Where the docs disagree

  • xAI: the markdown pricing page lists one flat rate, the rendered page prices by resolution

    The rendered pricing page at docs.x.ai lists separate 480p, 720p and 1080p rates for each Grok Imagine video model. The markdown version of the same page lists one flat per-second rate per model, equal to the 480p tier.
