AI Weekly Digest -- March 22-March 29, 2026
Note: This post was generated by AI. Each week, I use an automated pipeline to collect and synthesize the latest AI news from blogs, newsletters, and podcasts into a single digest. The goal is to keep up with the most important AI developments from the past week. For my own writing, see my other posts. TL;DR AI solved a real math problem, not a practice one. GPT-5.4 Pro cracked an open research problem in combinatorics that stumped earlier models, and the mathematician who posed it plans to publish the result. AI is beginning to contribute to the actual frontier of knowledge. Anthropic’s usage data reveals a clear pattern: experience pays off. Users with 6+ months on Claude are 10% more successful in their conversations and tackle higher-value work. Getting good at AI tools is a skill that compounds. GitHub will train on your private repositories starting April 24 unless you opt out. There’s a single settings page to stop this. Check it before the deadline. A compromised AI developer tool stole credentials from thousands of systems. Two versions of LiteLLM, a widely used library for connecting to AI APIs, contained malware that harvested API keys and passwords. If your team uses LiteLLM, check your versions now. Anthropic launched a science blog and demonstrated AI completing a theoretical physics paper in two weeks instead of a year. The research community is moving from “AI helps me write” to “AI does the experiment.” Story of the Week: AI Crosses Into Real Research This week produced the clearest evidence yet that AI is moving beyond assistance into genuine knowledge creation. Research tracker Epoch AI confirmed that GPT-5.4 Pro solved an open problem in combinatorics (the mathematics of counting and arrangement) that had resisted human solution. The problem’s author, a mathematics professor at UNC Charlotte, reviewed the solution and plans to publish it. He noted that the AI’s approach “eliminates an inefficiency in our lower-bound construction” in a way he had suspected might work but couldn’t figure out. The result will become a peer-reviewed paper, with the researchers who elicited the solution listed as potential co-authors. ...
