API pricing vs subscription: what my month of Codex would cost on the API

I priced 30 days of my real Codex usage at API rates. A $100 plan covered $745 of API-equivalent work. Here's the math, the script to run on your own logs, and when the API still wins.

Red Flags to Watch for When Choosing Between AI Pentesting Vendors

Choosing between AI pentesting vendors requires looking past marketing labels like 'autonomous' or 'agentic' because the underlying systems vary widely. A Stanford-led study ran different AI agent frameworks against a live 8,000-host network and found that between 55% and 82% of reported findings were confirmed as real vulnerabilities. Swapping only the underlying model moved one framework's valid finding rate from 57% to 80%, yet that same framework still scored lowest overall since its findings stayed shallow. On a CTF-style benchmark two frameworks scored near-identically (48.6% vs 45.9%), but on the live network one scored nearly three times higher on severity and complexity. Buyers should demand proof of exploitation, real-network results, clear safety controls, data handling answers and clarity on what 'continuous' actually means.

Isn't It Time for AVIF Everywhere?

Hosting providers, platforms, and phone makers should adopt AVIF and AV2 more widely, the author argues. Hetzner raised prices multiple times in 2026 citing rising hardware costs, partly driven by AI demand. AVIF generally compresses better than WebP at comparable quality, and the author has switched to AVIF everywhere it's supported, falling back to WebP otherwise. YouTube is preparing to move from AV1 to AV2 as early as 2027. The author also wants better native support for Apple's HEIC format alongside AVIF, and suggests users encode AVIF locally before uploading to ease server load.

Locating the source of a mysterious beep with Claude

Simon Willison used Claude Code to build Beep Locator, a system that triangulates the source of an intermittent beeping sound using multiple devices as listeners. The Python web server coordinates phones, iPads and laptops over WebSockets, using Fast Fourier Transform beep detection and a chirp to align recorded clips, and Willison names the 2007 BeepBeep acoustic ranging paper as the research Claude found. The tool located the beep to within about 40cm, which turned out to be an ancient carbon monoxide detector that wanted its batteries replaced. He started with Claude Code Cloud running Opus 5.5 on his iPhone, then continued on his laptop after Fable 5.2 was released, iterating live by pushing new JavaScript to listening devices so they did not need to be manually restarted.
