โœจ What is phidata?

Phidata is a toolkit for building AI Assistants using function calling.

Function calling enables LLMs to achieve tasks by calling functions and intelligently choosing their next step based on the response, just like how humans solve problems.

assistants

โญ๏ธ How it works

  • Step 1: Create an Assistant
  • Step 2: Add Tools (functions), Knowledge (vectordb) and Storage (database)
  • Step 3: Serve using Streamlit, FastApi or Django to build your AI application

๐Ÿ‘ฉโ€๐Ÿ’ป Getting Started

Installation

pip install -U phidata

Create an Assistant

  • Create a file assistant.py and install openai using pip install openai
from phi.assistant import Assistant

assistant = Assistant(description="You help people with their health and fitness goals.")
assistant.print_response("Share a quick healthy breakfast recipe.")
  • Run the Assistant
python assistant.py
  • Add the ability to search DuckDuckGo
from phi.assistant import Assistant
from phi.tools.duckduckgo import DuckDuckGo

assistant = Assistant(tools=[DuckDuckGo()], show_tool_calls=True)
assistant.print_response("Whats happening in France?")
  • Run the Assistant
pip install duckduckgo-search

python assistant.py

๐Ÿš€ Demos

  • PDF AI that summarizes and answers questions from PDFs.
  • ArXiv AI that answers questions about ArXiv papers using the ArXiv API.
  • HackerNews AI that interacts with the HN API to summarize stories, users, find out what's trending, summarize topics.
  • Demo Streamlit App serving a PDF, Image and Website Assistant (password: admin)
  • Demo FastApi serving a PDF Assistant.

Phidata Tutorial

๐ŸŽ–๏ธ Templates

After building an Assistant, serve it using Streamlit, FastApi or Django to build your AI application. Instead of wiring these tools manually, phidata provides pre-built templates for AI Apps that you can run locally or deploy to AWS with 1 command. Here's how they work:

  • Create your AI App using a template: phi ws create
  • Run your app locally: phi ws up
  • Run your app on AWS: phi ws up prd:aws

๐Ÿ“– Examples

Create an Assistant with a function call

  • Create a file hn_assistant.py that can call a function to summarize the top stories on Hacker News
import json
import httpx

from phi.assistant import Assistant


def get_top_hackernews_stories(num_stories: int = 10) -> str:
    """Use this function to get top stories from Hacker News.

    Args:
        num_stories (int): Number of stories to return. Defaults to 10.

    Returns:
        str: JSON string of top stories.
    """

    # Fetch top story IDs
    response = httpx.get('https://hacker-news.firebaseio.com/v0/topstories.json')
    story_ids = response.json()

    # Fetch story details
    stories = []
    for story_id in story_ids[:num_stories]:
        story_response = httpx.get(f'https://hacker-news.firebaseio.com/v0/item/{story_id}.json')
        story = story_response.json()
        if "text" in story:
            story.pop("text", None)
        stories.append(story)
    return json.dumps(stories)

assistant = Assistant(tools=[get_top_hackernews_stories], show_tool_calls=True)
assistant.print_response("Summarize the top stories on hackernews?")
  • Run the hn_assistant.py file
python hn_assistant.py
  • See it work through the problem

Generate pydantic models using an Assistant

One of our favorite features is generating structured data (i.e. a pydantic model) from sparse information. Meaning we can use Assistants to return pydantic models and generate content which previously could not be possible. In this example, our movie assistant generates an object of the MovieScript class.

  • Create a file movie_assistant.py
from typing import List
from pydantic import BaseModel, Field
from rich.pretty import pprint
from phi.assistant import Assistant


class MovieScript(BaseModel):
    setting: str = Field(..., description="Provide a nice setting for a blockbuster movie.")
    ending: str = Field(..., description="Ending of the movie. If not available, provide a happy ending.")
    genre: str = Field(..., description="Genre of the movie. If not available, select action, thriller or romantic comedy.")
    name: str = Field(..., description="Give a name to this movie")
    characters: List[str] = Field(..., description="Name of characters for this movie.")
    storyline: str = Field(..., description="3 sentence storyline for the movie. Make it exciting!")


