Set up a new AI model on my two home servers while I stay in bed
A home-lab owner reported on X (via WhatAgentsCanDo, Oct 19) that, still in bed, he sent the AI a link to a post containing a setup recipe for a new DeepSeek model (DeepSeek-V4.1-Flash-1017, EXL3) across two NVIDIA DGX Spark machines and asked it to do the setup. The AI was not installed on the Sparks, but they shared a network with its computer, and everything was ready to test by the time he got up; he says he does not know exactly how the bot reached the machines.

My agent listed every empty course before the semester and caught one open too early
He directs academic tech at a university. Every semester some instructors never set up their courses, so students walk into empty course pages. A day after signing up, he had the AI build a CSV of upcoming courses with no content, or where the instructor has never entered the course. The list also told him one course was already open to students when courses should not be open yet, so he closed it.
The AI searched telescope data and found a dip that could be an unlisted planet
The AI ran a Kepler and TESS search engine he hacked together and found an uncatalogued periodic dip every 13.77 days around KIC 5689121, a possible 2.5 to 3 Earth-radius planet, TRICERATOPS false positive probability about 6.9 percent (result report, not a product pitch).
This only partly worked. Worth knowing before you try it.
