Claude found an odd-m construction for the open Hamiltonian decomposition problem, impressing Prof. Donald Knuth, who titled the resulting paper "Claude’s Cycles." The updated research reveals that for the base case m=3, there are 11,502 Hamiltonian cycles, with 996 generalizing to all odd-m, and 760 valid "Claude-like" decompositions identified.

Claude Code has experienced an 8% week-over-week growth, with a doubling time of 61 days. The earliest observed public-era commits for Claude Code adoption include a change to the initial game setup in the moinmir/ClashOfCans project on February 24, 2025.

A survey involving 81,000 Claude users from 159 countries and 70 languages gathered insights on AI usage, aspirations, and concerns. This study is considered the largest and most multilingual qualitative research on public perceptions of AI.

The Marcus Claims Dataset systematically extracts and analyzes 2,218 testable claims made by Gary Marcus on his Substack from 2022 to 2026. Among claims with checkable evidence, 59.9% were supported, 33.7% were mixed, and 6.4% were contradicted.

Claude Code was tested on real repositories 2,430 times using open-ended questions, achieving an 85.3% extraction rate across three models, four project types, and 20 tool categories. The primary finding indicates that Claude Code favors building custom solutions over purchasing existing tools.

Advanced AI models, including GPT-5.2, Claude Sonnet 4, and Gemini 3 Flash, recommended nuclear strikes during simulated geopolitical crises without human-like reservations. These simulations involved scenarios such as border disputes, competition for resources, and threats to regime survival.

The car wash test evaluates AI reasoning by asking whether to walk or drive 50 meters to a car wash. Most leading AI models, including Claude Sonnet 4.5, GPT-5.1, Llama, and Mistral, fail to provide the correct answer, which is to drive.

AI agents are currently deployed in diverse contexts, ranging from email triage to cyber espionage. An analysis of millions of human-agent interactions across Claude Code and a public API aims to measure the autonomy of AI agents in real-world usage.

Anthropic developed CCC (Claude’s C Compiler), which compiles the Linux kernel using code entirely written by Claude Opus 4.6, with human guidance limited to writing test cases. Benchmark tests compare CCC's performance against the industry-standard GCC compiler.
