We’ve built North America's most capable pharmacy agents using LangChain and Elasticsearch, securing over $1M in pre-seed funding and serving pharmacy chains with over a thousand stores. I was at the Google Montreal office 2 weeks ago sharing my experiences at a genAI panel. I’d love to give a lightning talk at the Elastic and LangChain NYC Meetup on building high-accuracy agents for high-risk industries. Healthcare is a tough industry but LangChain helped us tremendously. Our journey through due diligence and navigating legacy sectors could offer valuable insights.

Earlier this month, my band did a run of shows in the Shanghai area, and there were some press clippings in Chinese that I needed to translate. I built an example application that translates the text of these clippings from Chinese to English using Doctran and uses vector search in Elasticsearch to learn more about the translated documents.

Data loading with Python in Elasticsearch.

Elasticsearch and Kibana added a new query language: ES|QL — coming with a new endpoint (_query) and a brand new syntax. It lets you refine your results one step at a time and adds new features like data enrichment and processing right in your query. And you can use it across the Elastic Stack — from the Elasticsearch API to Discover and Alerting in Kibana. But the biggest change is behind the scenes: using a new compute engine that was built with performance in mind. Join us for a quick overview and a look at syntax and internals.
