Keep it — OpenAI has not replaced it

- Labs ship native speech-to-speech models. OpenAI, March 1, 2025 — no announcement link recorded yet.
- How much of the job it covers not the job editorial call
- Parts of it. The job still needs the tool to get finished.

Retell targets the operational reality of call centres — warm transfers, batch outbound campaigns, post-call analysis and compliance recording. A raw realtime model handles the conversation; the business needs everything wrapped around it.
