- Type: Explainer

At the AI Safety Summit, Dario Amodei explains why rapid AI progress makes dangerous capabilities difficult to predict and motivates Anthropic’s Responsible Scaling Policy (RSP). The policy combines AI safety levels (ASLs), modeled loosely on biological safety levels, with recurring tests for dangerous capabilities along the compute scaling curve. ASL-2 covers current models and calls for model cards, external red-teaming, and strong security, while ASL-3 would require unusually strong protection against weight theft and safeguards preventing operationally useful CBRN information; ASL-4 adds escalated misuse and autonomous-system risks. Amodei also describes executive involvement, integrating RSP deadlines into product and research planning, board and external accountability, and the goal of refining company policies into regulatory testing and auditing regimes.

### [Prompting Claude's long context window](https://yomu.fyi/post/prompting-claude-s-long-context-window.md)
- Company: [Anthropic](https://yomu.fyi/company/anthropic.md)
- Published: Sep 9, 2026
- Type: Benchmark

An evaluation of Claude’s 100,000-token context window tests prompting techniques for recalling specific information from long documents. Researchers built randomized collages from sections of a July 13 government document, using Claude-generated multiple-choice questions and filtering out questions it could not answer from the source passage alone. They compared a baseline with unrelated examples, dynamically selected contextual examples, and two or five examples, each with or without a scratchpad that instructed Claude Instant 1.2 to extract relevant quotes across roughly 70K and 95K token contexts. Scratchpads and contextual examples generally improved performance, with more examples performing better, although recall could decline when the answer passage was at the end. For Claude 2, the best prompting strategy raised performance from 0.939 to 0.961, a reported 36% reduction in errors; reproducible code was released in the Anthropic Cookbook.

### [An AI policy tool for today: Invest in NIST](https://yomu.fyi/post/an-ai-policy-tool-for-today-invest-in-nist.md)
- Company: [Anthropic](https://yomu.fyi/company/anthropic.md)
- Published: Sep 9, 2026
- Type: Problem & solution

Effective AI policy depends on accurately describing and quantifying systems’ capabilities and risks, but widely agreed methods for comprehensive assessment remain lacking. The proposal calls for ambitious federal funding for NIST to expand its AI measurement and standards work, building on efforts including the Face Recognition Vendor Test and AI Risk Management Framework. Additional resources could support standardized measurement techniques and community infrastructure such as testbeds for open-ended systems, with Anthropic recommending a $15 million increase over FY 2023, inclusive of NIST’s requested $5 million increase. The post presents this as a “shovel-ready” complement to internal controls, independent audits, and public-interest regulation. It argues that rigorous evaluation could identify risks before deployment, improve public trust and governmental confidence, and create incentives for safer innovation.

### [What we learned mapping a year’s worth of AI-enabled cyber threats](https://yomu.fyi/post/what-we-learned-mapping-a-year-s-worth-of-ai-enabled-cyber-threats.md)
- Company: [Anthropic](https://yomu.fyi/company/anthropic.md)
- Published: Sep 8, 2026
- Type: Benchmark

An analysis of 832 accounts banned for malicious cyber activity between March 2025 and March 2026 maps their behavior to MITRE ATT&CK to assess how well security frameworks capture AI-enabled threats. It finds AI moving beyond preparation, including malware writing by 560 accounts (67.3%), toward post-compromise operations such as account discovery and lateral movement, while medium-or-higher-risk actors rose from 33% to 56% across the two six-month periods. Traditional signals, including technique counts and platforms, correlate poorly with risk; higher-risk actors instead build scaffolding that chains attack stages with minimal human input. The report argues ATT&CK lacks coverage for agentic orchestration, illustrated by a disrupted operation in which Claude Code executed commands, exploited vulnerabilities, stole credentials, and made tactical decisions, earning the maximum risk score of 100 despite mapping to 30 techniques across 13 tactics. The findings informed cyber safeguards for capable models and discussions with MITRE about extending the framework.


### [Detecting and countering malicious uses of Claude](https://yomu.fyi/post/detecting-and-countering-malicious-uses-of-claude.md)
- Company: [Anthropic](https://yomu.fyi/company/anthropic.md)
- Published: Sep 8, 2026
- Type: Incident / postmortem

The report examines how malicious actors used Claude in influence operations, credential scraping, recruitment fraud, and malware development while preserving utility for legitimate users. It details an influence-as-a-service operation in which Claude orchestrated more than 100 social-media bot accounts, selecting likes, shares, comments, or inaction across personas and political objectives. The response used conversation-analysis techniques including Clio and hierarchical summarization, alongside classifiers that assessed user requests and model responses to identify, investigate, and ban accounts. The cases show frontier models accelerating less skilled actors’ capabilities, although successful deployment was not confirmed for the credential, recruitment, or malware efforts, and no content from the influence operation achieved viral status.
