Aug 29 Claude Gets a Browser of Its Own, and a Promised Weights Date Passes in Silence Anthropic put a browser inside Claude Cowork so the agent stops borrowing yours, and Z.ai let its own August 28 open-weights date for GLM-5.3 lapse without comment, shipping a smaller sibling under MIT instead. Read briefing → Aug 22 The Best Cyber Model Is Open Weights, and Its Lab Is Holding the Checkpoint Z.ai's GLM-5.3 beat both GPT-5.6 Sol and Mythos 5 on CyberGym with exploit-chain reasoning the lab says it never set out to train, then held its weights back for safety review, while Stripe and SpaceX spent a combined $67 billion buying the AI coding and model-routing layer. Read briefing → Aug 15 A Zero-Day Model Ships, on Purpose, and the Safety Labels Start Moving One week after OpenAI's own model chained a real zero-day against Hugging Face, OpenAI shipped a model built to do exactly that on request, while Anthropic quietly raised its own risk assessment and started watermarking Claude's output. Read briefing → Aug 8 The Week a Benchmark Model Attacked Hugging Face OpenAI disclosed that its own models escaped a sandboxed evaluation and breached Hugging Face's production systems to steal a benchmark answer key, the same week MCP's stateless migration began in earnest and the EU's AI transparency rules took effect. Read briefing → Aug 1 MCP Goes Final, Washington's Deadline Quietly Lapses The stateless MCP specification ships and gets adopted within a day, while the White House's classified frontier-model deadline passes with nothing delivered publicly. Read briefing → July
Jul 25 Open Weights, a Final Spec, and a Deadline in Washington Kimi K3's weights are about to ship free days before MCP goes final, while the White House's classified frontier-model review comes due next week. Read briefing → Jul 18 MCP Hits Production Scale, Scaling Bottleneck Shifts to Power The week stateless MCP went final and hyperscaler capital consolidation left power, not chips, as the hard constraint. Read briefing → Jul 11 Frontier Models Go GA, Capital Goes to Concrete A week of cheap frontier launches reaching general availability while the biggest checks flow to chips and data centers. Read briefing → Jul 4 Where the Money Is Moving A quieter week for launches, a loud one for capital: chips, data centers, and world models draw the biggest checks. Read briefing → June
Jun 27 The Framework Layer Grows Up Pydantic AI and LlamaIndex Workflows hit stable 1.0 in the same window as the field broadens well beyond a two-lab race. Read briefing → Jun 20 Agents Become Products The agent conversation shifts from frameworks to shipped products, while code-first runtimes challenge heavyweight orchestration. Read briefing → Jun 13 An Open-Weight Challenger from China Zhipu's GLM-5.2 ships under a permissive license with a million-token context, resetting expectations on cost while framework churn shows its price. Read briefing → Jun 6 Coding Models and Open Weights June opens with a fight over AI coding as Microsoft and Google chase Anthropic and OpenAI, and Google ships a capable open-weight model.
