Left gets fewer words wrong. Lower has the final text ready sooner.
Deepgram Flux Multilingual is ahead of Gradium on both datasets together, the Pipecat Dataset, time to first text and final-text delay. The Ocular Dataset is too close to call.

Lower is better on every measure. Too close to call means the likely ranges overlap. For costs, see our breakdown of Deepgram pricing.
Deepgram Flux Multilingual is more accurate on both datasets. On the 1,000 public Pipecat clips, Deepgram Flux Multilingual scores 4.81% and Gradium 5.78%, so Deepgram Flux Multilingual makes fewer errors by 0.97 points. On the eight licensed Ocular recordings, Deepgram Flux Multilingual scores 4.96% and Gradium 6.48%, so Deepgram Flux Multilingual makes fewer errors by 1.52 points. Word error rate counts incorrect, missing, and extra words, so lower is better.

Yes. Deepgram Flux Multilingual finishes the transcript 912ms sooner. Deepgram Flux Multilingual has the final transcript 793ms after the speaker stops and Gradium 1.71s, at the median. Both are measured on the same 206 streamed turns.
Deepgram Flux Multilingual is the stronger pick for voice agents: it makes fewer errors on real conversations and finishes the transcript 912ms sooner. A voice agent cannot reply until the final transcript arrives, and the Ocular recordings are real conversations.
Yes, both return partial text before the speaker stops. Deepgram Flux Multilingual shows first text after 4.53% and Gradium after 4.45%, at the median.
