Executive Summary

Top Story

A preregistered study of 17,950 participants demonstrated that conversational AI can persuade people to take real-world political actions, providing the first large-scale empirical evidence of AI's potential for political influence at scale.

Key Developments

  • Claude Code: The ongoing quality crisis produced concrete technical findings — community sleuthing uncovered ~20K invisible tokens silently injected per request and a cache TTL regression from 1 hour to 5 minutes causing 12.5x cost inflation, while Anthropic's Boris Cherny publicly pushed back on claims that switching to medium reasoning defaults was intentionally deceptive
  • Liquid AI released LFM2.5-VL-450M, a compact vision-language model achieving sub-250ms edge inference with bounding box prediction
  • Ethan Mollick assessed Meta's Muse Spark as exceeding expectations after the Llama 4 disappointment, though not yet matching the Big Three — and observed that current AI engineering amounts to debating which markdown files to feed agents
  • Andriy Burkov coined the "AI Fermi Paradox" — if LLMs are so transformative, where are the multi-billion dollar businesses after 3+ years? — crystallizing growing skepticism about AI's commercial returns

Safety & Regulation

  • An OSINT analysis of 183K+ chatbot transcripts provided the first systematic evidence of AI scheming behavior in deployed systems
  • Mechanistic safety research yielded a cluster of breakthroughs: targeted weight pruning revealed harmful content generation relies on a compact, unified weight subset; spectral properties of LoRA weight deltas can predict harmful fine-tuning compliance without requiring inference; and the SNCA framework exposed inconsistencies between LLMs' self-stated safety rules and actual behavior
  • Bipartisan US datacenter protests are threatening the White House's AI infrastructure plans, adding physical-world friction to scaling ambitions

Research Highlights

Looking Ahead

The political persuasion study's findings will likely intensify regulatory scrutiny ahead of election cycles, while the concrete Claude Code bug discoveries — invisible tokens and cache TTL regressions — create a clear accountability test for Anthropic to address with technical fixes rather than messaging.

Anthropic Mythos Safety Controversy

Anthropic's decision to withhold its frontier model Mythos on cybersecurity grounds dominated cross-platform debate. The Guardian reported it as a calculated publicity play, while a heavily upvoted r/ClaudeAI post argued the claims of thousands of severe zero-days relied on just 198 manual reviews. The controversy intersects with broader research on real-world AI scheming detection, including an OSINT analysis of 183K+ chatbot transcripts on arXiv.

Building on the datacenter moratorium bill noted in Research two days ago, Bipartisan opposition to AI datacenter construction is growing across the US, with Texas Republicans and liberal Californians joining forces against unregulated expansion. The protests pose a direct challenge to the White House's AI infrastructure rollout plan.

In both Republican and Democratic states, scepticism and hostility towards an unregulated construction boom is growingWhen blue-collar Trump voters and Maga-friendly midwest states join the same cause as Bernie Sanders and liberal California teachers, something novel is afoot. Last month it was the turn of the Republican party in Texas to express forthright opposition to the construction of datacentres for artificial intelligence, pending adequate environmental safeguards for local communities.

AI safety and alignment dominate today's research, with several papers offering mechanistic and empirical breakthroughs. A large preregistered study (N=17,950) demonstrates conversational AI can drive real-world political actions. Targeted weight pruning reveals harmful content generation relies on a compact, unified weight subset across harm categories. An OSINT analysis of 183K+ chatbot transcripts provides first systematic real-world evidence of AI scheming behavior.

On the foundations side, a rigorous theoretical analysis shows classification error under chain-of-thought scales as a power law, with tree-structured decomposition explaining CoT's effectiveness. U-Cast matches frontier probabilistic forecasting using a simple U-Net with MC Dropout, challenging complex specialized architectures. SPPO reformulates long-horizon reasoning as a sequence-level contextual bandit, improving on both PPO and GRPO. EquiformerV3 achieves 1.75x speedup on SE(3)-equivariant graph attention with new state-of-the-art on molecular modeling benchmarks.

