Why HN links it
Diabettech covers diabetes technology such as CGM devices (Dexcom G6, Libre, Stelo) and a study of LLM carb counting. HN commenters cite its device posts and discuss the AI study.

What Hacker News says?
According to [1] the G6 at least measures skin temperature, but it is unclear if it measures air temperature as well (which the Libre does). I also found a reddit thread [2] that indicates it's quite common to get drastic changes in readings during hot showers with Dexcom (probably G6 version based on the date), so you might be an outlier in that regard.

HN discussion>> But the author just took pictures of food & expected a realistic response? Is this genuinely what amounts to a study in AI? The aim of the study was to understand the variation in results returned by models and how that could cause risks for patients using those models. The main result was measuring within-model variation. From the pre-print ( https://www.diabettech.com/wp-content/uploads/2026/04/diabet... ): We…

on “He asked AI to count carbs 27000 times. It couldn't give the same answer twice”Let's start with the wrong title: > I Asked AI to Count My Carbs 27,000 Times. It Couldn’t Give Me the Same Answer Twice. If you look at the image https://www.diabettech.com/i-asked-ai-to-count-my-carbs-2700... it clearly shows some repeated values. I guess AI like multiples of 5 or 10 or something. It would be nice to look at the raw tables. > A cheese sandwich on a plate. Here’s one that should be easy. Two slices…

on “He asked AI to count carbs 27000 times. It couldn't give the same answer twice”I tried asking LLMs about food before. They all say "I can't tell for certain, but this is an estimate based on the ingredients I can spot/infer/guess". You need to write a specific prompt to avoid any warnings. Of course a lot of people don't know what limitations LLMs have, so there's some value to a blog post about it, but it's not as black-and-white as the article might suggest with its graphs. The prompt (docum…
