Anthropic's learning platform launched today. Every course, with real lesson counts and durations; the difference between the free badge and the $125 proctored exam you probably cannot sit; and the four hours actually worth taking.

Headless agent runs do not come out of a separate budget — on both Claude and Codex they eat the same meter you type against. The real numbers on limits, overage rates, and why a company seat can carry a fraction of a personal plan's usage capacity.
Biohacking
Training, kitchen and protocol went in one at a time for months. This week they run together: 23 working sets, 225 g of protein, 30 injections a week, and one date in December that reads all of it.
Biohacking
Two kids, 47 and 37 kilos. One eats everything. The other eats exactly seven foods and zero fruit. The plan for both: our own food pyramid, the four routes that get vegetables and fruit into a child who refuses both, 50 recipes, and the cremas and batidos that do the heavy lifting.

The clinical dossier came back. I cannot share the document itself, it is confidential and full of sensitive data, but everything that matters is here: what I asked for, what the physician approved, what got cut, and the one decision I am going to argue with.
Biohacking
Pillar three, in proposal form. Nineteen markers back, and this is what I am asking my clinic for: a 2.5x testosterone blast on a flat daily line, retatrutide doubled, four ways to run the growth-hormone axis, every dose and threshold, and the order going out Monday.

claude agents and /agents are different products solving opposite problems, and the slash command stopped doing what every tutorial says. Five ways Claude Code runs more than one thing at once, what each really costs, and the one cleanup behaviour that will delete someone's work.
Biohacking
A beach day bundles light, movement, immersion and attention into one unusually easy package. Here is what the evidence supports, and what it does not.
Biohacking
One panel flagged my creatinine above range and put my eGFR at 74, which reads as stage 2 kidney disease. The test that settles it came back this morning. Same kidneys, same morning, 47 points apart.

Every new Claude model now embeds an invisible statistical mark in its text output, worldwide. Here is how it works, why code is the worst case for it, and the asymmetry nobody is going to read carefully enough.

The most expensive code your agents write is clean, tested, documented and unnecessary. A working 2026 protocol for finding what to remove, before it hardens into architecture.
Biohacking
2,455 calories, 225 g of protein, seven timed feeds and 25 interchangeable recipes that combine into 5,120 different days. Every gram of it checked by a solver.