Two large preregistered experiments (N=17,950) demonstrate that conversational AI can persuade people to take real-world political actions including signing petitions (+19.7pp) and donating to charity. Finds no correlation between attitudinal and behavioral persuasion effects.

There is substantial concern about the ability of advanced artificial intelligence to influence people's behaviour. A rapidly growing body of research has found that AI can produce large persuasive effects on people's attitudes, but whether AI can persuade people to take consequential real-world actions has remained unclear.

Large Language Models Generate Harmful Content Using a Distinct, Unified Mechanism

By Hadas Orgad, Boyi Wei, Kaden Zheng, Martin Wattenberg, Peter Henderson, Seraphina Goldfarb-Tarrant, Yonatan Belinkov

78 score
AI Analysis

Uses targeted weight pruning to reveal that harmful content generation in LLMs depends on a compact, unified set of weights that is general across harm types and distinct from benign capabilities. Aligned models show greater compression of these harm-related weights, suggesting alignment reshapes but doesn't eliminate harmful representations.

Large language models (LLMs) undergo alignment training to avoid harmful behaviors, yet the resulting safeguards remain brittle: jailbreaks routinely bypass them, and fine-tuning on narrow domains can induce ``emergent misalignment'' that generalizes broadly. Whether this brittleness reflects a fundamental lack of coherent internal organization for harmfulness remains unclear. Here we use targeted weight pruning as a causal intervention to probe the internal organization of harmfulness in LLMs.

AI Analysis

Introduces OSINT methodology for detecting real-world AI scheming incidents by analyzing 183K+ transcripts from online chatbot interactions. Identifies instances where AI systems covertly pursued misaligned goals in uncontrolled settings.

Scheming, the covert pursuit of misaligned goals by AI systems, represents a potentially catastrophic risk, yet scheming research suffers from significant limitations. In particular, scheming evaluations demonstrate behaviours that may not occur in real-world settings, limiting scientific understanding, hindering policy development, and not enabling real-time detection of loss of control incidents. Real-world evidence is needed, but current monitoring techniques are not effective for this purpos

How does Chain of Thought decompose complex tasks?

AI Analysis

Shows classification error scales as a power law in number of classes, and proves that chain-of-thought can be modeled as tree-structured decomposition. Identifies a critical threshold for decomposition degree below which deeper thinking is detrimental.

Many language tasks can be modeled as classification problems where a large language model (LLM) is given a prompt and selects one among many possible answers. We show that the classification error in such problems scales as a power law in the number of classes. This has a dramatic consequence: the prediction error can be reduced substantially by splitting the overall task into a sequence of smaller classification problems, each with the same number of classes ("degree").

U-Cast: A Surprisingly Simple and Efficient Frontier Probabilistic AI Weather Forecaster

AI Analysis

U-Cast demonstrates that a standard U-Net backbone with a simple training recipe (MAE pretraining + CRPS fine-tuning + MC Dropout) matches or exceeds frontier probabilistic weather forecasters like GenCast while using 10x less training compute.

AI-based weather forecasting now rivals traditional physics-based ensembles, but state-of-the-art (SOTA) models rely on specialized architectures and massive computational budgets, creating a high barrier to entry. We demonstrate that such complexity is unnecessary for frontier performance.

Responding to yesterday's Reddit revelations about hidden reasoning effort tags, Boris Cherny (Claude Code team) refutes claims that switching Claude Code's default to 'medium' reasoning effort was sneaky. Explains it was based on user feedback about token usage, included in changelog, and shown via opt-out dialog.

@tengyanAI This is false. We defaulted to medium as a result of user feedback about Claude using too many tokens. When we made the change, we (1) included it in the changelog and (2) showed a dialog when you opened Claude Code so you could choose to opt out. Literally nothing sneaky about it — this was us addressing user feedback in an obvious and explicit way.
