not much happened today

**Moonshot's Attention Residuals** paper introduced an input-dependent attention mechanism over prior layers with a **1.25x compute advantage** and less than **2% inference latency overhead**, validated on **Kimi Linear 48B total / 3B active**. The paper sparked debate on novelty versus prior art like **DeepCrossAttention** and Google’s earlier work, highlighting tensions in **idea novelty**, **citation quality**, and **frontier-scale validation**. **OpenAI's Codex** showed strong momentum with over **2M weekly active users**, nearly **4x growth YTD**, and **GPT-5.4** hitting **5T tokens/day** and a **$1B annualized run-rate**. Codex added subagents supporting multi-agent coding workflows. Infrastructure for coding agents matured with tools like **Context Hub / chub** supporting agent feedback loops, **AssemblyAI's skill** for Claude Code and Codex, and automated skill extraction from GitHub repos yielding **40% knowledge-transfer gains**. **LangChain** launched **LangGraph CLI** and open-sourced **Deep Agents**, recreating top coding agent workflows with planning, filesystem ops, shell access, and sub-agents.
