Last Week in AI: Open Models, Robots, Markets
This newsletter summarizes a week of AI developments spanning policy, open models, robotics, and markets. Nvidia-backed signatories published a letter defending open-weight models while Moonshot AI released Kimi K3 weights, signaling open models' growing competitiveness. Google DeepMind released Gemini Robotics 2, extending model capabilities into whole-body robot control. Financial stress surfaced when the AI-focused hedge fund Situational Awareness liquidated public equities to Citadel after concentrated losses, and multiple large technology companies disclosed substantial data-center lease commitments. The update also highlights technical papers (e.g., Chain-of-Evidence / ScientistOne, Shieldstral) and a string of corporate moves: acquisitions, partnerships, funding rounds, and model releases that together emphasize the industry's shift from proof-of-concept to questions of distribution, embodiment, ownership, and durable monetization.
Google DeepMind's Gemini Robotics 2 release and the open-weights policy debate backed by major industry players materially affect model distribution, robotics embodiment, and industry strategy; combined with major funding, M&A, and earnings/lease disclosures, these developments have broad infrastructure and commercial implications for AI and adjacent AdTech/MarTech businesses.

Open Weights, Stateless Agents, EU AI Transparency Enforced
This Weekly Dose (25 July–2 August 2026) summarizes five industry-moving items: Moonshot AI published full weights and a technical report for its 2.8 trillion-parameter Kimi K3 model; the MCP protocol shipped a major Go SDK implementing the 2026-07-28 stateless protocol rewrite; Microsoft announced Project Perception, an agentic security system with specialist models (public preview 3 August); Article 50 of the EU AI Act began applying on 2 August, requiring user disclosure and machine-readable markings with penalties for noncompliance; and GitHub retired GitHub Models while AWS placed several first-generation AI services into maintenance for new customers. The note highlights trade-offs between connectivity and ownership, migration risk from standards and managed services, and the operational burden of provenance and compliance.
Tech Giants Lobby for Open AI Weights Amid Huge Spend
This newsletter edition covers recent AI industry developments: research from Span showing three controllable agent-use levers (prompt clarity, environment readiness, quality stewardship) that strongly affect token costs, merged code, and review cycles; a 25-company letter urging Washington to avoid restrictions on open-weight models (signatories include Nvidia, Microsoft, Meta, Palantir, Andreessen Horowitz, Y Combinator, and OpenAI); large AI-related funding and investments (Accel & ICONIQ into Paper; Atoms raising $1.7B from a16z; Humanoid and Gritt funding); and an observational study of 14,419 self-published ebooks finding significant growth in AI-authored books but lower per-title revenue. The author also promotes a free creators’ event on August 13 in San Francisco and notes broader concerns about the mismatch between enormous corporate AI spending and lobbying for freely published model weights.
Last Week in AI #335 — Models, Agents, and Industry Moves
Last Week in AI #335 is a packed industry roundup covering recent model and agent releases, product updates, legal and financial developments, and infrastructure trends. The edition flags model releases and updates (e.g., Opus 4.6, Codex 5.3, Gemini 3 variants, GLM-5, Qwen 3.5‑Plus), agent and payments infrastructure work (Mastercard/Google Verifiable Intent, Ramp Agent Cards, Stripe Machine Payments Protocol), major corporate events (Anthropic suing the U.S. Department of Defense, Mastercard’s planned BVNK acquisition), and large financial results and platform moves (NVIDIA’s $68.1B quarter, Baidu’s RMB 40B Core AI New Business). It also highlights recommender-system improvements at Meta (Kunlun) and numerous product demos and workflows showing agent-led design/code integrations. The newsletter frames these items as indicators of accelerating agentic workflows, shifting compute and inference economics, and growing productionization of AI across commerce, payments and advertising infrastructure.
