Adds Multilingual Keyterm Prompting for Nova-3 Multi — Nova-3 multilingual now supports multilingual keyterm prompting, allowing you to pass up to 500 tokens (~100 words) to boost recognition of brand names, industry jargon, proper nouns, and other mission-critical vocabulary across multilingual audio.

Bad Request: The selected Nova-3 model does not support keyterm prompting. Contact Deepgram support for assistance with updating your model version.Learn more in the keyterm prompting documentation.
