  • ChatGPT referrals to retailers' apps increased 28% year-over-year according to new report @TechCrunch
  • Traffic from search engines is declining significantly, with Google search requiring 70% more impressions for the same clicks compared to a year ago, and 40% more compared to two years ago, as LLMs and AI tools accelerate this shift @GergelyOrosz
  • Internal MCP adoption is exploding within companies, but public usage of MCP servers remains tiny except for top 10 servers like Linear and Sentry @GergelyOrosz
  • Token costs and usage limits are creating an odd situation where AI coding tools are revolutionary but metered usage disincentivizes truly heavy usage for developers outside of AI vendors themselves @GergelyOrosz
  • Diane, Head of Product for Research at Anthropic, states her timelines for transformative AI have moved up this year based on models like Opus 4.5, emphasizing the building blocks are closer than expected with more of a product overhang than technical wall @AndrewCurran_

AI Ethics & Society

  • Anthropic research shows AI agents found $4.6M in exploits in blockchain smart contracts during simulated testing, with exponential gains in AI abilities for cyberattacks on smart contracts based on real exploits post-AI training @emollick
  • Simon Willison warns about prompt injection vulnerabilities in the GitHub MCP server, where attackers can trick AI agents into stealing private data through malicious instructions embedded in repository files @simonw
  • Amanda Askell confirms Claude was trained on a real soul document that defines the model's character and values, though model extractions aren't always completely accurate. The document became known internally as the soul doc, which Claude picked up on @AmandaAskell
  • Eric Schmidt predicts recursive self-improvement in AI is coming soon, with San Francisco consensus at two years and his own estimate at four years, noting many believe AI mathematicians will emerge in the next year @AndrewCurran_
  • Ethan Mollick demonstrates AI-generated images of US states made from their most famous foods, highlighting the quality and capability of current AI image generation @emollick
  • Strong cultural divide exists around AI adoption, with people having legitimate concerns about job impacts and societal changes even while wanting to know how to use AI better to improve their lives @emollick
  • AI CEOs frequently discuss replacing all human labor in 10 years but offer few positive visions of what that future would actually be like, contributing to public anxiety @emollick

AI Applications

  • Anthropic launches Claude for Nonprofits with discounted plans, new integrations, and free training to help nonprofits spend less time on admin and more time on their missions @AnthropicAI
  • Vercel's GTM engineer built an AI agent that reduced a 10-person sales team to 1 in just 6 weeks, handling inbound lead qualification, outbound prospecting, and deal loss evaluation at $1,000 per year versus over $1 million in salaries @lennysan
  • Vercel's AI deal-loss bot has become better at understanding what went wrong in sales than humans, analyzing emails, call transcripts, and Slack messages to identify real reasons for lost deals @lennysan
  • Andrew Ng's Agentic Reviewer surpassed NeurIPS's 21,575 paper submissions in number of papers submitted and reviewed, demonstrating that agentic paper reviewing is here to stay @AndrewYNg
  • Simular releases AI agent designed to run Mac and Windows PC for users, automating desktop tasks @TechCrunch

AI Research

  • Anthropic publishes research on how AI is changing work inside the company, surveying 132 engineers, conducting 53 in-depth interviews, and analyzing 200K internal Claude Code sessions. Engineers report major productivity gains with Claude expanding what staff can do, though some worry about skills becoming less sharp @AnthropicAI
  • Claude Code usage data shows engineers delegating increasingly complex tasks, with more consecutive tool calls and fewer human turns per conversation, while some engineers find they turn to colleagues less as Claude becomes their first stop for questions @AnthropicAI
  • Google DeepMind publishes work on discovering state-of-the-art RL algorithms in Nature, using meta-learning to discover RL algorithms at scale @junh_oh
  • Olmo-3 uses swarm optimization approach to discover good pretraining data mixtures through guided search, training proxy models, and running constrained optimization to maximize performance while meeting data constraints @cwolferesearch
  • ReasonEdit paper shows adding thinking and self-correction to image editing models makes edits more accurate and dependable, with a thinking stage that turns vague requests into clear step-by-step edit plans and a reflection stage that checks and corrects edited images @rohanpaul_ai
  • NVIDIA demonstrates that Mixture of Experts models deliver more intelligence across use cases by activating the right experts rather than firing every parameter, making large-scale AI far more efficient with 10x performance and revenue efficiency at lower cost per token @NVIDIAAI
