Entropy of a Large Language Model output
Large language models like ChatGPT & Claude have become ubiquitous in today’s world. I visited a friend for the New years eve and was impressed by how ChatGPT was being extensively used within the family. The friend’s little kid is going to grow up in a world, where turning to large language models (LLM) for quick…

Detecting AI agent use and abuse
The key question is: Can you detect AI agent traffic on your application today? We tested multiple AI agent toolkits across high-traffic consumer sites, and the results were clear—legacy detection techniques (CAPTCHAs, IP blocking, user-agent filtering) are largely ineffective. Here’s what we found.

AI Slop Report: The Global Rise of Low-Quality AI Videos
Kapwing’s new research shows that 21-33% of YouTube’s feed may consist of AI slop or brainrot videos. But which countries and channels are achieving the greatest reach — and how much money might they make? We analyzed social data to find out.

Writing Speed-of-Light Flash Attention for 5090 in CUDA C++
In this post, I will walk through how I learned to implement Flash Attention for 5090 in CUDA C++. The main objective is to learn writing attention in CUDA C++, since many features are not available in Triton, such as MXFP8 / NVFP4 MMA for sm120. I also feel this is a natural next step after learning about matmul…

Being “Confidently Wrong” is holding AI back
The failure mode that stalls “AI for data” efforts or "AI on my APIs" efforts isn’t psychedelic hallucination—it’s confident inaccuracy: plausible answers that are wrong in subtle and costly ways.

Positional preferences, order effects, prompt sensitivity undermine AI judgments
When Large Language Models are used as judges for decision-making across various sensitive domains, they consistently exhibit unpredictable and hidden measurement biases, making their verdicts unreliable despite common prompt engineering practices.
