Just 2 days ago OpenAI announced structured outputs. However we can already use [@OutlinesOSS (https://x.com/OutlinesOSS) to do the same with open source models since it’s been around for a year.

Most of the issues with graphrag is that many times the less powerful local LLMs do not yield a valid json. The most notable case is with the extraction of community reports giving the notorious "KeyError: 'community'

Describe the solution you'd like

Regardless of the selected LLM the integration of Graphrag with OutlinesOSS will always output valid json when needed
