META AI'S APP DOWNLOADS AND DAILY USERS SPIKED AFTER LAUNCH OF ‘VIBES' AI VIDEO FEED

Anthropic launched a web app for Claude Code yesterday. It is now rolling out to Pro and Max users. Anthropic is attempting to evolve Claude Code beyond a command-line interface tool. It hopes developers will spin up AI coding agents in more places now that Claude Code is on the web. Claude Code has grown 10x in users since its broader launch in May. It now accounts for more than $500 million of Anthropic's annual revenue.

BUBBLE, BUBBLE, TOIL, AND TROUBLE

Pro-AI-bubble arguments are remarkably weak, given the amount of bubble talk. The recent series of circular deals done in close succession has raised concerns. If there is a massive financial crisis or bubble pop that affects AI, it will be mostly for mundane economic reasons rather than the technology not making rapid progress. Such a crisis will have, at most, modest effects on timelines.

CAN YOU INFINITELY LEARN WITH ONLINE RL?

Geospot Infinity is a photo-to-GPS model. It retrieves 10 candidate coordinates for each upload and ranks them for the user. Users then pick the closest. The model attempts to learn from interactions via online reinforcement learning. It turned out that over 65% of users would just click the first guess regardless of accuracy, effectively nullifying the model's ability to learn anything.

BERT IS JUST A SINGLE TEXT DIFFUSION STEP

BERT-style models are essentially just text diffusion models trained on one masking rate. Masked language models can be repurposed into full generative engines by interpreting variable-rate masking as a discrete diffusion process. The standard masked language modeling objective can be turned into a step-by-step generation procedure by gradually corrupting text with mask tokens and training the model to iteratively denoise at increasing mask intensities. A fine-tuned RoBERTa can generate coherent-looking text after slightly modifying the training objective, even without architectural changes.

DO AIS THINK DIFFERENTLY IN DIFFERENT LANGUAGES?

Testing ChatGPT, Claude, and DeepSeek across English, Chinese, Arabic, Hindi, French, and Spanish revealed striking consistency in liberal, secular values regardless of language. All models strongly disagreed that sons deserve education priority over daughters, despite many humans worldwide answering yes. AIs seem to share a mostly cohesive, single underlying worldview across languages rather than adapting to local cultural values.

LOLMIL: LIVING OFF THE LAND MODELS AND INFERENCE LIBRARIES

Researchers built malware that uses Windows' built-in AI model to autonomously find and exploit security vulnerabilities without connecting to external servers. The technique only works on systems with NPUs or GPUs since CPU inference would be prohibitively slow, limiting deployment to CoPilot+ PCs and high-end computers until AI hardware becomes standard.

CLAUDE FOR LIFE SCIENCES

Anthropic is pushing into life sciences following OpenAI and Google with connectors to Benchling, PubMed, BioRender, and genomics platforms, alongside dedicated Agent Skills for tasks like single-cell RNA sequencing quality control. The company aims to support the entire research workflow from early discovery through regulatory compliance and commercialization, rather than just individual tasks like code writing or paper summarization.

AGENTIC AI'S OODA LOOP PROBLEM

AI agents embed untrusted actors within themselves in their training, so fixing hallucinations is insufficient because even if an AI accurately interprets its inputs and produces corresponding output, it can be fully corrupt.
