Which one is cheaper?

One or both use custom pricing, so it depends on your specific needs.

Different approach here. Luma AI uses hybrid pricing, while AssemblyAI goes with usage-based. That changes the math depending on your team size and usage.

Which one is a better deal?

Depends on what you need. Luma AI: Luma is sitting at the premium end of the AI video space: a $30 entry point with no free tier is a deliberate choice to skip hobbyists and court working creators and studios. That $300 Ultra tier is a bold anchor that makes Pro look like the sensible pick while capturing power users who'd otherwise burn through competitors' credits. AssemblyAI: With no free plan or trial and rates behind a calculator, they're signaling a quality-first API vendor rather than the race-to-the-bottom option, though the low-cent add-on prices keep the entry cost approachable. They're clearly targeting builders embedding speech AI into products who care about accuracy and model breadth over the cheapest per-minute rate.
