Anthropic drew two lines around Claude this week — a guided lane for small-business owners and a metered one for the developers running agents hardest. From there: Bun's near-million-line port from Zig to Rust, mostly typed by an AI agent in a week; Wasp's clear-eyed post-mortem on spending five years and five million dollars building a language it didn't need; a chess coach that works by refusing to let the model think; the UK's evaluators capping their own cyber tests so the math still works; the open web pricing out crawlers; multi-token prediction landing in llama.cpp; and what happens when you post a real Monet and call it AI.

• Anthropic draws two lines — Claude for Small Business and the new Agent SDK credit metering
• Bun, ported to Rust by a bot in a week — and a maintainer who won't commit to it
• Wasp: the language was never the moat — $5M and five years of lessons
• The chess coach that isn't allowed to think — Play Magnus on LLM-as-translator
• Autonomous cyber, measured against itself — AISI on a capability curve outrunning its own ruler
• The web pulls up its drawbridge — Google's search index and Cloudflare's defaults
• Multi-token prediction on your laptop — a real gain bundled with a contested one
• The Monet test — when the AI-tell detector fires a false positive
