Meta finally sells you an API - and it speaks OpenAI's language out of the box
Meta released Muse Spark 1.1, an agentic multimodal model with a million-token context window, and for the first time opened the Meta Model API so developers can actually buy access to it. It's a public preview, US developers first. Replit, Cline and Box were early partners. Tech press reports the API at $1.25 per million input tokens and $4.25 output, undercutting most of the frontier tier. The detail that matters is buried in Replit's quote: it ships in 'a clean OpenAI-compatible package' — and press coverage says the endpoint also speaks Anthropic's Messages format.
What it actually means
The interesting thing isn't Meta's benchmark chart. It's that switching now costs you a config change instead of a rewrite. Two weeks ago the story was American firms quietly moving to cheaper Chinese models; this is the same thread arriving at its conclusion — the model layer is becoming a commodity you swap, not a platform you marry. If your code still hard-codes one vendor's SDK, that's now a liability, not a shortcut. Don't move production onto a public preview from a lab with no API track record.
