You Might’ve Missed
TurboQuant on Blackwell B200 — @anirudhbv_ce implemented Google Research's TurboQuant as a CUDA-native compression engine on NVIDIA's Blackwell B200. 5x KV cache compression on Qwen 2.5-1.5B with near-lossless attention scores, generating live from compressed memory. Five custom cuTile CUDA kernels including fused attention with QJL corrections, online softmax, and on-chip cache decompression. 781K views.
LLM trained on pre-1900 text rediscovers physics — @hla_michael trained an LLM from scratch exclusively on pre-1900 text to see if it could arrive at quantum mechanics and relativity. The model is small, but when given observations from landmark experiments it declared that "light is made up of definite quantities of energy" and suggested gravity and acceleration are locally equivalent. Dataset and models released as an open problem. 305K views.
mlx-vlm v0.4.3 — @Prince_Canuma ships a major update to mlx-vlm with day-0 support for Gemma 4 (vision, audio, MoE), Falcon-OCR + Falcon Perception from TII, and Granite Vision 4.0 from IBM Research. Also adds SAM 3.1 with Object Multiplex from Meta, RF-DETR detection and segmentation from Roboflow, plus TurboQuant KV cache compression and CUDA support for vision models. 984K views.
Introducing Republic — @m_adams launches Republic, a tool for monitoring what's happening in your city. Tracks political news, crime, permits, events, community groups, and more across the city and at the neighborhood level. 215K views.
EgoNav: humanoid navigation from human walking data — @KenWangWeizhuo presents EgoNav — 5 hours of a person walking around campus with cameras is all the training data needed. A humanoid robot then traverses unseen buildings, crowds, and glass walls with zero robot data and zero finetuning. Behaviors like waiting for doors, steering around glass walls, yielding to pedestrians, and re-routing around furniture all emerged from the human walking prior. 34K views.
OpenAI hiring SLAM engineers — @danfei_xu highlights that OpenAI is now hiring for SLAM (simultaneous localization and mapping) engineers — a strong signal that OpenAI is moving into robotics and spatial intelligence. Quote-tweeting @brunoeducsant who first spotted the listing. 37K views.
AI-powered hedge fund — @nvonbodungen shares that he's been building Pentamerus, a hedge fund built entirely on AI. Quote-tweeting the Pentamerus announcement. 193K views.
