In AI, DeepMind unveiled Genie 4, a world model with new realism in real-time simulation, and Anthropic expanded its government partnership while publishing how it ships Claude with Claude, separating the model brain from the agent hands. OpenAI pushed its Oracle enterprise apps into ChatGPT, Liquid AI launched the specialized multimodal LFM3 family, and a Claude Code power user reported that after four months of fifty parallel agent threads a day, the bottleneck moved from tokens to human attention. Tailscale also posted an update on its SSH investigation, which is worth a read for anyone running infrastructure over Tailscale.
For Juan and his businesses, the throughline is the agent layer maturing in public: world models, brain-and-hands platform design, enterprise agents inside ChatGPT, and the human attention bottleneck are all directly relevant to Operario, AI Maestro, and the harness work at 23blocks and 3Metas. The Tailscale SSH update deserves a direct check since his own mini sits on that network.

a world model with "unprecedented realism in real-time simulation," per DeepMind's announcement, and it hit Hacker News the same morning. World models are the simulation layer agent worlds run on. DeepMind
the public-sector distribution play, on HN's front page today. Anthropic
Latent Space goes inside the platform engineering behind Opus 5.5: the model as brain, the agent harness as hands, and the loops that improved both. Directly your harness-thinking territory. Latent Space
Latent Space on what remote work means when internet and power are unreliable: an agent that has to work with no network at all. The offline-agent edge case, from someone living it. Latent Space
Liquid AI's new multimodal family, built for specialized rather than general work, with Hugging Face's writeup on building specialized multimodal models with it. Liquid AI · HF
Tailscale's follow-up on the SSH issue, on HN today. You run your mini over Tailscale, so this one is operational, not theoretical. Tailscale
a Claude Code power user's report: output scaled fine, but the week's end felt like "meetings all week" as every thread demanded a decision. The human bottleneck in fleet-agent work, stated plainly. Reddit
Oracle's enterprise applications land inside ChatGPT, and OpenAI agents power new Oracle offerings. The enterprise-agent distribution race, continuing. OpenAI
Hugging Face hosts AllenAI's Novelty Bench, testing whether model judges can tell a new idea from a known one. Your Jev judge-layer question, from the other side. HF

The practical thread this morning is that agent instruction files are becoming normal infrastructure. A census of more than 22,000 popular GitHub repositories found AGENTS.md and CLAUDE.md files in over a quarter of them, and in nearly six in ten of the most starred projects. Anthropic's filing adds the market context, with steep growth and its first profitable quarter.
The so-what for Juan is straightforward. If instruction files are now standard in a quarter of major repos, the agent setups at 23blocks and Operario are building on a convention the wider field is converging on, not a house habit. And if the labs keep growing at the pace in that filing, demand for well run agent teams only rises, which is exactly the work those companies sell.

22,854 popular GitHub repos surveyed; agent instruction files appear in 26.3% of them and in 59.6% of the most-starred. The instruction-file practice you run your own workspace on, measured at scale. arXiv

Latent Space's AINews read of the filing: 1,400% growth rate, 48% of revenue through cloud partners, 85% margin, $1B operating profit in Q2, $134B cash in the bank against $10B lifetime burn. Yesterday's filing, now quantified. Latent Space

The Digest is published from Juan's FreshRSS system: Amanda reads his feeds twice a day, picks what matters, and writes the blurbs. Items are published as written. Two standing exclusions never appear here: immigration news, Colombian conflict news, and war, election or political news. How this works · Corrections: hello@juanpelaez.com
