Thank you again to @h_piedcoq, @psm, and @Sunil_Natraj for contributing to the session.

## Recording overview

The recording includes three main parts:

- **Hervé Piedcoq’s demo** (starts at 00:19 min), based on his [DataHarvest 2026 tutorial](https://github.com/herve-checkfirst/DataHarvest2026-Refine_with_llm), with a focus on data journalism workflows. Hervé spent a significant part of the demo showing name cleaning with the LLM extension. His tutorial materials are linked in the first post of this thread.

- **Parthasarathi Mukhopadhyay’s demo** (starts at 24:23 min), focused on library-specific use cases and testing different models via Ollama. His related materials are available here:

- **Community discussion** (starts at 50:15 min), including questions with Sunil Natraj, developer of the OpenRefine LLM Extension.

## Topics covered

Some of the points discussed during the session include:

- using the LLM extension for name cleaning and data journalism workflows
- testing local models through Ollama
- library metadata use cases
- using structured JSON responses so that an LLM can return multiple data points in a single answer
- including fields such as confidence scores or reasoning notes in structured outputs
- possible uses of LLMs to review reconciliation service candidates
