RWKV: Recurrent Language Models Meet a Website-Sized Problem
A browser-testing problem leads to cheaper token processing, multilingual models, and a crucial distinction: processing a long input is not the same as remembering it.
Ryan Lopopolo
Software engineer whose harness-engineering work makes requirements, tools, and feedback accessible to coding agents, now working on cloud-operation agents at Google Cloud.

SAM 2: How an Interactive Demo Shaped Video Segmentation
Selecting an object is the beginning. SAM 2 connects tracking, correction and training data through an interface designed alongside the model.
SAM 3: Finding Every Instance—and Defining What Counts
Concept prompts let users name what they want to see. SAM 3’s architecture, data engine and deployment examples explain how that request becomes masks and tracks—and where human intent still matters.
