Audio and video API dates to calendar: Oct 12, Nov 11, end of 2026

Three dates from vendor pages affect an audio and video pipeline this fall: ElevenLabs v4's discounted API price ends Oct 12, Seedance 1.5 Pro retires Nov 11, and Gemini 3.8 Flash TTS audio output is priced at $9.00 per million tokens through the end of 2026. One more already passed: Sora 2 and Sora 2 Pro were discontinued on Sept 24, per the ElevenLabs changelog.

Put them in a calendar, then check which of your jobs and budgets cross each date.

The dated list

All entries are as listed on the vendor pages read on 2026-10-03.

What the Oct 12 date implies

The price page gives $0.022 per 1K characters for v4 with a 72% discount. The implied undiscounted rate is $0.022 divided by 0.28, about $0.079 per 1K characters. That is arithmetic on the page's two numbers, not a listed price, so confirm the post-Oct 12 figure on the page before you budget it. v4 Turbo is listed at $0.011 per 1K, with no discount noted in the entry.

On the Sume side, check your own rate card rather than carrying a vendor price across: Sume bills video at provider list times 1.25 per its video docs, and publishes its own audio job prices.

A countdown script

This prints the days left to each date from today. Edit the list as vendors move their dates.

from datetime import date

DATES = [
    (date(2026, 10, 12), "ElevenLabs v4 discount ends"),
    (date(2026, 11, 11), "Seedance 1.5 Pro retires"),
    (date(2026, 12, 31), "Gemini 3.8 Flash TTS price window ends"),
]

today = date.today()
for when, what in DATES:
    days = (when - today).days
    state = "passed" if days < 0 else f"{days} days left"
    print(f"{when.isoformat()}  {state:>14}  {what}")

What to check against each date

A date only matters if something of yours crosses it.

• Before Oct 12: list long-running TTS batches and decide whether to run them while the discounted rate applies.
• Before Nov 11: search your code and stored prompts for Seedance 1.5 Pro ids, and read the live model list instead of hard-coding one. The Sume catalog is at GET /v1/videos/models.
• Before year end: convert the Gemini token price to a per-minute figure with your own measured tokens per second of audio, because the pricing entry gives tokens, not minutes.
• After Sept 24: any workflow that still names a Sora model needs a replacement. Route through a catalog id or sume/auto so a retirement does not break the run.
