For the back of the room: • production-grade reranking for sales data with Jev • 20x faster • 10x cheaper • 12% more accurate Are you getting it yet?
We used Jev to retrieve sales data 20x faster, 10x cheaper, and 12% more accurate than GPT-5 Mini. Every time a Rox agent answers a query, it pulls from relevant transcripts, emails, CRM notes, news, and documents. We benchmarked two ways of retrieving them: LLM-based reranking Jev classification The results speak for themselves. Jev was faster, cheaper, and more accurate. Revenue agents require thousands of points of context to understand accounts, chart relationships, and execute on sales. This research will help us serve that context with frontier-level performance for our customers.

OpenClaw deleted around 400k LOC of its own tests without much change in code coverage. Modern models just love writing tests for every tiny change, even if they aren't useful. This skill helped. github.com/openclaw/openclaw…

We redesigned the Cloudflare Blog — dark mode, cleaner UI, faster load times. What you might not know: the whole thing runs on EmDash, a new CMS built on Cloudflare Workers. We were Customer Zero. cfl.re/4xkPMhh

Following the magnitude 7.4 earthquake that struck Colombia's western region we observed a significant drop in Internet traffic across the affected areas. Connectivity in the region fell sharply immediately after the quake, especially in regions near the epicenter such as Risaralda. 📉 Monitor the region's Internet activity on Radar at radar.cloudflare.com/traffic… #Colombia #InternetTraffic #CloudflareRadar

It's good practice to listen to your users. Do you usually send out surveys or interview them?
