ElevenLabs v4 Turbo promo ends Oct 12: a 120,000-character batch

A 120,000-character batch costs $1.32 on ElevenLabs v4 Turbo at the promotional $0.011 per 1,000 characters, and $4.80 at the regular $0.04 once the offer ends. Sume TTS bills the same text at $0.0475 per 1,000 characters, which is $5.70, as six requests of 20,000 characters at $0.95 each.

ElevenLabs' API pricing page (read 2026-10-09) lists v4 Turbo at $0.011 per 1K characters with "72% off until Oct 12". Sume's price is from its public catalog (read 2026-10-09). The promo is the cheapest of the three by a wide margin; the question is whether you can use it before the date.

The numbers

ElevenLabs promo: 120,000 / 1,000 x $0.011 = $1.32. Regular: 120 x $0.04 = $4.80. The page also lists v2 Multilingual at $0.08 per 1K, which would be 120 x $0.08 = $9.60 for the same text.

Sume: 120 x $0.0475 = $5.70. The catalog caps one request at 20,000 characters, so 120,000 characters is six jobs, and the maximum per job is $0.95: 6 x $0.95 = $5.70. Spaces and punctuation count on Sume, so count the file with the same rule.

What a deadline changes

If the batch is ready now, run it before October 12 and keep the files; the saving against the regular price is $3.48. If scripts are not final, the promo is not a reason to render early, because re-rendering after an edit pays the regular rate. A common compromise is to render only locked scripts under the promo.

Sume does not list an ElevenLabs model, so you cannot buy v4 Turbo through Sume. What Sume offers for a batch like this is one billing and job model for the whole video: poll GET /v1/jobs/:id/status, resend with the same Idempotency-Key after a timeout without a second charge, and then use the audio in a timeline.

If you do use Sume for the voice

Split the script at paragraph ends, not mid-sentence, so each of the six requests is a clean file. Request wav with timestamps.words if you need to cut by sentence later. The join is $0.01 per up to 20 parts with timeline audio, so the six files become one for one cent.

Before you queue the batch

Check three things first. Count characters the way the vendor counts them, since a billing difference of a few percent matters at this size. Confirm the terms for commercial use of the audio. And render one clip from the final script and listen to it, because a promo discount on a take you reject is not a saving.

If the batch goes into video, plan the join too: six files joined into one on Sume is a single timeline audio job at $0.01.
