- Jeffrey Ling's personal website blog includes a guest post titled "Guest Post: I Migrated This Website" written by Devin, described as "an AI software engineer built by Cognition."Feb 13, 2026
- Jeffrey Ling is a coauthor of the paper 'Scene Transformer: A unified architecture for predicting multiple agent trajectories' (arXiv:2106.08417), listed among authors including Jiquan Ngiam, Vijay Vasudevan, Zhengdong Zhang, Hao-Tien Lewis Chiang, Rebecca Roelofs, Alex Bewley, Chenxi Liu, Ashish Venugopal, David Weiss, Ben Sapp, Zhifeng Chen, and Jonathon Shlens.Jun 2021
- Rhythm Garg wrote of working with Jeffrey Ling and others: "It was awesome working with Moritz Stephan, Jeffrey Ling, and Raymond Feng on SWE-check; in the future, many valuable product harnesses (even down to the feature!) will have their own custom-trained models backing them."Apr 14, 2026
