Overview

The Generators module creates synthetic Dataset objects from context documents. This is useful for bootstrapping evaluations when you don’t have real conversation data.

​
How it works

  1. A context loader reads and chunks your documents
  2. A chunk selection strategy picks which chunks to process
  3. The generator uses an LLM to create realistic QA pairs from each chunk

​
Usage

from langchain_openai import ChatOpenAI
from gaussia.generators import BaseGenerator, create_markdown_loader

model = ChatOpenAI(model="gpt-4o-mini")
generator = BaseGenerator(model=model)

loader = create_markdown_loader()
datasets = await generator.generate_dataset(
    context_loader=loader,
    source="./docs/knowledge_base.md",
    assistant_id="my-assistant",
)

​
Context loaders

​
LocalMarkdownLoader

Reads markdown files and splits them into chunks based on headers and size: 
from gaussia.generators import create_markdown_loader

loader = create_markdown_loader(
    max_chunk_size=2000,   # Max characters per chunk
    min_chunk_size=200,    # Min characters per chunk
    overlap=100,           # Overlap between size-based chunks
    header_levels=[1, 2],  # Split on H1 and H2
)

​
Custom loader

Implement BaseContextLoader for custom document sources: 
from gaussia.generators import BaseContextLoader, Chunk

class MyLoader(BaseContextLoader):
    def load(self, source: str) -> list[Chunk]:
        # Return list of Chunk objects
        ...

​
Chunk selection strategies

StrategyDescription
SequentialStrategyProcess all chunks in order (default)
RandomSamplingStrategyRandomly sample chunks multiple times
from gaussia.generators import RandomSamplingStrategy

datasets = await generator.generate_dataset(
    context_loader=loader,
    source="./docs/",
    assistant_id="my-assistant",
    strategy=RandomSamplingStrategy(n_samples=10, seed=42),
)
