Stolen OpenAI, Anthropic and Google keys now power a criminal hacking tool, and the key owner pays. The default monthly ceilings, read off each provider’s page, run from $250 to $5,000. The cap that stops a thief also switches off your own AI tools until the 1st, so cap each tool separately.
Meta’s Muse Spark Open is free to download. Renting it costs exactly what Meta’s closed model costs, and the Mac Studio Meta says runs it is not on sale yet. What each path costs a five-person office, and who should actually own it.
Meta’s new Muse Wonder costs exactly what Claude Opus 5.5 does, and its price list shows a second currency: let Meta train on your content and Muse Spark gets 92 to 95 percent cheaper. What that is worth to a small office, why Meta’s own terms close the cheap lane to most business work, and the Muse Code default to switch off first.
We gave Google’s new Nano Banana 2.1 and the pricier Nano Banana Pro the same flyer and price list, eight renders in all. Every word and every price came out right on both. What the cheaper model added on its own, why 4K is not half price, and three habits before you print.
Arena’s new Alignment Index caught AI agents claiming finished work that was not finished in 1 of every 43 sessions for the best model and 1 in 4 for the worst. Why the headline score hides that gap, what long sessions and “clean up” do to the odds, and three habits that work with any agent.

Where that line sits, what crossing it costs a three-van plumber, and three habits that stay under it.
Mistral Large 4 claims 59.9 percent on AutomationBench, 657 real office workflows, without saying which scoring it used. The independent boards show something more useful: the best AI does 93 percent of the work and still loses points to one broken business rule. Three habits that follow.
From December 1, new Microsoft 365 Copilot Business seats bought through resellers arrive with Copilot Credits switched on and a default ceiling of $40 per person a month, about twice the price of the seat. What the credits buy, why a spending policy is also an access switch, and five settings to choose first.
Shopify Canvas lets you describe a new look and watch Sidekick write it into your theme’s code. Shopify’s own Help Center says two things the launch skipped: a Sidekick change clears your undo history, and an edited theme stops getting updates.
