### Overview

Bespoke Curator makes it very easy to create high-quality synthetic data at scale, which you can use to finetune models or use for structured data extraction at scale.

Bespoke Curator is an open-source project:
* That comes with a rich Python based library for generating and curating synthetic data.
* A Curator Viewer which makes it easy to view the datasets, thus aiding in the dataset creation.
* We will also be releasing high-quality datasets that should move the needle on post-training.

### Key Features

1. **Programmability and Structured Outputs**: Synthetic data generation is lot more than just using a single prompt -- it involves calling LLMs multiple times and orchestrating control-flow. Curator treats structured outputs as first class citizens and helps you design complex pipelines.
2. **Built-in Performance Optimization**: We often see calling LLMs in loops, or inefficient implementation of multi-threading. We have baked in performance optimizations so that you don't need to worry about those!
3. **Intelligent Caching and Fault Recovery**: Given LLM calls can add up in cost and time, failures are undesirable but sometimes unavoidable. We cache the LLM requests and responses so that it is easy to recover from a failure. Moreover, when working on a multi-stage pipeline, caching of stages makes it easy to iterate.
4. **Native HuggingFace Dataset Integration**: Work directly on HuggingFace Dataset objects throughout your pipeline. Your synthetic data is immediately ready for fine-tuning!
5. **Interactive Curator Viewer**: Improve and iterate on your prompts using our built-in viewer. Inspect LLM requests and responses in real-time, allowing you to iterate and refine your data generation strategy with immediate feedback.

### Installation

```bash
pip install bespokelabs-curator
```

### Usage

```python
from bespokelabs import curator
from datasets import Dataset
from pydantic import BaseModel, Field
from typing import List

# Create a dataset object for the topics you want to create the poems.
topics = Dataset.from_dict({"topic": [
    "Urban loneliness in a bustling city",
    "Beauty of Bespoke Labs's Curator library"
]})

# Define a class to encapsulate a list of poems.
class Poem(BaseModel):
    poem: str = Field(description="A poem.")

class Poems(BaseModel):
    poems_list: List[Poem] = Field(description="A list of poems.")


# We define a Prompter that generates poems which gets applied to the topics dataset.
poet = curator.Prompter(
    # `prompt_func` takes a row of the dataset as input.
    # `row` is a dictionary with a single key 'topic' in this case.
    prompt_func=lambda row: f"Write two poems about {row['topic']}.",
    model_name="gpt-4o-mini",
    response_format=Poems,
    # `row` is the input row, and `poems` is the `Poems` class which 
    # is parsed from the structured output from the LLM.
    parse_func=lambda row, poems: [
        {"topic": row["topic"], "poem": p.poem} for p in poems.poems_list
    ],
)

poem = poet(topics)
print(poem.to_pandas())
# Example output:
#    topic                                     poem
# 0  Urban loneliness in a bustling city       In the city's heart, where the sirens wail,\nA...
# 1  Urban loneliness in a bustling city       City streets hum with a bittersweet song,\nHor...
# 2  Beauty of Bespoke Labs's Curator library  In whispers of design and crafted grace,\nBesp...
# 3  Beauty of Bespoke Labs's Curator library  In the hushed breath of parchment and ink,\nBe...
```
Note that `topics` can be created with `curator.Prompter` as well,
and we can scale this up to create tens of thousands of diverse poems.
You can see a more detailed example in the [examples/poem.py](https://github.com/bespokelabsai/curator/blob/mahesh/update_doc/examples/poem.py) file,
and other examples in the [examples](https://github.com/bespokelabsai/curator/blob/mahesh/update_doc/examples) directory.

To run the examples, make sure to set your OpenAI API key in 
the environment variable `OPENAI_API_KEY` by running `export OPENAI_API_KEY=sk-...` in your terminal.

See the [docs](https://docs.bespokelabs.ai/) for more details as well as 
for troubleshooting information.

## Bespoke Curator Viewer

To run the bespoke dataset viewer:

```bash
curator-viewer
```

This will pop up a browser window with the viewer running on `127.0.0.1:3000` by default if you haven't specified a different host and port.


Optional parameters to run the viewer on a different host and port:
```bash
>>> curator-viewer -h
usage: curator-viewer [-h] [--host HOST] [--port PORT] [--verbose]

Curator Viewer

options:
  -h, --help     show this help message and exit
  --host HOST    Host to run the server on (default: localhost)
  --port PORT    Port to run the server on (default: 3000)
  --verbose, -v  Enables debug logging for more verbose output
```

The only requirement for running `curator-viewer` is to install node. You can install them by following the instructions [here](https://nodejs.org/en/download/package-manager).

For example, to check if you have node installed, you can run:

```bash
node -v
```

If it's not installed, installing latest node on MacOS, you can run:

```bash
# installs nvm (Node Version Manager)
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.0/install.sh | bash
# download and install Node.js (you may need to restart the terminal)
nvm install 22
# verifies the right Node.js version is in the environment
node -v # should print `v22.11.0`
# verifies the right npm version is in the environment
npm -v # should print `10.9.0`
```
