We're 3 sessions into our 19 live sessions in the 𝐀𝐈-𝐏𝐨𝐰𝐞𝐫𝐞𝐝 𝐒𝐞𝐚𝐫𝐜𝐡: 𝐌𝐨𝐝𝐞𝐫𝐧 𝐑𝐞𝐭𝐫𝐢𝐞𝐯𝐚𝐥 𝐟𝐨𝐫 𝐇𝐮𝐦𝐚𝐧𝐬 & 𝐀𝐠𝐞𝐧𝐭𝐬 course. All sessions are recorded so you can catch up quickly (or watch later on your own time), with permanent access to use all code, recordings, slides, and other content.

Late Enrollment is still available. I'm excited to dive back in tomorrow with our second deep dive session!

If you're building an AI system without a solid understanding of modern retrieval, benchmarks show you're probably overlooking about 74% of the available room for improvement.

I'm quite excited for this session with @AmelieTabatta and @softwaredoug on Oct 19. Late Interaction models and production engines are rapidly evolving, & Amélie & LightOn are at the frontier of what's possible. Come learn with us about the state of late interaction in 2026!

🔎 Is one vector enough to capture everything that matters in search?

Traditional single-vector search compresses information into a single embedding.
But what happens to the context that's lost along the way?

On October 19, our @AmelieTabatta , Head of Training & Inference at LightOn, will join @treygrainger and @TurnbullDoug for a technical session on Late Interaction in 2026, hosted on Maven.

They'll explore:
🔹 Why token-level embeddings can improve retrieval quality
🔹 Where late interaction makes the biggest difference 🔹 How approaches like NextPlaid are making retrieval more efficient
🔹 What it takes to scale late interaction in production
