the buzz around AI, the ecosystem for developing production-ready AI applications is still in its early stages.
However, considerable progress has been made recently, thanks to advancements in open-source software.
So, I have compiled a list of open-source software to help you build production-ready AI applications.

1. Composio 👑: Seamless Integration of Tools with LLMs 🔗
I have built my tools for LLM tool calling and have used tools from LangChain and LLamaHub, but I was never satisfied with the accuracy, and many applications are unavailable.
However, this was not the case with Composio. It has over 100 tools and integrations, including but not limited to Gmail, Google Calendar, GitHub, Slack, Jira, etc.
It handles user authentication and authorization for integrations on your users' behalf. So you can build your AI applications in peace. And it’s SOC2 certified.
So, here’s how you can get started with it.
Python
pip install composio-core
Add a GitHub integration.
composio add github
Composio handles user authentication and authorization on your behalf.
Here is how you can use the GitHub integration to star a repository.
from openai import OpenAI
from composio_openai import ComposioToolSet, App
openai_client = OpenAI(api_key="******OPENAIKEY******")
# Initialise the Composio Tool Set
composio_toolset = ComposioToolSet(api_key="**\\*\\***COMPOSIO_API_KEY**\\*\\***")
## Step 4
# Get GitHub tools that are pre-configured
actions = composio_toolset.get_actions(actions=[Action.GITHUB_ACTIVITY_STAR_REPO_FOR_AUTHENTICATED_USER])
## Step 5
my_task = "Star a repo ComposioHQ/composio on GitHub"
# Create a chat completion request to decide on the action
response = openai_client.chat.completions.create(
model="gpt-4-turbo",
tools=actions, # Passing actions we fetched earlier.
messages=[
{"role": "system", "content": "You are a helpful assistant."},
{"role": "user", "content": my_task}
]
)
Run this Python script to execute the given instruction using the agent.
Javascript
You can Install it using npm, yarn, or pnpm.
npm install composio-core
Define a method to let the user connect their GitHub account.
import { OpenAI } from "openai";
import { OpenAIToolSet } from "composio-core";
const toolset = new OpenAIToolSet({
apiKey: process.env.COMPOSIO_API_KEY,
});
async function setupUserConnectionIfNotExists(entityId) {
const entity = await toolset.client.getEntity(entityId);
const connection = await entity.getConnection('github');
if (!connection) {
// If this entity/user hasn't already connected, the account
const connection = await entity.initiateConnection(appName);
console.log("Log in via: ", connection.redirectUrl);
return connection.waitUntilActive(60);
}
return connection;
}
Add the required tools to the OpenAI SDK and pass the entity name on to the executeAgent function.
async function executeAgent(entityName) {
const entity = await toolset.client.getEntity(entityName)
await setupUserConnectionIfNotExists(entity.id);
const tools = await toolset.get_actions({ actions: ["github_activity_star_repo_for_authenticated_user"] }, entity.id);
const instruction = "Star a repo ComposioHQ/composio on GitHub"
const client = new OpenAI({ apiKey: process.env.OPEN_AI_API_KEY })
const response = await client.chat.completions.create({
model: "gpt-4-turbo",
messages: [{
role: "user",
content: instruction,
}],
tools: tools,
tool_choice: "auto",
})
console.log(response.choices[0].message.tool_calls);
await toolset.handle_tool_call(response, entity.id);
}
executeGithubAgent("joey")
Execute the code and let the agent do the work for you.
Composio works with famous frameworks like LangChain, LlamaIndex, CrewAi, etc.

2. Weaviate: The AInative Database for AI Apps 🧠
If you want to build AI applications that depend on semantic retrieval, you need a vector database. Unlike traditional databases, a vector database can manage high-dimensional vector embeddings efficiently. It becomes essential for RAG-based applications.
Weaviate is one of the leading AI-native vector databases. It is fast, efficient, scalable, and has a rapidly growing community of developers.
It has SDKs for multiple programming languages, including Go, Python, JS/TS, and Java.
To get started with Weaviate install
pip install -U weaviate-client
Import the modules and create a Weavite Client.
import weaviate
import weaviate.classes as wvc
import os
import requests
import json
# Best practice: store your credentials in environment variables
wcd_url = os.environ["WCD_DEMO_URL"]
wcd_api_key = os.environ["WCD_DEMO_RO_KEY"]
openai_api_key = os.environ["OPENAI_APIKEY"]
client = weaviate.connect_to_weaviate_cloud(
cluster_url=wcd_url, # Replace with your Weaviate Cloud URL
auth_credentials=wvc.init.Auth.api_key(wcd_api_key), # Replace with your Weaviate Cloud key
headers={"X-OpenAI-Api-Key": openai_api_key} # Replace with appropriate header key/value pair for the required API
)
Create a collection, load the data, and close the client.
try:
# ===== define collection =====
questions = client.collections.create(
name="Question",
vectorizer_config=wvc.config.Configure.Vectorizer.text2vec_openai(), # If set to "none", you must always provide vectors yourself. It could be any other "text2vec-*" also.
generative_config=wvc.config.Configure.Generative.openai() # Ensure the `generative-open` module is used for generative queries.
)
# ===== import data =====
resp = requests.get('https://raw.githubusercontent.com/weaviate-tutorials/quickstart/main/data/jeopardy_tiny.json')
data = json.loads(resp.text) # Load data
question_objs = list()
for i, d in enumerate(data):
question_objs.append({
"answer": d["Answer"],
"question": d["Question"],
"category": d["Category"],
})
questions = client.collections.get("Question")
questions.data.insert_many(question_objs)
finally:
client.close() # Close client gracefully
Now, query the collection.
try:
# Replace with your code. Close the client gracefully in the final block.
questions = client.collections.get("Question")
response = questions.query.near_text(
query="biology",
limit=2
)
print(response.objects[0].properties) # Inspect the first object
finally:
client.close() # Close client gracefully
For more information and implementation for other clients, refer to Weaviate’s documentation.

