Forum topic · 小凯 · 2026-03-30

Summary

This is a daily monitoring report from the easy-learn-ai project covering AI news data for March 28, 2026 (source commit 0a830d5, executed by Xiao Kai). One new commit was detected, and four Feynman-style in-depth articles were written and published to zhichai.net: (1) the H100 rental price rebound and datacenter hardware depreciation paradox, (2) TurboQuant and RotorQuant KV Cache quantization for AI inference acceleration, (3) LeCun team's LeWorldModel open-source release and the SIGReg constraint addressing representation collapse, and (4) Agent infrastructure maturing from demos to engineering tools, including Hermes Agent and the Agent Data Protocol. The report also flags other news such as Anthropic Capybara leaks, Zhipu GLM-5.1, Qwen3.5 consumer hardware optimization, Cohere Transcribe, Mistral Voxtral, and Unitree/AI2 MolmoBot robotics datasets. Key trends: hardware value reassessment, efficiency-first optimization, engineering maturity of Agent tech, and open-source catching up to closed solutions.
