We built a thing! The Databricks Reranker is now in Public Preview. It's as easy as changing the arguments to your vector search call, and doesn't require any additional setup. Read more: www.databricks.com/blog/reranki...

Reranking in Mosaic AI Vector Search for Faster, Smarter Retrieval in RAG Agents

Boost RAG agent quality with reranking—deliver more relevant answers in less time with a single parameter in Mosaic AI Vector Search.

The transformer was invented in Google. RLHF was not invented in industry labs, but came to prominence in OpenAI and DeepMind. I took 5 of the most influential papers (black dots) and visualized their references. Blue dots are papers that acknowledge federal funding (DARPA, NSF).

LongEval is turning three this year! This is a Call for Participation to our CLEF 2025 Lab - try out how your IR system does in the long term. Check the details on our page: clef-longeval.github.io

The PhD is pretraining. Interview prep is alignment. Take this to heart. :)

We have updated #nocha, a leaderboard for reasoning over long-context narratives 📖, with some new models including #Gemini 2.5 Pro which shows massive improvements over the previous version! Congrats to #Gemini team 🪄 🧙 Check 🔗 novelchallenge.github.io for details :)

Perhaps the most misunderstood aspect of retrieval: For a context to be relevant, it is not enough for it to improve the probability of the right answer.

Somehow my most controversial take of 2025 is that agents relying on grep are a form of RAG.

It was a real pleasure talking about effective IR approaches with Brooke and Denny on the Data Brew podcast. Among other things, I'm excited about embedding finetuning and reranking as modular ways to improve RAG pipelines. Everyone should use these more!

We're probably a little too obsessed with zero-shot retrieval. If you have documents (you do), then you can generate synthetic data, and finetune your embedding. Blog post lead by @jacobianneuro.bsky.social shows how well this works in practice. www.databricks.com/blog/improvi...

Improving Retrieval and RAG with Embedding Model Finetuning

Fine-tune embedding models on Databricks to enhance retrieval and RAG accuracy with synthetic data—no manual labeling required.

I do want to see aggregate stats about the model’s generation and total reasoning tokens is perhaps the least informative one.

"All you need to build a strong reasoning model is the right data mix." The pipeline that creates the data mix:

Using 100+ tokens to answer 2 + 3 =

It’s pretty obvious we’re in a local minima for pretraining. Would expect more breakthroughs in the 5-10 year range. Granted, it’s still incredibly hard and expensive to do good research in this space, despite the number of labs working on it.

I’m being facetious, but the truth behind the joke is that OCR correction opens up the possibility (and futility) of language much like drafting poetry. For every interpreted pattern for optimizing OCR correction, exceptions arise. So, too, with patterns in poetry.

Reasoning is fascinating but confusing. Is reasoning a task? Or is reasoning a method for generating answers, for any task?

Reflections on NeurIPS: There's always a big theme people seem to be preoccupied with. This year, it was the continuation of scaling/progress. Will it continue? What will the next generation of models hold? I even got to sass Dylan Patel (not on bsky) over it. Here are my personal thoughts 🧵

Today we'll be presenting the Tutorial on Retrieval-Enhanced Machine Learning (REML). Come by to learn about the emerging design patterns in this space and see how to use retrieval beyond RAG. In collaboration w/ the amazing @841io.bsky.social @teknology.bsky.social Alireza Salemi and Hamed Zamani.
