1. AI SDK Deepgram Provider Adds Model Support and Fixes Dropped Speech Options

Vercel. The AI SDK shipped @ai-sdk/deepgram@3.1.0, a feature release for the Deepgram speech provider that stops silently dropping transcription options such as keyterm, paragraphs, intents, sentiment, and replace, expands support beyond the nova-3 model, and makes the text-to-speech speed parameter (0.7 to 1.5) actually pass through instead of being ignored. It also adds response metadata like model details, character counts, and request IDs, and improves error parsing so Deepgram’s real messages surface. The release includes a breaking change that removes the automatic diarize=true default, since speaker diarization is a paid add-on, so teams relying on that behavior must set it explicitly. Source
