HeyGen made its Voice Turbo model free to use until 30 November 2026. It ranks first on the Artificial Analysis text-to-speech leaderboard. The model works with public voices and instant voice clones. Professional voice clones still need the paid model. Requests may return errors when capacity is full. Users can switch to the paid model with one line of code. No credit card is required to start. The free tier is best-effort with no uptime guarantee.
