Anthropic brings Claude Fable 5 to the public — with guardrails doing much of the work

Anthropic has announced Claude Fable 5 as a public-facing version of its Mythos-class model, paired with a safety design that routes some higher-risk requests elsewhere. The release matters not just because of the model claims, but because it shows where frontier AI deployment is heading: broader access, narrower permissions, and far more explicit controls.

Project Mythos: When AI Started Finding the Bugs Nobody Else Could

In April 2026, Mozilla shipped fixes for 423 security bugs in Firefox. The month before, it was 76. The month before that, 61. Across all of 2025, the average sat between 17 and 31 a month. So something happened — and Mozilla isn't being coy about it. The "something" was a restricted-access Anthropic model called Claude Mythos Preview, paired with an agentic harness Mozilla's engineers built to put it to work.

OpenAI's Realtime reset and what it means for the rest of the stack

OpenAI just put GPT-5-class reasoning inside the audio loop, took the Realtime API to GA, and priced translation at a third of a cent per minute. The voice agent stack everyone built last year suddenly looks expensive.

After the Hype

My generation, people in their 50s, is the only one who sets up printers for our parents and our kids. Not because we are good with printers — because we have had to learn this industry from scratch more times than is reasonable. Eight-bit machines, PCs, the internet, mobile, cloud, and now AI. And, every few years, someone announces that everything is about to change.
