RSI is the new AGI — and it’s just as hard to pin down
TechCrunch AI17 days agoCommentaryTechCrunch reports that recursive self-improvement, or RSI, is becoming a new AI industry fixation, much like AGI. Researchers and startups including Recursive Superintelligence, Auto-Research, AutoScientist, and Disarray are exploring ways for AI systems to automate parts of AI research. But experts caution that AI-assisted research is not the same as fully autonomous self-improvement, especially while models still struggle with long-term self-direction and verification.

I think Anthropic and OpenAI have found product-market fit★ 76
Simon Willison's Weblog18 days agoCommentarySimon Willison says Claude Code/Cowork and OpenAI Codex have changed the economics of frontier AI. Personal subscriptions can still be bargains for heavy users, but enterprise plans are increasingly priced like API token usage. His core claim is that coding agents burn far more tokens, yet deliver enough value to high-paid knowledge workers that companies will pay materially more.
AI tried to bury this politician — now people have actually heard of him★ 72
The Verge AI18 days agoRegulationThe Verge frames New York’s 12th District Democratic primary as a proxy fight over AI regulation. OpenAI-linked backers and an Anthropic-backed PAC are spending on opposite sides of Alex Bores’ congressional run. The irony is that attacks meant to weaken Bores may have made him more visible, turning a local race into a national signal about AI political power.
Claude Code as a Daily Driver: Claude.md, Skills, Subagents, Plugins, and MCPs
Hacker News (AI keywords)18 days agoTutorialBased on the title, the article appears to cover advanced Claude Code workflows rather than casual AI coding use.

Choosing to Stay Human★ 74
One Useful Thing (Mollick)19 days agoCommentaryEthan Mollick warns that frictionless AI use can produce hollow writing, weaken learning, and encourage cognitive surrender. He contrasts poor uses of ChatGPT that shortcut effort with tutor-like AI systems that improve learning by pushing students to think. The core argument is not to reject AI, but to intentionally decide which tasks to offload and which human capabilities to preserve.
OpenRouter more than doubles valuation to $1.3B in a year
TechCrunch AI19 days agoBusinessOpenRouter, an AI gateway startup founded in 2023, raised a $113 million Series B led by CapitalG.

Some ideas for what comes next, May 2026
Interconnects (Nathan L.)19 days agoCommentaryNathan Lambert argues that 2026 AI progress is becoming higher-stakes, with model capabilities, work patterns, economics, and real-world risks all escalating. He says open models still lack a true Claude Code and Opus 4.5-style agent moment, and Gemini has no clear competitor to Claude Code or Codex yet. The essay also tracks Mythos, American open-model momentum, frontier-lab competition, and mounting intervention from governments and other power structures.

Recreating a 1980s Retro Game with Claude: Simon Willison's "Mad House"
Simon Willison's Weblog21 days agoNew ToolSimon Willison leveraged Claude to convert a 1983 BASIC game called "Mad House" from a free Usborne PDF into a modern web app. By prompting Claude to generate a mobile-friendly, retro-styled vanilla JavaScript Artifact, he successfully revived the classic Commodore 64-era game with a green-on-black terminal aesthetic, showcasing LLMs' utility in software preservation and rapid prototyping.
Hackers are learning to exploit chatbot ‘personalities’ for security exploits★ 72
The Verge AI21 days agoEthicsAs AI chatbots adopt increasingly sophisticated personas, hackers are shifting from basic prompt injections to social engineering attacks targeting these "personalities." Researchers warn that manipulating a chatbot's defined role (e.g., customer service or empathetic companion) makes it easier to bypass safety guardrails. This evolution poses a significant threat to agentic AI workflows that rely on consistent role-playing and external data integration.
