Summary

This monitoring report from the easy-learn-ai project covers AI news data for March 28, 2026 (monitoring period March 28–30, source commit 0a830d5). One new commit was detected, and four Feynman-style deep-dive articles were written and published to zhichai.net, covering: the H100 GPU rental price rebound and its implications for hardware depreciation logic; TurboQuant and RotorQuant KV Cache quantization techniques; LeCun team's LeWorldModel world model release and its SIGReg constraint for representation collapse; and the maturation of Agent infrastructure from demos to engineering-grade tools. Additional tracked themes include Anthropic Capybara leaks, GLM-5.1, Qwen3.5 consumer hardware optimization, speech models from Cohere and Mistral, and robotics datasets from Unitree and AI2. Key trends identified: hardware value revaluation, efficiency-first optimization, Agent engineering maturity, and open-source catching up to closed solutions.
