OpenAI's GPT-OSS family provides open-weight language models with explicit chain-of-thought (CoT) reasoning and a Harmony prompt format. We summarize an extensive security evaluation of GPT-OSS-20B that probes the model's behavior under different adversarial conditions. Using the Jailbreak Oracle (JO) [1], a systematic LLM evaluation tool, the study uncovers several failure modes including quant fever, reasoning blackholes, Schrodinger's compliance, reasoning procedure mirage, and chain-oriented prompting. Experiments demonstrate how these behaviors can be exploited on the GPT-OSS-20B model, leading to severe consequences.

Enterprises are creating more and more videos and using them for various informational purposes, including marketing, training of customers, partners & employees and internal communications. However, videos are considered as the blackholes of the internet because it is very hard to see what's inside them. The opaque nature of videos equally impacts end users who spend a lot of time navigating to their point of interest, leading to severe underutilization of videos as a powerful medium of information. In this talk, we will describe visual processing pipeline of VideoKen platform which includes Graph-based algorithm along with deep scene text detection to identify key visual frames in the video, FCN-based algorithm for semantic segmentation of screen content in visual frames, Transfer-learning based visual classifier to categorize screen content into different categories such as slides, code walkthrough, demo, handwritten, etc. and Algorithm to detect visual coherency and select indices from the video. We will discuss challenges and experiences in implementing/iterating on these algorithms using our experience with processing 100K video hours of content.

This question originally appeared on Quora. This means if you were to remove everything you can see and interact with in the visible universe (people, food, home appliances, planets, stars, galaxies, nebulae, etc.), there would still be 95% of the universe remaining! The result is that there is more dark matter and dark energy in the room you are currently in than normal matter. It is percolating through your body as you read this answer! The general rule is that dark matter holds galaxies together and dark energy drives the expansion of the universe. It is the ultimate tug of war. At the beginning of the universe, dark matter was much more powerful than dark energy, which is what allowed early galaxies to form. But dark energy has now taken over and is causing distant galaxies to recede from us at a rate faster than the speed of light. As you may know, no object with mass can exceed the speed of light, however there is no limit on the speed at which the spacetime medium (which ...
