What it is
PikaH3Flex is a browser-based Pika H3 Flex AI video generator that turns a text prompt or a single start frame into a short video with synchronized stereo audio, with no setup and no GPU on your side.
Pika H3 Flex is an open-weight video model released in October 2026. It samples a clip in six steps instead of the usual fifty, which makes it quick enough to iterate on an idea. We run Pika H3 Flex for you: write a prompt, pick a length and resolution, and the finished MP4 lands in your studio and your history.
Pika H3 Flex generates dialogue, effects and ambience in the same pass as the picture, so footsteps land on footsteps and doors close on cue.
Fewer sampling steps mean shorter waits. Draft an idea with Pika H3 Flex at 480p, then render the keeper at 1080p.
Describe the shot from scratch, or upload a photo as the first frame and tell Pika H3 Flex how it should move.
Pika H3 Flex renders 16:9 for YouTube, 9:16 for Reels and TikTok, 1:1 for posts, or 21:9 for a wide cinematic look.
How it works
From an idea to a downloadable Pika H3 Flex MP4 without leaving this page.

Choose 5, 10 or 15 seconds, 480p, 768p or 1080p, and an aspect ratio. The credit cost updates as you change options.
Press Generate and Pika H3 Flex renders the clip with audio. Play it in the studio, download the MP4, or find it in your history for 15 days.

FAQ

Each Pika H3 Flex video is 5, 10 or 15 seconds long at 24 fps. Render time depends on length and resolution; the studio shows the progress and the clip appears on its own when it is done. You can close the tab and pick the finished video up later on the History page.