movie_assistant = Assistant(
    description="You help people write movie ideas.",
    output_model=MovieScript,
)

pprint(movie_assistant.run("New York"))
  • Run the movie_assistant.py file
python movie_assistant.py
  • See how the assistant generates a structured output
MovieScript(
โ”‚   setting='A bustling and vibrant New York City',
โ”‚   ending='The protagonist saves the city and reconciles with their estranged family.',
โ”‚   genre='action',
โ”‚   name='City Pulse',
โ”‚   characters=['Alex Mercer', 'Nina Castillo', 'Detective Mike Johnson'],
โ”‚   storyline='In the heart of New York City, a former cop turned vigilante, Alex Mercer, teams up with a street-smart activist, Nina Castillo, to take down a corrupt political figure who threatens to destroy the city. As they navigate through the intricate web of power and deception, they uncover shocking truths that push them to the brink of their abilities. With time running out, they must race against the clock to save New York and confront their own demons.'

Create a PDF Assistant with Knowledge & Storage

  • Knowledge Base: information that the Assistant can search to improve its responses. Uses a vector db.
  • Storage: provides long term memory for Assistants. Uses a database.

Let's run PgVector as it can provide both, knowledge and storage for our Assistants.

  • Install docker desktop for running PgVector in a container.
  • Create a file resources.py with the following contents
from phi.docker.app.postgres import PgVectorDb

# -*- DockerResources
dev_docker_resources = DockerResources(apps=[vector_db])
  • Start PgVector using
phi start resources.py

  • Message bye to exit, start the app again and ask:
What was my last message?

See how the assistant now maintains storage across sessions.

  • Run the pdf_assistant.py file with the --new flag to start a new run.
python pdf_assistant.py --new
  • Stop PgVector

Play around and then stop PgVector using phi stop resources.py

phi stop resources.py

Build an AI App using Streamlit, FastApi and PgVector

Phidata provides pre-built templates for AI Apps that you can use as a starting point. The general workflow is:

  • Create your codebase using a template: phi ws create
  • Run your app locally: phi ws up dev:docker
  • Run your app on AWS: phi ws up prd:aws

Let's build an AI App using GPT-4 as the LLM, Streamlit as the chat interface, FastApi as the backend and PgVector for knowledge and storage. Read the full tutorial here.

Step 1: Create your codebase

Create your codebase using the ai-app template

phi ws create -t ai-app -n ai-app

This will create a folder ai-app with a pre-built AI App that you can customize and make your own.

Step 2: Serve your App using Streamlit

Streamlit allows us to build micro front-ends and is extremely useful for building basic applications in pure python. Start the app group using:

phi ws up --group app

Press Enter to confirm and give a few minutes for the image to download.

PDF Assistant

  • Open localhost:8501 to view streamlit apps that you can customize and make your own.
  • Click on PDF Assistant in the sidebar
  • Enter a username and wait for the knowledge base to load.
  • Choose either the RAG or Autonomous Assistant type.
  • Ask "How do I make chicken curry?"
  • Upload PDFs and ask questions
chat-with-pdf

Step 3: Serve your App using FastApi

Streamlit is great for building micro front-ends but any production application will be built using a front-end framework like next.js backed by a RestApi built using a framework like FastApi.

Your AI App comes ready-to-use with FastApi endpoints, start the api group using:

phi ws up --group api

Press Enter to confirm and give a few minutes for the image to download.

  • View API Endpoints

  • Open localhost:8000/docs to view the API Endpoints.

  • Load the knowledge base using /v1/assitants/load-knowledge-base

  • Test the v1/assitants/chat endpoint with {"message": "How do I make chicken curry?"}

  • The Api comes pre-built with endpoints that you can integrate with your front-end.

Optional: Run Jupyterlab

A jupyter notebook is a must-have for AI development and your ai-app comes with a notebook pre-installed with the required dependencies. Enable it by updating the workspace/settings.py file:

...
ws_settings = WorkspaceSettings(
    ...
    # Uncomment the following line
    dev_jupyter_enabled=True,
...

Start jupyter using:

phi ws up --group jupyter

Press Enter to confirm and give a few minutes for the image to download (only the first time). Verify container status and view logs on the docker dashboard.

View Jupyterlab UI

  • Open localhost:8888 to view the Jupyterlab UI. Password: admin

  • Play around with cookbooks in the notebooks folder.

  • Delete local resources

Step 4: Stop the workspace

Play around and stop the workspace using:

phi ws down

Step 5: Run your AI App on AWS

Read how to run your AI App on AWS.
