This is a [LlamaIndex](https://www.llamaindex.ai/) simple agentic RAG project using [Agent Workflows](https://docs.llamaindex.ai/en/stable/examples/agent/agent_workflow_basic/).
## Getting Started
First, setup the environment with uv:
> **_Note:_** This step is not needed if you are using the dev-container.
```shell
uv sync
```
Then check the parameters that have been pre-configured in the `.env` file in this directory.
Make sure you have set the `OPENAI_API_KEY` for the LLM.
Second, generate the embeddings of the documents in the `./data` directory:
```shell
uv run generate
```
Third, run the development server:
```shell
uv run fastapi dev
```
Then open [http://localhost:8000](http://localhost:8000) with your browser to start the chat UI.
To start the app optimized for **production**, run:
```
uv run fastapi run
```
## Configure LLM and Embedding Model
You can configure [LLM model](https://docs.llamaindex.ai/en/stable/module_guides/models/llms) and [embedding model](https://docs.llamaindex.ai/en/stable/module_guides/models/embeddings) in [settings.py](app/settings.py).
## Use Case
We have prepared an [example workflow](./app/workflow.py) for the agentic RAG use case, where you can ask questions about the example documents in the [./data](./data) directory.
You can start by sending an request on the [chat UI](http://localhost:8000) or you can test the `/api/chat` endpoint with the following curl request:
```
curl --location 'localhost:8000/api/chat' \
--header 'Content-Type: application/json' \
--data '{ "messages": [{ "role": "user", "content": "What standards for a letter exist?" }] }'
```

```
## Customize the UI
To customize the UI, you can start by modifying the [./components/ui_event.jsx](./components/ui_event.jsx) file.
You can also generate a new code for the workflow using LLM by running the following command:
```
uv run generate_ui
```

> **_Note:_** This step is not needed if you are using the dev-container.
```shell

Then check the parameters that have been pre-configured in the `.env` file in this directory.
Make sure you have set the `OPENAI_API_KEY` for the LLM and the `E2B_API_KEY` for the code interpreter. You can get the E2B API key from [here](https://e2b.dev).

A workflow to generate a financial report using indexed documents.
Requirements:
- Indexed documents containing financial data and a query engine tool to search them
- A code interpreter tool to analyze data and generate reports
- A document generator tool to create report files
Steps:
1. LLM Input: The LLM determines the next step based on function calling.
For example, if the model requests the query engine tool, it returns a ResearchEvent;
if it requests document generation, it returns a ReportEvent.
2. Research: Uses the query engine to find relevant chunks from indexed documents.
After gathering information, it requests analysis (step 3).
3. Analyze: Uses a custom prompt to analyze research results and can call the code
interpreter tool for visualization or calculation. Returns results to the LLM.
4. Report: Uses the document generator tool to create a report. Returns results to the LLM.

This is a [LlamaIndex](https://www.llamaindex.ai/) project bootstrapped with [`create-llama`](https://github.com/run-llama/LlamaIndexTS/tree/main/packages/create-llama).
## Getting Started
First, install the dependencies:
```
npm install
```
Then check the parameters that have been pre-configured in the `.env` file in this directory.
Make sure you have set the `OPENAI_API_KEY` for the LLM.
Second, generate the embeddings of the example documents in the `./data` directory:
```
npm run generate
```
Third, run the development server:
```
npm run dev
```
Open [http://localhost:3000](http://localhost:3000) with your browser to see the chat UI.
## Configure LLM and Embedding Model
You can configure [LLM model](https://ts.llamaindex.ai/docs/llamaindex/modules/llms) and [embedding model](https://ts.llamaindex.ai/docs/llamaindex/modules/embeddings) in the [settings file](src/app/settings.ts).
## Use Case
We have prepared an [example workflow](./src/app/workflow.ts) for the agentic RAG use case, where you can ask questions about the example documents in the [./data](./data) directory.
You can start by sending an request on the [chat UI](http://localhost:3000) or you can test the `/api/chat` endpoint with the following curl request:
```shell
curl --location 'localhost:3000/api/chat' \
--header 'Content-Type: application/json' \
--data '{ "messages": [{ "role": "user", "content": "What standards for a letter exist?" }] }'
```

## Custom UI Components
For Deep Research, we have a custom component located in `components/deep_research_event.jsx`. This is used to display the results of the deep research workflow in a more user-friendly way
### Generate a new UI Component from workflow event
You can regenerate a new UI component from the workflow event schema by running the following command:
```
npm run generate:ui
```
## Use Case
We have prepared an [example workflow](./src/app/workflow.ts) for the Deep Research use case, where you can request a detailed answer about the example documents in the [./data](./data) directory.
You can start by sending an request on the [chat UI](http://localhost:3000) or you can test the `/api/chat` endpoint with the following curl request:

```
Then check the parameters that have been pre-configured in the `.env` file in this directory.
Make sure you have set the `OPENAI_API_KEY` for the LLM and the `E2B_API_KEY` for the code interpreter. You can get the E2B API key from [here](https://e2b.dev).
Second, generate the embeddings of the example documents in the `./data` directory:
```
npm run generate
```
Third, run the development server:
```
npm run dev
```
Open [http://localhost:3000](http://localhost:3000) with your browser to see the chat UI.
## Configure LLM and Embedding Model
You can configure [LLM model](https://ts.llamaindex.ai/docs/llamaindex/modules/llms) and [embedding model](https://ts.llamaindex.ai/docs/llamaindex/modules/embeddings) in the [settings file](src/app/settings.ts).
## Use Case
We have prepared an [example workflow](./src/app/workflow.ts) for the financial report generation use case, where you can request for the app to generate a financial report using the example documents in the [./data](./data).
You can start by sending an request on the [chat UI](http://localhost:3000) or you can test the `/api/chat` endpoint with the following curl request:
```shell
curl --location 'localhost:3000/api/chat' \
--header 'Content-Type: application/json' \
--data '{ "messages": [{ "role": "user", "content": "Generate a financial report that compares the financial performance of Apple and Tesla" }] }'
```
