What the models said for it

Verbatim evidence the judge attached to positive labels.

“Choose Deepgram if you're optimizing speech recognition inside your own stack.” GPT-5.4 mini · AI voice agents · comparative prompt · alternative

“Optimize: Use Deepgram for transcription” Grok 4.1 Fast · AI voice agents · budget prompt · alternative

“it's a very strong mid-market option” GPT-5.4 mini · AI voice agents · direct prompt · alternative

And against it

Verbatim evidence attached to negative labels. A warning on a product with few labels is a warning; on a product with many, it is one voice among them.

How it is countedHide how it is counted

Every page deepgram.com exposes, subdomains included. Kind is read from the address and title. The last 90 days, the latest date and the twelve months count pages by when they were published, from the site's feeds, a date in the address, or the page's own publication date, read from up to a hundred of its most recently changed pages; a page that says only when it last changed is counted in its kind but not in when, so the recent counts are a floor, and a kind none of whose pages gives a publication date reads undated. An event counts as online when its address or title says so (webinar, on demand, virtual or online summit); a conference, summit, trade show, expo or roadshow that does not say so is counted as a conference or event, which on a vendor's site is mostly in person. Read October 5, 2026.
