The BriefMeta released Muse Spark 1.1, an AI model built to write and fix code and operate software on its own, and for the first time Meta is charging developers to use it through a paid API instead of giving its AI away for free. It can hold about a million tokens of context at once (roughly a small book's worth of code and instructions) and Meta says it matches or beats the current top models from Anthropic and OpenAI on real coding work. It matters because Meta spent years as the big free, open alternative, so putting its best model behind a paywall is a real strategy shift, and it drops a fourth deep-pocketed player into a fight that already has OpenAI, Anthropic, and SpaceXAI.
Level UpAs AI coding models get better at running on their own, the durable skill is shifting from writing code to designing the loop the agent runs in: what it should attempt, how it checks its own work, and when it should stop. Armin Ronacher, the creator of Flask, argues exactly this in 'The Coming Loop.' Try it this week: take one repetitive task you normally do by hand and sketch it as an agent loop with a clear success check, instead of just prompting once. The Coming Loop (Armin Ronacher)
