What does AssemblyAI charge extra for?

AssemblyAI bills speech-to-text separately from the plan fee. 2026-09-20 auto-check: MODEL LINEUP RESTRUCTURED — flagged for human review rather than auto-verified. Our record listed 'Best model $0.37/hr, Nano $0.12/hr'. Neither of those model names appears in current vendor pricing. As of July 2026 the lineup is Universal-2 async at $0.15/hr and Universal-3.5 Pro async at $0.21/hr, with Streaming and Sync API both $0.45/hr and a flat $4.50/hr Voice Agent API. The 'Nano' budget model appears to have been retired. Rates sourced from the vendor's own pages (assemblyai.com/pricing, assemblyai.com/blog/speech-to-text-api-pricing, assemblyai.com/docs/faq/how-does-pricing-work) plus costbench.com. Tier text updated because vendor-primary sourcing is strong, but Verification Status set to Pending Review because this is a lineup change, not a like-for-like price match — a human should confirm Nano's retirement and whether the old $0.37/hr 'Best' model maps to Universal-3.5 Pro. Entry Price Monthly stays $0 (pure usage-based), so the age-based delta threshold did not trigger. NO snapshot rows written: there is no publicly-priced monthly subscription tier to plot.
