# RAG Operations in Pixeltable

In this tutorial, we'll explore Pixeltable's flexible handling of RAG operations on unstructured text.

- **Type:** Notebook
- **Group:** Agents

## What it covers

- Creating Tables and Views
- Data Ingestion
- Experimenting with Chunking
- Further Experiments
- Computing Embeddings

## What it uses

- **Install:** `pip install pixeltable sentence-transformers spacy tiktoken`
- **Pixeltable calls:** `document.document_splitter()`, `huggingface.sentence_transformer()`, `huggingface.clip()`, `pxt.create_table()`, `pxt.create_view()`, `insert()`, `add_computed_column()`

## A look at the code

```python
from pixeltable.functions.huggingface import sentence_transformer

chunks.add_computed_column(
    minilm_embed=sentence_transformer(
        chunks.text, model_id='paraphrase-MiniLM-L6-v2'
    )
)
```
