Microsoft Publishes Provisional Limits On Future Models

Microsoft issued a provisional code of conduct on September 14 that sets limits on what its future AI models will do, including refusing requests tied to weapons manufacturing, dangerous substances, unhealthy eating, violence, and sexually explicit content. The company says it will take outside input before...

World

North Korea staged a combined live-fire exercise pairing missiles and artillery with drones on Monday, a mixed-salvo format analysts read as a rehearsal for saturating South Korean and US air defenses with cheap unmanned systems.

Markets

The US 10-year Treasury yield broke through 5%2 on Monday, all three major New York indexes closed lower, Germany's 10-year Bund hit a 15-year high, and Seoul's KOSPI fell 225.543 points, or 3.26%1, to 6684.374 as foreign and institutional investors dumped chip stocks, even as the sentiment gauge still reads Greed.

Wild Card

Nvidia sits on both sides of today's tape: it is restricting frontier model use inside its own operations over data concerns days after announcing a joint supply-chain AI system with Palantir, while chip stocks led the KOSPI selloff in Seoul.

Today's Focus

What else the day turns on.

01

Enterprise Buyers Draw Data Lines

Palantir and Nvidia are restricting how frontier AI models can be used inside their operations because of concerns about where sensitive data ends up, per The Information. The restrictions come days after the two announced a joint supply-chain AI system, which suggests even companies selling AI to enterprises are wary of feeding their own data into someone else's model. Expect procurement teams elsewhere to cite this precedent.

02

Yields, Chips, And Pyongyang

A 5%2 US 10-year yield and a 15-year high in German Bunds pulled all three New York indexes lower, and Seoul absorbed the hardest hit with a 3.26%1 KOSPI drop driven by chip selling. The same Monday, North Korea paired missiles and artillery with drones in a live-fire display it called proof of huge destructive power. For Korean equities, rate pressure and security risk are now moving in the same direction on the same day.

Productivity Free one reading session, most of it waiting on a 2.97 GB model download

Skim Recap

Flick past 4,000 pixels of an essay and a Gemma 4 model running on your own GPU hands you back exactly that stretch, with no page text ever leaving the browser.

A 2.97 GB model download and a 22 GB disk requirement are the entry fee, and that single fact decides whether this belongs on your machine. Pay it and you get something no cloud summarizer offers: recaps scoped to the exact scroll you just made, an Explain button for undefined jargon, and zero account, API key, or hosted server. Heavy readers of long documentation on a WebGPU-capable laptop should install it today; anyone on a thin machine or who wants search-results summaries should wait for a later release.

Ramen Aura 1.0 gives Unity and Unreal developers an agent with persistent project memory; hand it one Blueprint task first

Ramen Aura 1.0 is a development agent for Unity and Unreal Engine that promises faster Blueprint generation, memory that persists across sessions, and multi-project support. Start with a bounded Blueprint you already know how to write, then diff its output against yours before letting it touch shared project files. The persistent memory is the feature to test: check whether it remembers your naming conventions on the second day, not the first.

LINE Yahoo Agent i adds a task mode that watches keywords, price drops, and local events on a schedule

The new task feature in LINE Yahoo's Agent i runs continuous monitoring jobs, such as news on a keyword, a price threshold, or events near you, and notifies on a schedule instead of on demand. Set one job with a hard trigger (a specific price, a specific term) rather than a vague topic, so you can judge precision after a week. If it fires more than you read, tighten the trigger before adding a second job.

Botric AI pitches a conversational agent for customer service; pilot it on one intent and measure containment

Botric AI Agent, listed on FutureTools, positions itself as a customer service agent that handles conversations end-to-end. Pick a single high-volume intent such as order status or password reset, route only that traffic to it, and track containment rate and escalation quality for two weeks. A broad rollout hides failure modes that a single intent exposes in days.

Paper of the day

Beyond Training: A Feasibility Taxonomy for Inference-Time AI Governance

Samar Ansari · arXiv 2026-09-09

Compute governance today is a governance of training: the thresholds, reporting requirements, and frontier-AI regimes now in force attach to training compute and treat the trained model as the regulatory unit.

Third, where vendor implementations diverge architecturally (E2, V7) we rate against the most defensive available architecture. The architectural-diversity finding itself is treated in Section 4.5; here we accept that an attacker can choose the weakest vendor...

THE DOJO · BUILD TODAY

Write your own refusal list before a vendor writes it for you

  1. 01

    Draft a one-page refusal policy. Copy the shape of Microsoft's provisional code of conduct and list the categories your product will decline outright, from weapons manufacturing to explicit content. Put it in the repo so it is versioned, not remembered.

  2. 02

    Map where your prompts actually land. Palantir and Nvidia are restricting internal frontier model use over data destination fears. Run the same audit: for each integration, name the provider, the retention window, and the region, then flag anything you cannot answer.

  3. 03

    Give one agent a single narrow job. Hand Ramen Aura 1.0 exactly one Blueprint task in Unity or Unreal, or pilot Botric AI on one customer service intent and measure containment before you widen scope.

The Bottom Line

Self-regulation arrived before the regulators did

Microsoft publishing limits, Palantir and Nvidia restricting internal use, and OpenAI pushing its listing further out are the same move read from three seats. The constraint is no longer capability, it is provenance: who can say where the data went and what the model refused. Builders who can answer that in writing will close enterprise deals that capability demos no longer win. Start with the refusal list and the data map, because both will be asked for by the end of the quarter.

R
Reported: the figure is carried as published by the linked source and was not independently corroborated.
E
Estimated: the figure is approximate or hedged, either in the source or by the stat gate.

Method names the computation path behind the row, from a closed vocabulary: as published, yfinance close, 03B search corroboration, 04R dossier scoring, not recorded.

A figure is money, a percentage, a spelled magnitude, a multiple, a rate carrying its unit, a score over its denominator, a thousands separated number or an index close. Bare integers and years are not counted, so a phrase like "over 100 integrations" carries no mark. A chart's own scale line is the axis of the level above it and is counted once, with that level.
