lemonai 0.1.0

Lemon AI's A Python client. Grant your LLM agents access to a wide range of APIs for read and write operations, creating copilots in minutes and unlocking the true potential of LLMs.

🍋 Lemon AI

Gateway to empower LLM agents to interact with the world

Build powerful AI assistants in minutes and automate workflows by allowing for accurate and reliable read and write operations in tools like Airtable, Hubspot, Discord, Notion, Slack and Github.

Most connectors available today are focused on read-only operations, limiting the potential of LLMs. Agents, on the other hand, have a tendency to hallucinate from time to time due to missing context or instructions.

With Lemon AI, it is possible to give your agents access to well-defined APIs for reliable read and write operations. In addition, Lemon AI functions allow you to further reduce the risk of hallucinations by providing a way to statically define workflows that the model can rely on in case of uncertainty.

⚡️ Getting Started

1. Prerequisites

Requires Python 3.8.1 and above.

2. Installing

To use Lemon AI in your Python project run pip install lemonai. The following example uses an OpenAI model. Therefore, we also need to pip install openai. Depending on which model you want to use this install is optional.

3. (Optional) Launch the Server

The interaction of your agents and all Lemon AI tools is provided by the Lemon AI Server. Per default the Lemon AI Python client is sending requests to a hosted server version. To run the Lemon AI server on-prem please refer to the Server Documentation.

4. Use Lemon AI with LangChain

The easiest way to give Lemon AI a try is via the Jupyter Notebook you can find in the LangChain Docs.

Lemon AI automatically solves given tasks by finding the right combination of relevant tools or uses Lemon AI Functions as an alternative. The following example demonstrates how to retrieve a user from Hackernews and write it to a table in Airtable:

Include Lemon AI in your LangChain project

import os
from lemonai import execute_workflow
from langchain import OpenAI

Load API Keys and Access Tokens

To use tools that require authentication, you have to store the corresponding access credentials in your environment in the format "{tool name}_{authentication string}" where the authentication string is one of ["API_KEY", "SECRET_KEY", "SUBSCRIPTION_KEY", "ACCESS_KEY"] for API keys or ["ACCESS_TOKEN", "SECRET_TOKEN"] for authentication tokens. Examples are "OPENAI_API_KEY", "BING_SUBSCRIPTION_KEY", "AIRTABLE_ACCESS_TOKEN".

""" Load all relevant API Keys and Access Tokens into your environment variables """
os.environ["OPENAI_API_KEY"] = "*INSERT OPENAI API KEY HERE*"
os.environ["AIRTABLE_ACCESS_TOKEN"] = "*INSERT AIRTABLE TOKEN HERE*"

Define your prompt and execute the LangChain Agent

hackernews_username = "*INSERT HACKERNEWS USERNAME HERE*"
"""
Guidelines on identifying Airtable ids here:
https://www.highviewapps.com/kb/where-can-i-find-the-airtable-base-id-and-table-id/
"""
airtable_base_id = "*INSERT BASE ID HERE*"
airtable_table_id = "*INSERT TABLE ID HERE*"

""" Define your instruction to be given to your LLM """
prompt = f"""Read information from Hackernews for user {hackernews_username} and then write the results to
Airtable (baseId: {airtable_base_id}, tableId: {airtable_table_id}). Only write the fields "username", "karma"
and "created_at_i". Please make sure that Airtable does NOT automatically convert the field types.
"""

"""
Use the Lemon AI execute_workflow wrapper
to run your LangChain agent in combination with Lemon AI
"""
model = OpenAI(temperature=0)

execute_workflow(llm=model, prompt_string=prompt)

(Optional) Define your Lemon AI Functions

Similar to OpenAI functions, Lemon AI provides the option to define workflows as reusable functions. These functions can be defined for use cases where it is especially important to move as close as possible to near-deterministic behavior. Specific workflows can be defined in a separate lemonai.json. You can find the corresponding tool ids (e.g. hackernews-get-user) in the Tool Docs:

[
  {
    "name": "Hackernews Airtable User Workflow",
    "description": "retrieves user data from Hackernews and appends it to a table in Airtable",
    "tools": ["hackernews-get-user", "airtable-append-data"]
  }
]

Your model will have access to these functions and will prefer them over self-selecting tools to solve a given task. All you have to do is to let the agent know that it should use a given function by including the function name in the prompt (e.g. prompt = f"""Execute the Hackernews Airtable user workflow...).

4. Gain transparency on your Agent's decision making

To gain transparency on how your Agent interacts with Lemon AI tools to solve a given task, all decisions made, tools used and operations performed are written to a local lemonai.log file. Every time your LLM agent is interacting with the Lemon AI tool stack a corresponding log entry is created:

2023-06-26T11:50:27.708785+0100 - b5f91c59-8487-45c2-800a-156eac0c7dae - hackernews-get-user
2023-06-26T11:50:39.624035+0100 - b5f91c59-8487-45c2-800a-156eac0c7dae - airtable-append-data
2023-06-26T11:58:32.925228+0100 - 5efe603c-9898-4143-b99a-55b50007ed9d - hackernews-get-user
2023-06-26T11:58:43.988788+0100 - 5efe603c-9898-4143-b99a-55b50007ed9d - airtable-append-data

By using the Lemon AI Analytics Tool you can easily gain a better understanding of how frequently and in which order tools are used. As a result, you can identify weak spots in your agent’s decision-making capabilities and move to a more deterministic behavior by defining Lemon AI functions.
