ElevenLabs v4 Turbo after Oct 12: $0.04 vs Sume TTS $0.0475

ElevenLabs lists v4 Turbo at $0.011 per 1,000 characters with '72% off until Oct 12'. The struck-through price beside it is $0.04. Sume TTS 1.0 costs $0.0475 per 1,000 characters. For a 37,500-character script, that is $0.41 at the promo, $1.50 at the struck-through price and $1.78 on Sume.

37,500 characters at three prices

The pricing page does not say what v4 Turbo costs after Oct 12. The only post-promo number visible is the struck-through $0.04, which I treat as the likely regular price but not as a confirmed future price. Re-read the page on Oct 13.

Limits that change the plan

Sume TTS caps one request at 20,000 characters, which is $0.95 at the catalog rate. A 37,500-character script needs two requests: for example 20,000 plus 17,500. Cost is linear in characters, so splitting does not change the total of $1.78 (37.5 x $0.0475 = $1.78125).

Sume's gap to the struck-through price is $0.0075 per 1,000 characters, or 18.75%. The gap to the promo price is $0.0365, about 4.3x.

What to do before Oct 12

If you have a large backlog and need ElevenLabs voices, the promo window is the cheap moment and Sume cannot match it. If you want the audio created through the same job API as your video and images, Sume's rate is predictable and has no expiry date written on it. Check the live per-model list at GET /v1/tts-router/models, which the catalog entry for the TTS Router points to.
