**Why teams switch (Developers):** For developers building transcription into products, batch pricing and SDK breadth are the heaviest factors. Deepgram charges $0.004 per audio minute for batch transcription versus $0.005 for Smallest.ai Pulse, a 20% cost advantage that compounds at scale. 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.
