💬 Summary

19th of September 2025 OpenAI recently released their open-weights model, and here we'll show how that inevitably leaks some information about their model training stack. On the way, we'll show that GPT-5 was trained on phrases from adult websites. What data does OpenAI train their models on? That is a well-protected trade secret of course, one with vested interest for the answer, and yet OpenAI inevitably leaked some information about it with their open-weights model release GPT-oss. While GPT-oss's weights are openly available, the sources of training data are not clearly described in the model card. It is stated that GPT-oss was trained on a "text-only dataset with trillions of tokens, with a focus on STEM, coding, and general knowledge"....

💬 Summary

AI models often produce false outputs, or "hallucinations." Now OpenAI has admitted they may result from fundamental mistakes it makes when training its models. The admission came in a paper [PDF] published in early September, titled "Why Language Models Hallucinate," and penned by three OpenAI researchers and Santosh Vempala, a distinguished professor of computer science at Georgia Institute of Technology. It concludes that "the majority of mainstream evaluations reward hallucinatory behavior." Language models are primarily evaluated using exams that penalize uncertainty The fundamental problem is that AI models are trained to reward guesswork, rather than the correct answer. Guessing might produce a superficially suitable answer. Telling users your AI can't find an answer is less satisfying. As a test case,...

💬 Summary

Hello HN,

I have been an avid user of Linux for a few years and have always wanted to make a contribution to the ecosystem. This is my first standalone contribution.

GNOME Speech2Text is a Shell extension that uses OpenAI’s Whisper automated speech recognition to let you dictate via microphone and have your words transcribed.

Given how much vibe coding I do these days, this extension has made my development with various tools much faster.

I learned a lot building it and got great feedback publishing it in the extensions store.

If you try it, I’d appreciate any critique or suggestions for improvements.