3. Haystack: Framework for Building Efficient RAG 🛠️
If I were building a real-world RAG application, Haystack would be my choice. It is an orchestration framework for efficiently building RAG pipelines. It’s easy to use and reliable, with all the bells and whistles, such as re-rankers, document loaders, vector db support, RAG evaluators, etc.
Whether it's RAG, Q&A, or semantic searches, Haystack's highly composable pipelines make development, maintenance, and deployment a breeze.
Haystack is a Python-only framework; you can install it using pip.
pip install haystack-ai
Now, build your first RAG Pipeline with Haystack components.
import os
from haystack import Pipeline, PredefinedPipeline
import urllib.request
os.environ["OPENAI_API_KEY"] = "Your OpenAI API Key"
urllib.request.urlretrieve("https://www.gutenberg.org/cache/epub/7785/pg7785.txt", "davinci.txt")
indexing_pipeline = Pipeline.from_template(PredefinedPipeline.INDEXING)
indexing_pipeline.run(data={"sources": ["davinci.txt"]})
rag_pipeline = Pipeline.from_template(PredefinedPipeline.RAG)
query = "How old was he when he died?"
result = rag_pipeline.run(data={"prompt_builder": {"query":query}, "text_embedder": {"text": query}})
print(result["llm"]["replies"][0])
For more tutorials and concepts, check out their documentation.

4. LitGPT: Pretrain, Finetune, Deploy Models At Scale 🚀
In many cases, proprietary LLMs may not be sufficient. It could be cost or hyper-personalization. You will need LLMs personalized for your particular use cases. This is where model fine-tuning comes into the picture.
LitGPT from Lightning AI is arguably the best repository out there for fine-tuning LLMs on custom data. It offers 20+ LLMs to pre-train, fine-tune, and deploy at scale.
Every LLM is implemented from scratch with no abstractions and full control, making it blazing fast, minimal, and performant at the enterprise scale.
It supports popular recipes such as LoRA, QLoRA, FSDP, DPO, and PPO to fine-tune LLMs. It also has free Jupyter Notebooks with Nvidia Tesla T4 and Nvidia A10 GPUs in the Lightning Studio to play around with.
Install LitGPT
pip install 'litgpt[all]'
Load and use any of the 20+ LLMs:
from litgpt import LLM
llm = LLM.load("microsoft/phi-2")
text = llm.generate("Fix the spelling: Every fall, the familly goes to the mountains.")
print(text)
# Corrected Sentence: Every fall, the family goes to the mountains.
Check out the repository on various implementation codes.
5. DsPy: Framework for Programming LLMs 💻
One of the main challenges hindering the widespread integration of LLMs into existing software systems is their stochastic nature. While these models generate the most probable outcomes for a given task, this contrasts with the deterministic nature of traditional software development.
It requires tedious, prompt engineering. Hacking and fine-tuning. DsPy is bridging the gap. It offers a systematic way of working with LLMs.
DSPy from Stanford simplifies this by doing two key things:
- Separating Program Flow from Parameters: This feature keeps your program's flow (the steps you take) separate from the details of how each step is done (the LM prompts and weights). This makes it easier to manage and update your system.
- Introducing New Optimizers: DSPy uses advanced algorithms that automatically fine-tune the LM prompts and weights based on your goals, such as improving accuracy or reducing errors.
Check out this Getting Started Notebook for more on how to work with DsPy.
6. Portkey’s Gateway: Reliably Route to over 200 LLMs with a unified API 🌐
While building AI applications, we usually depend on hosted LLMs from different providers; what if the model goes down? This can be very costly to businesses. You need an efficient model router to route requests from one provider to another during downtime.
PortKey does exactly the same thing and more. It provides a unified API for more than 200 LLM providers. It supports caching, load-balancing, routing, and retries and can be edge-deployed for minimum latency.
This is an essential piece in building fault-tolerant, robust AI systems. It is available in Python, Go, Rust, Java, Ruby, and Javascript.
Get started with Gateway by installing it.
pip install -qU portkey-ai openai
For OpenAI models,
from openai import OpenAI
from portkey_ai import PORTKEY_GATEWAY_URL, createHeaders
client = OpenAI(
api_key=OPENAI_API_KEY,
base_url=PORTKEY_GATEWAY_URL,
default_headers=createHeaders(
provider="openai",
api_key=PORTKEY_API_KEY
)
)
chat_complete = client.chat.completions.create(
model="gpt-4",
messages=[{"role": "user",
"content": "What's a fractal?"}],
)
print(chat_complete.choices[0].message.content)
For Anthropic models,
from openai import OpenAI
from portkey_ai import PORTKEY_GATEWAY_URL, createHeaders
client = OpenAI(
api_key=userdata.get('ANTHROPIC_API_KEY')
base_url=PORTKEY_GATEWAY_URL,
default_headers=createHeaders(
provider="anthropic",
api_key=PORTKEY_API_KEY
),
)
response = client.chat.completions.create(
model="claude-3-opus-20240229",
messages=[{"role": "user",
"content": "What's a fractal?"}],
max_tokens= 512
)
For more information, visit the official repository.
7. AirByte: Reliable and Extensible Open source Data Pipeline 🔄
Data is critical for building AI applications, and in production, you would need to handle a large amount of data from multiple sources. This is where AIrByte shines.
Airbyte provides the largest catalog of 300+ connectors for APIs, databases, data warehouses, and data lakes.
AirByte has a Python extension called PyAirByte. It supports popular frameworks like LangChain and LlamaIndex, allowing you to move data from multiple sources to your GenAI applications conveniently.
Check out this notebook for details on the implementation of PyAirByte with LangChain.
For more information, check out the documentation.
8. AgentOps: Agents Observability and Monitoring 🕵️♂️
Like traditional software systems, AI agents also require constant observation, monitoring, and improvements for optimum performance.
AgentOps is the leading solution in this space. It helps developers build, evaluate, and monitor AI agents. Tools to build agents from prototype to production.
It offers tools for replay analytics, LLM cost management, agent benchmarking, compliance and security and integrates natively with frameworks like CrewAI, AutoGen, and LangChain.
Get started with AgentOps by installing it through pip.
pip install agentops
Initialize the AgentOps client and automatically get analytics on every LLM call.
import agentops
# Beginning of program's code (i.e. main.py, __init__.py)
agentops.init( < INSERT YOUR API KEY HERE >)
...
# (optional: record specific functions)
@agentops.record_action('sample function being record')
def sample_function(...):
...
# End of program
agentops.end_session('Success')
# Woohoo You're done 🎉
Refer to their documentation for more.

