A plain-English briefing on what changed in AI this week. In about 10 minutes, catch up on new models and products, major company news, funding, policy and safety, useful tools, and the research that matters. Each edition connects the stories, ranks what matters most, and marks every item as confirmed or reported. Published every week.
OpenAI's escaped cyber evaluation turns the harness into the week's security boundary. Gemini Flash, Presence, Health, AMD's Anthropic compute partnership, and the open-weights policy fight map the product, money, and policy layer; ten papers connect behavior maps, executable skills, programmatic memory, hidden workspaces, completeness, structured-output drift, memory attacks, 2D text, and robot fast weights.
edition #4 · Jul 19, 2026Kimi K3 and Thinking Machines' Inkling split the open-weight frontier between scale and customizability, while WANDR exposes the limits of evidence-heavy research agents. Ten papers connect self-improvement, metacognition, routing, matched-budget harness evaluation, failure tracing, filtered sabotage monitoring, distribution-matching RL, interactive worlds, and cross-embodiment robotics.
edition #3 · Jul 12, 2026Three flagships on one Thursday — GPT-5.6 goes GA (Sol/Terra/Luna), SpaceXAI's "Opus-class" Grok 4.5 at $2/$6, and Meta starts charging with Muse Spark 1.1 — while the research converges on the orchestration layer: The Harness Effect's 41% cost cut with models held constant, Verification as a Scaling Axis, ReContext, Oxford's failure taxonomy (scaffolding ≠ robustness), Always-On Agents' durable-state survey, HOLA, and Puzzle-75B.
edition #2 · Jul 5, 2026The whole week in AI: the frontier's center of gravity moves (Claude Sonnet 5 ships as the agentic free default; Anthropic reportedly past OpenAI; Fable 5 returns), the money into physical/agentic AI, policy, and the ten research papers threaded around one throughline — the evaluator is the load-bearing part and freezing it kills progress (Red Queen Gödel Machine, Verification Horizon, RLMF, Paper Assistant Tool), with self-evolving code reaching robots and chips (ASPIRE, HORIZON).
edition #1 · Jun 25, 2026The whole week in AI: the lead story (GPT-5.6's system card going "High" on cyber + biology), models & releases (Sakana Fugu, GLM-5.2 open weights), business & funding (the inference megarounds), policy & safety, the ten research papers, tools & open source, and a ranked "what matters most."
