Save $$$ with batch mode

Providers like OpenAI and Anthropic offer batch mode, which allows you to upload a bunch of prompts to be processed asynchronously, for lower costs (typically 50%). However, these APIs are often very cumbersome to manage:

• You typically have to prepare your batch file, upload it, and poll for responses periodically.

• Large datasets will typically not fit in a single batch due to batch size limits, and so you will need to split your dataset into mutiple smaller batches, increasing the complexity you need to manage.

With Curator, you only need to toggle a single flag to save $$$, without any headache!

Using batch mode

Let's look at a simple example of reannotating instructions from the WildChat dataset with new responses from gpt-4o-mini.

First, we need to load the WildChat dataset using HuggingFace:

from datasets import load_dataset

dataset = load_dataset("allenai/WildChat", split="train")
dataset = dataset.select(range(3_000))  # Select a subset of 3,000 samples

We then create a new LLM class and apply to dataset. All you need to do to enable batching is setting batch=True when initializing your LLM object, and you're done!

from bespokelabs import curator

class WildChatReannotator(curator.LLM):
    """A reannotator for the WildChat dataset."""

    def prompt(self, input: dict) -> str:
        """Extract the first message from a conversation to use as the prompt."""
        return input["conversation"][0]["content"]

    def parse(self, input: dict, response: str) -> dict:
        """Parse the model response along with the input to the model into the desired output format."""
        instruction = input["conversation"][0]["content"]
        return {"instruction": instruction, "new_response": response}
        
# Initialize the reannotator with batch processing
reannotator = WildChatReannotator(
    model_name="gpt-4o-mini",
    batch=True,  # Enable batch processing
    backend_params={"batch_size": 1_000},  # Specify batch size
)

reannotated_dataset = reannotator(dataset)

Supported Models

Currently, we only support batch mode for OpenAI and Anthropic models, but feel free to tell us which providers you want us to add support for, or send a PR if you want to contribute!
