Building TargetV1: A Confidence-Gated Recognition Pipeline (and the Blackwell GPU Bug That Almost Stopped Me)
22+ min ago (410+ words) I Built a Recognition App That Admits When It's Not Sure. Here's What It Took. That sounds simple. It really wasn't. The first wall: hardware nobody had caught up to yet I started on a laptop with an RTX 5060. Blackwell…...
Neve - Towards a Unified Programming Model for the Complete Deep Learning Stack
13+ min ago (805+ words) Hi folks, this is No Saved DATA. I dedicate this post to describe some of the features I put in Neve to make it an expressive high-level language (close to Python/PyTorch syntax), while also allowing efficient low-level code. I…...
Eval-First RAG: Use Separate Scores to Triage Failures
31+ min ago (478+ words) Separate retrieval relevance from generation faithfulness to route RAG failures toward the right first inspection area. Tagged with rag, ai, machinelearning, testing....
Why video is the first frontier as AI learns to read the physical world
1+ hour, 6+ min ago (712+ words) With 562 million surveillance cameras already installed worldwide and two-thirds now shipping with deep-learning analytics, Lumana is betting that making existing video feeds searchable and intelligent is physical AI's fastest path to scale....
The Queen of Computer Vision and Her Kingdoms
1+ hour, 57+ min ago (393+ words) Once upon a time, in the Universe of Machine Learning, on the planet of Computer Vision, there lived a powerful queen named OpenCV. Her royal palace stood in the Kingdom of C++, where she had ruled for many years. Her…...
Prompt filters are advisory. Enforce on the execution path.
2+ hour, 3+ min ago (1514+ words) Simon Willison calls it the lethal trifecta: private data, untrusted content, and a way to exfiltrate, all in the same session. A coding agent on your laptop has all three by default. It reads your code (private data), it reads…...
Benchmarking Serverless GPUs: Modal vs RunPod vs Replicate Cold Starts (2026)
2+ hour, 37+ min ago (374+ words) Deploying open-source LLMs (like Llama-3) or real-time Whisper transcription in production often forces a difficult architectural trade-off: keep dedicated GPUs running 24/7 (expensive) or rely on serverless scale-to-zero (cold start latency penalty). To evaluate container spin-up overhead, we benchmarked median cold…...
Why Most AI Applications Fail in Production: Lessons Developers Should Know
3+ hour, 41+ min ago (667+ words) Developers can now connect powerful AI models, create interfaces, and build functional prototypes in a relatively short time. However, creating a production-ready AI system is a much bigger challenge. A prototype can demonstrate that an idea works. A production system…...
Benchmarking Real-Time Voice AI APIs: Cartesia vs Deepgram vs ElevenLabs (2026)
3+ hour, 19+ min ago (323+ words) When building conversational agents or real-time voice applications, latency is the defining metric. If Time-to-First-Byte (TTFB) exceeds 200ms, natural turn-taking breaks down and conversational interruption becomes clunky. We recently recorded and aggregated median latency and pricing metrics across the primary streaming…...
AI agents not ready to replace humans in behavioral research
3+ hour, 22+ min ago (426+ words) A new study shows that digital twins don’t respond like the individuals they were modeled after A new study suggests that behavioral scientists should use digital twins with caution. Replacing human subjects with AI surrogates, or digital twins, is on…...
