Meta's Muse Image Is Two Stories: An Agentic Image Model, and Your Instagram Opted In by Default

Meta Just Became the Fourth Frontier API — and It's Competing on Price, Not the Leaderboard
The Meta Model API opened to developers on July 9 with Muse Spark 1.1: OpenAI-compatible, a self-managing 1M-token context, and prices that undercut the incumbents. Meta's own eval report is honest that it still trails on the hardest coding. Here's how a founder should actually route around that.
