Objective metrics, no spin.
Replacing first-line phone agents, inbound qualification, appointment booking, healthcare scheduling.
Complex multi-turn sales conversations (still better with humans), pure transcription needs (use Deepgram), regulated workloads requiring specific certifications.

Commercial music for major brand deployments (legal exposure with ongoing lawsuits), or professional music production (real DAWs and musicians fit better).