9. ArizeAI’s Phoenix: LLM Observability and Evaluation 🔥
As your AI app grows, keeping track of prompts, retrieval accuracy, and LLM responses will be difficult.
Phoenix is an open-source AI observability platform for experimentation, evaluation, and troubleshooting. It offers tracing with OpenTelemetry, performance benchmarking, versioned datasets, experiment tracking, and inference analysis through visual tools.
Phoenix is vendor and language-agnostic, supporting frameworks like LlamaIndex, LangChain, DSPy, and LLM providers like OpenAI and Bedrock.
It can run in various environments, including Jupyter notebooks, local machines, containers, or the cloud.
It is easy to get started with Phoneix.
'pip install arize-phoenix
To get started, launch the Phoenix app.
import phoenix as px
session = px.launch_app()
This will initiate the Phoneix server.
Now that Phoenix is up and running, you can set up tracking for your AI application to debug your application as the traces stream in.
To use LlamaIndex's one click, you must install the small integration first:
pip install 'llama-index>=0.10.44'
import phoenix as px
from openinference.instrumentation.llama_index import LlamaIndexInstrumentor
import os
from gcsfs import GCSFileSystem
from llama_index.core import (
Settings,
VectorStoreIndex,
StorageContext,
set_global_handler,
load_index_from_storage
)
from llama_index.embeddings.openai import OpenAIEmbedding
from llama_index.llms.openai import OpenAI
import llama_index
# To view traces in Phoenix, you will first have to start a Phoenix server. You can do this by running the following:
session = px.launch_app()
# Initialize LlamaIndex auto-instrumentation
LlamaIndexInstrumentor().instrument()
os.environ["OPENAI_API_KEY"] = "<ENTER_YOUR_OPENAI_API_KEY_HERE>"
# LlamaIndex application initialization may vary
# depending on your application
Settings.llm = OpenAI(model="gpt-4-turbo-preview")
Settings.embed_model = OpenAIEmbedding(model="text-embedding-ada-002")
# Load your data and create an index. Here we've provided an example of our documentation
file_system = GCSFileSystem(project="public-assets-275721")
index_path = "arize-phoenix-assets/datasets/unstructured/llm/llama-index/arize-docs/index/"
storage_context = StorageContext.from_defaults(
fs=file_system,
persist_dir=index_path,
)
index = load_index_from_storage(storage_context)
query_engine = index.as_query_engine()
# Query your LlamaIndex application
query_engine.query("What is the meaning of life?")
query_engine.query("How can I deploy Arize?")
# View the traces in the Phoenix UI
px.active_session().url
Once you've executed a sufficient number of queries (or chats) for your application, you can view the details of the UI by refreshing the browser URL.
Refer to their documentation for more tracing, dataset versioning, and evaluation examples.
