Gen-3 Alpha Video to Video gen3/video and Gen-3 Alpha Turbo Video to Video gen3turbo/video updated to support restyled first frame, parameter imageAssetId.

The Riffusion API v1 has been updated to support:
• Downloading the mp3, wav or stems of your song GET music/download
• Support for the trim transformation has been added to POST music/create-compose

• During Runway API v1 maintenance, we removed the optional features response field. It was populated as follows:

"features": {
"storageGB": 500,
"numPlanCredits_permitted": 2250,
"numPlanCredits_used": 1315
}

The credits were not very useful since the values provided were pre-execution values, which caused some confusion among users. Hence, we decided to remove it. Please use GET features instead.
• We updated our Q&A “How to avoid Midjourney bans?” and “How to avoid Runway account suspension?” sections, please take a look.
• Looking for n8n workflow automation support? Please consider the n8n-nodes-useapi package by lvalics.

PixVerse API v2 has been updated to support PixVerse V4, see POST videos/create-v4.
EXAMPLES

PixVerse API v2 has been updated to support PixVerse V4 (part II):
• Create video using first and last frames POST videos/create-frames-v4.
• Extend video POST videos/extend-v4.
• Restyle video POST videos/restyle-v4.
• Lip sync video POST videos/lipsync, updated to use V4.
EXAMPLES

Mureka API v1 has been updated to support the recently released model O1, enable stems download and generate instrumental music.
• Currently supported models: O1, V6 and V5.5.
• Create instrumental music POST music/create-instrumental.
• Download the song license and stems POST music/download.

Runway API v1 has been updated to support Gen-4, see POST gen4/create.

EXAMPLES

• MiniMax API v1 TTS (text-to-speech) has been updated to support the recently added speech-02-hd and speech-02-turbo models. The speech-02-hd model is now the new default for all TTS audio/ endpoints.
• PixVerse API v2 has been updated to support Off-Peak Mode, and a few small fixes have been applied to effects default sound generation.

Midjourney API users:
• When turning on the V7 model, you MUST complete the personalization training on their website. Until that step is completed, you will not be able to use V7. Once you have completed the training, you can go back and turn Personalization off via /settings.
• Another catch: as of now, V7 does not support standard mode, it only supports --turbo or --relax. If you have a standard account where --relax is not supported, all generations will be executed in --turbo mode even though the settings indicate that --fast mode is selected. This is likely to change soon and work as it did with V6.

⚠️ Riffussion API has been decommissioned.
Currently we do not have plans to re-release it and recommend switching to Mureka API for music generation.

👉 PixVerse has updated its internal API for old v3.x routes - you'll get a 404 if you try to call an old 3.x route.
Consider switching to v4.
We will update the v3.x routes tomorrow to match the internal API changes.

PixVerse removed v3x support for effects and lipsync, and we will be dropping v3x support as well.
Here’s the PixVerse API v2 v3x to v4 migration map:
• POST videos/create-v3 → POST videos/create-v4.
• POST videos/create-frames-v3 → POST videos/create-frames-v4.
• POST videos/extend-v3 → POST videos/extend-v4.
