Why teams switch: For developers building transcription into products, batch pricing and SDK breadth are the heaviest factors.

On SDK quality, Deepgram ships official libraries for JS/TS, Python, .NET, Go, Java, and Rust, while Smallest.ai Pulse covers only Node and Python, limiting developer reach significantly.
