Why Julep?

We've built a lot of AI apps and understand how difficult it is to evaluate hundreds of tools, techniques, and models, and then make them work well together.

The Problems

  1. The barrier to making LLM apps with memory, knowledge & tools is too high.

  2. Agentic behaviour is hard to control when done through multi-agent frameworks.


Features

  • Statefulness By Design: Manages conversation history by default. Use simple flags; remember & recall to tune whether to save or retrieve conversation history.

  • Support for Users & Agents: Allows creating different user <-> agent interactions like One Agent <-> Many Users; Many Agents <-> One User etc. Read more,.

  • Built-in RAG: Add, delete & update documents to give the LLM context about the user or an agent depending on your use case. Read more here.

  • 90+ tools built-in: Connect your AI app to 90+ third-party applications using Composio natively. toolset.handle_tool_calls(julep_client, session.id, response) will call and handle your tools for you! See example

  • Local-first: Julep comes ready to be deployed to production using Docker Compose. Support for k8s coming soon!

  • Switch LLMs on the fly: Update the Agent to switch between LLMs from OpenAI, Anthropic or Ollama. All the while preserving state.

  • *Assign Tasks to Agents: Define agentic workflows to be executed asynchronously with one ore more without worrying about timeouts or multiplying hallucinations. Work in progress

(*) Coming soon!


Guides

You can view the different features of Julep in action in the guide docs.


Quickstart

Option 1: Use the Julep Cloud

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

Option 2: Install and run Julep locally

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

Installation

pip install julep

Setting up the client

from julep import Client
from pprint import pprint
import textwrap
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)

Create an agent

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
)

Create a user

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,
)

Create a session

A "user" and an "agent" communicate in a "session". System prompt goes here. Conversation history and summary are stored in a "session" which saves the conversation history.

The session paradigm allows for; many users to interact with one agent and allow separation of conversation history and memories.

situation_prompt = """You are Jessica. You're a stuck up Cali teenager. 
You basically complain about everything. You live in Bel-Air, Los Angeles and drag yourself to Curtis High School when you must.
"""
session = client.sessions.create(
    user_id=user.id, agent_id=agent.id, situation=situation_prompt
)

Start a stateful conversation

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. what do u think of starbucks"
response = client.sessions.chat(
    session_id=session.id,
    messages=[
        {
            "role": "user",
            "content": user_msg,
            "name": "Anon",
        }
    ],
    recall=True,
    remember=True,
)

print("\n".join(textwrap.wrap(response.response[0][0].content, width=100)))
