AI & ML — Modernizing the Facebook Groups Search to Unlock the Power of Community Knowledge

Modernizing the Facebook Groups Search to Unlock the Power of Community Knowledge

We’ve fundamentally transformed Facebook Groups Search to help people more reliably discover, sort through, and validate community content that’s most relevant to them. We’ve adopted a new hybrid retrieval architecture and implemented automated model-based evaluation to address the major friction points people experience when searching community content. Under this new framework, we’ve made tangib

Engineering — Thank You For Being a Friend

Thank You For Being a Friend

It's been one of those months, and by that, I mean one of the 663 months since I was born. This won't be a long post, because I only have two things to say. First, I'm really glad we re-ordered the GMI (Guaranteed Minimum Income) rural study counties so Mercer County, WV, my Dad's county, went first in October 2025.

Performance — Unweight: how we compressed an LLM 22% without sacrificing quality

Unweight: how we compressed an LLM 22% without sacrificing quality

Running LLMs across Cloudflare’s network requires us to be smarter and more efficient about GPU memory bandwidth. That’s why we developed Unweight, a lossless inference-time compression system that achieves up to a 22% model footprint reduction, so that we can deliver faster and cheaper inference than ever before.

AI Search: the search primitive for your agents

AI Search is the search primitive for your agents. Create instances dynamically, upload files, and search across instances with hybrid retrieval and relevance boosting. Just create a search instance, upload, and search.
