The lead item was An interview with OpenAI Chief Research Officer Mark Chen on the Hugging Face incident, slowing AI development.... Also high in the stack: Gemini 4 Argon has a 1M-token output limit, up from 64K for prior models; it initially costs $2/1M input and $10/1M... and Claude computes a nine-loop amplitude in N=4 super-Yang-Mills \ Anthropic. That combination is why this archive exists: it preserves the day's shape for AI practitioners, not just the last headline that crossed the wire.
