The Asymmetry Week

Open Weights, Code Review, and Agent Identity

US curbs pushed buyers to open-weight models, two reports argued AI coding's hard part is no longer writing it, and agents got identities of their own.

Model Halts, Agentic Git, and Open Reasoning

A US order halted Anthropic's new models, AI agents rewrote Git in Rust, and Hugging Face open-sourced a DeepSeek-R1 reasoning recipe.

Coding Costs, Apple on Gemini, and Open-Weight Gains

AI coding tools may cost providers 10x what users pay, Apple rebuilt Siri on Google's Gemini, and DeepSeek's V4 reportedly beat GPT-5.5 on precision.

Chips, Code, and the Edge

Memory drives most of your inference bill, a cost-optimisation layer starts forming around developer tools, and agentic models reach consumer silicon.

Agents and Zero-Days

OpenAI and Notion ship agent platforms while Google confirms the first AI-driven zero-day exploit. This week's AI briefing for engineering leads and security architects.
