ANNOUNCEMENT

The following updates for Runway API v1 have been released:
• Upscale to 4K the Gen-4, Gen-4 Turbo, Gen-3 Alpha and Gen-3 Alpha Turbo videos POST gen4/upscale.

The following updates for Runway API v1 have been released:
• Gen-4 Turbo » Create a video using the first image(s) with a text prompt POST gen4turbo/create.

⚠️ 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.

🚀 We’re excited to announce the release of Kling API v1, our latest experimental API for Kling AI.
Kling offers text-to-video, image-to-video, and image manipulation capabilities with multiple model versions 1.5, 1.6 and 2.0
Key features include video generation from elements, special effects, virtual try-on, video extension, lip-syncing, and text-to-speech.
The API supports both free and paid Kling accounts.
As a bonus, you can execute an unlimited number of TTS generations for free via POST tts/create.
This feature is available for all Kling subscription plans, including the free one.

Kling API v1 examples

Runway API v1 maintenance updates:
• Gen-2 endpoints are deprecated since they are no longer available on the Runway website.
• Get image description GET frames/describe response model updated.

⚠️ We suspect that Runway recently started targeting accounts with a large number of image/text-to-video Gen-3 Turbo generations. We're seeing some of these accounts get banned, while accounts with a comparable or greater number of Gen-4 generations are not affected. They probably figured that if you're still running a large number of Gen-3 Turbo generations, you're probably using automation, since humans would naturally switch to the more modern and efficient Gen-4.

We strongly suggest switching to Gen-4 for image/text-to-video going forward.

We updated Midjourney API v2 and setup instructions to support Midjourney Direct Messages channel configuration.
This essentially eliminates the use of the server parameter entirely.
Your current configuration will remain fully functional.
Still, we’re strongly suggesting switching to the Midjourney Direct Messages channel configuration since it greatly reduces Midjourney moderation and the number of CAPTCHA requests.

MiniMax API v1 added support for character reference for the image endpoint POST images/create.

EXAMPLE

We’re excited to announce the release of TemPolor API v1, our latest experimental API for TemPolor, an AI-powered, royalty-free music generation service that creates high-quality soundtracks from text prompts, custom lyrics, MIDI, and supports voice cloning. TemPolor offers extensive customization for instrumental tracks, including chords and BPM. Supports export in mp3, wav, and stems, and it can generate stems from users’ audio files. Up to 10 tracks can be generated concurrently, with unlimited generations available on the Ultra plan.
