AI weekly: OpenAI's math controversy, Meta's Muse, DeepSeek V4.1 Flash
X is still the best way I’ve found to keep up with AI. I like tweets throughout the week, then use Claude Code to pull those likes automatically and help me pull the signal out of the noise for this post (here’s how the pipeline works).
