Deepgram
the clearest pricing table here, for a price that assumes your recordings become their training data.
excellent, itemised, honest-looking pricing — with the most important term about it disclosed in an api parameter rather than on the pricing page.
the streaming rate of $0.288 an hour is the lowest real-time figure in this ranking, the pricing table itemises add-ons cleanly, and $200 of free credit makes evaluation easy. on presentation alone deepgram looks like the most transparent vendor here.
then you find the condition. standard rates assume enrolment in deepgram's model improvement partnership programme — your audio helps train their models. you can opt out by passing mip_opt_out=true, and doing so forfeits the roughly 50% discount that enrolment buys. so the real choice is $0.288 an hour with training or about double without, and only the first number appears in the comparison tables everyone publishes.
the description above is ours, condensed from the ranking. pricing moves — check it on the vendor's own page before you rely on it.

we researched this category against vendors' own pricing pages and licence files. that is where this line comes from — not from the vendor, and not from anything they paid for.
