Scale AI says its Meta Model API is now in public preview starting at $1.25 per million input tokens, according to CEO Alexandr Wang's post on X. Wang's thread also pointed readers to a Meta research blog post about Muse Spark. The public sourcing visible here is still thin, so the clearest read is the company's own claim and the limited public reaction around it on X, not an independently verified picture of adoption, pricing, availability, partners, or performance.
