AssemblyAI review

Rates are set per model rather than through a single plan. Input charges run $0.05 to $10 and output charges run $0.20 to $50, so the cheapest small models and the largest ones sit at opposite ends of the same range. The site median for entry input price is €0.07 and for output €0.23.

Signups come with credits in the account and no credit card is required, so a short test run can be made without setting up billing first. Once those credits are used, spending follows the per model rates, with input charges running $0.05 to $10 and output charges running $0.20 to $50 across the catalogue.

The gateway exposes an OpenAI-compatible API, so most client libraries and model strings carry across with small edits. One endpoint fronts the catalogue, and the largest context window is 1,048,576. The provider is AssemblyAI, Inc., headquartered in the US.

The largest context window across the catalogue is 1,048,576, which places AssemblyAI at 11 of 72 brands on that measure. That suits long documents and transcripts, though smaller models in the list sit well below the ceiling.

Listed certifications are SOC 2 Type 2, ISO 27001 and PCI DSS, which covers the common enterprise procurement checks for security management and payment handling. Each of those is named for the gateway itself, so reviewers can raise them during vendor assessment rather than relying on general claims.

Support runs on email, chat and help centre. That mix suits self serve debugging through the help centre and community, plus direct email or chat for harder issues. There is no phone line in the list, so teams that depend on voice support should factor that into their choice.

AssemblyAI lists input charges of $0.05 to $10 and output charges of $0.20 to $50, while Salad lists an input price from $0.06. On entry input price AssemblyAI sits at 28 of 71 brands tracked, so it is priced above the cheapest gateways and below the priciest.
