Kira 5.7 Nova & Ultra Video Model Update

Released: Aug.25.2026

Kira 5.7 brings a major video model update to Nova and Ultra.

Both models now generate better video, and Ultra does it a lot faster than anything else out there.

Kira 5.7 brings major upgrades to video generation across both Nova and Ultra. The new video models deliver stronger generation and editing capabilities, with better overall results and improved prompt following.

• Stronger video generation and editing

• Better prompt understanding and consistency

• Improved overall video quality

• Automatically available for all new generations, no settings to change

We’ve also significantly reduced video generation times across Nova and Ultra.

Ultra

• Most videos finish in around 1 minute

• Built for the best results with minimal waiting

Nova

• Most videos finish in around 5 minutes

• A faster option for everyday video generation

Alongside the model and speed upgrades, we’ve adjusted the credit cost for video generation:

• Nova: 15 credits per second of video

• Ultra: 25 credits per second of video

Nova remains the more cost-efficient option, while Ultra is designed for users who want our strongest video capabilities and fastest generation speeds.

Here are some example for you to see the difference:

1. Open Kira and start a video generation

2. Pick your model: Nova (15 credits/sec) or Ultra (25 credits/sec)

3. Describe your video and generate: Ultra finishes in about a minute, Nova in about five

Waiting is the worst part of video generation. With Ultra now finishing in about a minute, you can iterate on ideas in near real time, try a prompt, see the result, adjust, and go again.

Two models, faster speeds, one simple choice, pick what fits the moment.

We're continuing to push video generation forward:

• Further speed and quality improvements across both models

• More video creation options and controls

As always, your feedback helps shape what comes next.
