Super exciting win for Agentic Search and Late Interaction! 🧬 GPT-5 + Reason-ModernColBERT (150M) reaches ~88% accuracy with an average of ~13 search calls. For reference, when BrowseComp-Plus was published in August 2025, the max accuracy reported was ~70% using GPT-5 + Qwen3-Embed-8B, using ~22 search calls. Searching with reasoning 🤖💭is a beast. 🔥 This is a huge evangelist for semantic search and Late Interaction models are particularly shining thanks to their effectiveness at long input modeling with fine-grained similarity scores. 🛠️ Congratulations @antoine_chaffin and team! 🎉

BrowseComp-Plus, perhaps the hardest popular deep research task, is now solved at nearly 90%... ... and all it took was a 150M model ✨ Thrilled to announce that Reason-ModernColBERT did it again and outperform all models (including models 54× bigger) on all metrics

By providing LLMs with 🗺️ •metadata about the collections in the database and their schemas • values of attributes and their distributions • initial search results ... We get much better Query Understanding! This leads to more effective Search, Question Answering, Research, and other AI systems. 🚀

Hey everyone! I am super excited to publish a new episode of the Weaviate Podcast with Doug Turnbull (@softwaredoug) and Trey Grainger (@treygrainger) on AI-Powered Search! 🎉 Doug and Trey are both tenured experts in the world of search and relevance engineering. I am beyond grateful for this opportunity to host them on the Weaviate Podcast and discuss all things under the sun with AI and Search! This one is packed with information! 🧠 Covering designing search experiences, types of search, user interfaces for search, filters, the nuances of agentic search, using popularity as a feature in learning to rank... and I loved learning about their pioneering ideas on Wormhole Vectors and Reflected Intelligence!

@lateinteraction Yeah, I know people getting crazy offers right now, and not just from the labs. We're teaching this skillset in our AI Search course to many top engineers (see company logos below). Just kicked off the second cohort (w/ late registration still available) aipoweredsearch.com/live-course

I was deep in the newborn trenches🍼as @a1zhang and @lateinteraction took the AI world by storm with RLMs and missed out a bit on these discussions, hoping to catch up! 🧩🔥 Really happy that @softwaredoug brought up RLMs in our discussion of AI-Powered Search, describing how LLMs can write code to search over their context as a Python variable. 👇

Adding a Popularity Feature ✨ to Search Ranking is trickier than you may think. @softwaredoug lays out the feedback loop problem, popular results get boosted, get more clicks, get boosted further... ♻️ He then introduces two concrete solutions: (1) holdout traffic that doesn't receive the popularity treatment, and (2) active learning that finds "wide-open, gaping holes" in training data. 🧠

WORMHOLE VECTORS! 🔥 In Hybrid Search, searchers such as BM25 and Vector Search run independently, produce separate result sets, and get merged... Introducing ... 🥁 ... Wormhole Vectors! 🔥 Instead of merging orthogonal results, traverse between the vector spaces. Run a lexical search, pool the matching documents' dense vectors, and search the dense space from that point. 🌀 Hybrid search runs two queries and hopes the right answer was in one of them. Wormhole vectors let you traverse between the spaces instead. 🗺️

"Purple Mattress", is that a color or a brand? A memorable and fun example of query disambiguation in action. Search the index for "Purple Mattress", aggregate the entities in the results, and ask an LLM to classify which meaning the user intended. x.com/CShorten30/sta…

Is grep all that Agents need for search? 🤔 In this clip, Doug explains why simple lexical tools like grep work so well for agents, the transparent input-output relationship lets the agent reason about why results matched, adjust its strategy, and plan its next query. 👇
