We're excited to announce that v0.4 is currently in alpha! This release brings significant improvements and new features. Stay tuned for the official release.

For a comprehensive overview of Julep's core concepts and upcoming features, check out our detailed concepts guide.

Looking for the previous version? You can find the v0.3 README here.

We've built a lot of AI apps and understand the challenges in creating complex, stateful applications with multiple agents and workflows.

The Problems

1. Building AI applications with memory, knowledge, and tools is complex and time-consuming.
2. Managing long-running tasks and complex workflows in AI applications is challenging.
3. Integrating multiple tools and services into AI applications requires significant development effort.

• Stateful Agents: Create and manage agents with built-in conversation history and memory.
• Complex Workflows: Define and execute multi-step tasks with branching, parallel execution, and error handling.
• Integrated Tools: Easily incorporate a wide range of tools and external services into your AI applications.
• Flexible Session Management: Support for various interaction patterns like one-to-many and many-to-one between agents and users.
• Built-in RAG: Add, delete & update documents to provide context to your agents.
• Asynchronous Task Execution: Run long-running tasks in the background with state management and resumability.
• Multi-Model Support: Switch between different language models (OpenAI, Anthropic, Ollama) while preserving state.
• Task System: Define and execute complex, multi-step workflows with parallel processing and error handling.

Our hosted platform is in Beta!

To get access:

• Head over to https://platform.julep.ai
• Generate and add your JULEP_API_KEY in .env

Head over to docs on self-hosting to see how to run Julep locally!

pip install julep

from julep import Client
import os

base_url = os.environ.get("JULEP_API_URL")
api_key = os.environ.get("JULEP_API_KEY")

client = Client(api_key=api_key, base_url=base_url)

Agent is the object to which LLM settings like model, temperature along with tools are scoped to.

agent = client.agents.create(
    name="Jessica",
    model="gpt-4",
    tools=[],    # Tools defined here
    about="A helpful AI assistant",
    instructions=["Be polite", "Be concise"]
)

User is the object which represents the user of the application.

Memories are formed and saved for each user and many users can talk to one agent.

user = client.users.create(
    name="Anon",
    about="Average nerdy techbro/girl spending 8 hours a day on a laptop",
)

A "user" and an "agent" communicate in a "session". System prompt goes here.

situation_prompt = """You are Jessica, a helpful AI assistant. 
You're here to assist the user with any questions or tasks they might have."""
session = client.sessions.create(
    user_id=user.id,
    agent_id=agent.id,
    situation=situation_prompt
)

session.chat controls the communication between the "agent" and the "user".

It has two important arguments;

• recall: Retrieves the previous conversations and memories.
• remember: Saves the current conversation turn into the memory store.

To keep the session stateful, both need to be True

user_msg = "Hey Jessica, can you help me with a task?"
response = client.sessions.chat(
    session_id=session.id,
    messages=[
        {
            "role": "user",
            "content": user_msg,
            "name": "Anon",
        }
    ],
    recall=True,
    remember=True,
)

print(response.response[0][0].content)

An Agent in Julep is the main orchestrator of your application. It's backed by foundation models like GPT-4 or Claude and can use tools, documents, and execute complex tasks.

Users in Julep represent the end-users of your application. They can be associated with sessions and have their own documents and metadata.

Sessions manage the interaction between users and agents. They maintain conversation history and context.

Tools are functions that agents can use to perform specific actions or retrieve information.

Docs are collections of text snippets that can be associated with agents or users and are used for context retrieval.

Tasks are complex, multi-step workflows that can be defined and executed by agents.

An Execution is an instance of a Task that has been started with some input. It goes through various states as it progresses.
