Pika H3 Flex
Iteration, without the wait.
Pika H3 Flex is a post-trained H3 model designed to give professional creators the speed to explore and the control to be precise. It keeps the quality you need while generating faster than real-time in almost every configuration.
Resolutions reach 4K, references reach twelve inputs, and editing happens through a reference plus a prompt. Exportable audio stems let you isolate and refine any layer of the soundscape.

A 15 second clip in as little as 7 seconds. Creation at the speed of thought, so the next idea is always one take away.
*Best-case performance.Built for tinkering
Like a pro.
Fast drafts are only useful when they can become final shots. Flex keeps the take, the audio and every reference intact from the first pass to the finish.
768p draft4K finishBuild from multiple references
Combine sketch, image, sound, video and moodboards in one request. Up to twelve inputs hold the look together.
Add, remove or swap anything
Start with a clip and edit with a reference or a prompt. Change a character, camera move, voice or look without rebuilding the shot.
Separate audio stems
Every layer,
on its own track.
Export up to three audio stems to isolate and refine any facet of a clip's soundscape: dialogue, music and effects.

Open weights
Built in the open.
Pika H3 Flex is released with open weights and an inference implementation. Local inference will not necessarily match the optimised hosted API, but the model is yours to inspect, run and build on.

FAQ
Good questions.
Everything else lives in the specs above. For billing, see the pricing page or your account settings.
01What is Pika H3 Flex?+
Pika H3 Flex is a post-trained H3 video model built for professional iteration. Text, image, reference and edit workflows share one model, so a draft can become a finished shot without changing tools.
02How fast is Pika H3 Flex?+
In its fastest configuration it can generate a 15 second clip in as little as 7 seconds. Across matched text, image and reference comparisons it averages 1.8x faster than H3Max.
03Does “seven seconds” mean my request always finishes in seven seconds?+
No. Seven seconds is the best-case generation time for a 15 second clip. Queue depth, resolution, references and finishing mode all affect end-to-end latency.
04What can I use as a reference?+
Up to 12 assets in total: images, video clips, audio, sketches, moodboards or a written prompt. At least one image or video is required in reference mode.
05Can I change part of a clip without starting over?+
Yes. Start from an existing video and add a reference or prompt to adjust a character, camera move, look or voice while keeping the rest of the take.
06Does Pika H3 Flex generate in 4K?+
Yes. The request generates at 768p and upscales once inside the same job to 1080p, 2K or 4K, preserving the generated image content and audio.
07How do separate audio stems work?+
When requested, every generation endpoint can return the video plus up to three WAV files for dialogue, music and effects.
08What is included in the open weights release?+
The model weights and an inference implementation are published together. Local inference speed depends on your hardware and optimisation choices.
09Where can I try Pika H3 Flex?+
Use any Try Pika button on this page. You will be asked to sign in with Google, choose a paid plan and then enter the Studio queue.
