## ✨ What is phidata?

A toolkit for building AI Assistants using LLM function calling.

Assistants can achieve any task by intelligently choosing their course of action by [function calling](https://platform.openai.com/docs/guides/function-calling).

They come with built-in **memory**, **knowledge**, **storage** and **tools**, making it easy to build any kind of RAG, Autonomous or Multimodal application. For example:

- **PDF Assistants:** Answer questions using PDFs.
- **Data Assistants:** Analyze data by running SQL queries.
- **Python Assistants:** Perform tasks by running python code.
- **Stock Assistants:** Analyze stocks and research companies.
- **Marketing Assistants:** Provide marketing insights, copywriting and content ideas.
- **Sales Assistants:** Answer customer queries using product descriptions and purchase history.
- **Customer Support Assistants:** Answer customer queries using user manuals.
- **Real Estate Assistants:** Help search property listings using neighborhood information and user preferences.
- **Travel Assistants:** Help plan travel by researching destinations and booking tickets.
- **Meal Prep Assistants:** Help plan meals by researching recipes and adding ingredients to shopping lists.

After building an Assistant, serve it using **Streamlit**, **FastApi** or **Django** to build an AI App.

## 👩‍💻 Getting Started

<summary><h3>Structured output from a Movie Assistant</h3></summary>

One of our favorite features is generating structured data (i.e. a pydantic model) from sparse information.
Meaning we can use LLMs 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`

```python
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

```shell
python movie_assistant.py
```

- See how the assistant generates a structured output

```shell
MovieScript(
│   setting='A bustling and vibrant New York City',
│   ending='The protagonist saves the city and reconciles with their estranged family.',
│   genre='action',
│   name='City Pulse',
│   characters=['Alex Mercer', 'Nina Castillo', 'Detective Mike Johnson'],
│   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.'

<summary><h3>Create a PDF Assistant with Knowledge & Storage</h3></summary>

- **Knowledge Base:** information that an 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](https://docs.docker.com/desktop/install/mac-install/) for running PgVector in a container.
- Create a file `resources.py` with the following contents

```python
from phi.docker.app.postgres import PgVectorDb
from phi.docker.resources import DockerResources

# -*- PgVector running on port 5432:5432
vector_db = PgVectorDb(
    pg_user="ai",
    pg_password="ai",
    pg_database="ai",
    debug_mode=True,
)

# -*- DockerResources
dev_docker_resources = DockerResources(apps=[vector_db])
```

- Start `PgVector` using

```shell
phi start resources.py
```

- Create a file `pdf_assistant.py` and install libraries using `pip install pgvector pypdf psycopg sqlalchemy`

```python
import typer
from rich.prompt import Prompt
from typing import Optional, List
from phi.assistant import Assistant
from phi.storage.assistant.postgres import PgAssistantStorage
from phi.knowledge.pdf import PDFUrlKnowledgeBase

        if len(existing_run_ids) > 0:
            run_id = existing_run_ids[0]

    assistant = Assistant(
        run_id=run_id,
        user_id=user,
        knowledge_base=knowledge_base,

    if run_id is None:
        run_id = assistant.run_id
        print(f"Started Run: {run_id}\n")
    else:
        print(f"Continuing Run: {run_id}\n")

    assistant.knowledge_base.load(recreate=False)
    while True:
        message = Prompt.ask(f"[bold] :sunglasses: {user} [/bold]")
        if message in ("exit", "bye"):
            break
        assistant.print_response(message)


if __name__ == "__main__":
    typer.run(recipe_assistant)
```

- Run the `pdf_assistant.py` file

```shell
python pdf_assistant.py
```

- Ask a question:

```

<summary><h3>Build an AI App using Streamlit, FastApi and PgVector</h3></summary>

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 <a href="https://docs.phidata.com/ai-app/run-local" target="_blank" rel="noopener noreferrer">here</a>.

### Step 1: Create your codebase

Create your codebase using the `ai-app` template

```shell
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

<a href="https://streamlit.io" target="_blank" rel="noopener noreferrer">Streamlit</a> allows us to build micro front-ends and is extremely useful for building basic applications in pure python. Start the `app` group using:

```shell
phi ws up --group app
```

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

#### PDF Assistant

- Open <a href="http://localhost:8501" target="_blank" rel="noopener noreferrer">localhost:8501</a> 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

<img width="800" alt="chat-with-pdf" src="https://github.com/phidatahq/phidata/assets/22579644/a8eff0ac-963c-43cb-a784-920bd6713a48">

### 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:

```shell
phi ws up --group api
```

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

- View API Endpoints

- Open <a href="http://localhost:8000/docs" target="_blank" rel="noopener noreferrer">localhost:8000/docs</a> 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:

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

Start `jupyter` using:


```shell
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 <a href="http://localhost:8888" target="_blank" rel="noopener noreferrer">localhost:8888</a> 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:

```shell
phi ws down
```

### Step 5: Run your AI App on AWS

Read how to <a href="https://docs.phidata.com/quickstart/run-aws" target="_blank" rel="noopener noreferrer">run your AI App on AWS</a>.
