European Commission builds the self-hosted AI@EC platform on Haystack

After its first generative AI project, GPT@EC, a conversational AI assistant run on the Commission's own data and systems, the European Commission found it lacked a platform to build, govern and scale AI. With deepset it built the self-hosted AI@EC Platform on the Haystack Enterprise Platform. Key metrics listed are 68 builders creating AI applications, 29 Director Generals running AI pipelines and 316 pipelines in production or ready for rollout.

It is one of 60 sightings filed under Knowledge & Notes on Agent Sightings (number 3 by interest), and one of 1 involving Haystack Enterprise Platform.

How you could try it

Here is a reusable prompt, written by us in our own words, that captures the task. Paste it into Haystack Enterprise Platform or any similar agent and adjust the details to your situation.

I want an assistant that answers staff questions from our own documents and cites where each answer came from. The tool in the source case was Haystack Enterprise Platform.

Saved

Tip: Start small: run it once on a low-stakes example, read what the agent did, and only then let it run on real work.
