Per-Second Pricing Explained > Pika H3 Flex, an open-weight video model built on MiniMax H3, starts at $0.01 per second, renders 15-second clips in about 7 seconds and exports 4K. Edited by Luis Chavez-Mattos, Director, Product · Published 2026-11-07 · Updated 2026-11-10 ## How much does Pika H3 Flex cost? Pika H3 Flex starts at one cent ($0.01) per second of generated video through the API. A 15-second clip works out to about 15 cents at that floor, and a full minute costs about 60 cents. The model is open weight and built on MiniMax H3, so you can also run it on your own hardware if you have a high-end graphics card. The coverage I've seen listed some of the API prices, and the starting rate is the figure used here. The full price table was shown on screen but not spelled out. ## TL;DR - Pika H3 Flex pricing **starts at $0.01 per second**, which makes a 60-second video about 60 cents. - It can generate a **15-second clip with a soundtrack in as little as 7 seconds**, which is faster than real time. - Output goes **up to 4K** and includes **exportable audio stems** for editing outside the model. - It debuted as the **top open-weight model on Design Arena's text-to-video board**. - It is built on **MiniMax H3** and accepts multiple reference images plus an audio file as inputs. - A **local run is possible** with a high-end GPU, though exact hardware requirements were not given in the material I reviewed. ## What is Pika H3 Flex? Pika H3 Flex is a text-to-video model from Pika, trained on top of MiniMax H3. It is pitched at professional iteration: quick drafts, easy revisions, and outputs you can pull into an editor. It launched as the number one open-weight model on Design Arena's text-to-video leaderboard. MiniMax H3 has become a popular base. Pruna AI, for example, turned the same video model into an open image generation and editing model called PH3 Image. Pika H3 Flex takes the video route and aims to be faster and better than the original. ## What do you get at one cent per second? The headline numbers cover speed, resolution and audio. | Feature | What was stated | |---|---| | Starting price | $0.01 per second | | 60-second video | About $0.60 at the starting rate | | Speed | 15-second clip with soundtrack in as little as 7 seconds | | Resolution | Up to 4K | | Audio | Exportable audio stems | | Base model | MiniMax H3 | | Weights | Open | | Ranking | #1 open-weight model on Design Arena text-to-video board | "Starts at" matters here. Higher resolutions or other settings may cost more, so check the current API rate card before you budget a project. At the floor rate, the arithmetic is simple: | Clip length | Cost at $0.01/sec | |---|---| | 5 seconds | $0.05 | | 15 seconds | $0.15 | | 60 seconds | $0.60 | | 10 minutes | $6.00 | ## How fast is it? Pika describes the generation as faster than real time. A 15-second clip with a soundtrack can finish in as little as 7 seconds, roughly twice as fast as playback. "As little as" means best case, and your results will vary with resolution, settings and hardware. Speed changes how you work. If a draft takes seconds, you can try ten variations of a prompt instead of agonizing over one. The same speed also makes continuous generation practical. The creator who demoed the model pointed to a Twitch-style stream that keeps producing video as an example. ## What are audio stems and why do they matter? Many video models give you a finished clip with sound baked in. If the music is wrong, you regenerate everything. Exportable audio stems let you pull the audio apart and treat it as separate material in your editor. That fits the "professional iteration" pitch. You can keep the picture, swap or remix the sound, and avoid paying for another full generation. ## Can you control the output? The demos showed several kinds of control: - **Camera movement.** Zooms and pans were prominent in the examples, including a clip of two players, one of them a frog, playing ping-pong in a pool. - **Multiple reference assets.** One demo combined five images and a WAV file (a thunderstorm recording) into a single video. - **Targeted edits.** You can drop in images, textures or patterns and change one part of an existing video without redoing the whole clip. Treat these as demonstrations by a reviewer, not guarantees. Your own prompts and assets will behave differently. ## Can you run Pika H3 Flex locally? Yes, with caveats. The weights are open, and the reviewer said they had been running the model locally and expected it to work on a high-end graphics card. The material I reviewed gives no VRAM figure, parameter count or quantization options for Flex. One reference point: in a comparison of derived models, the original MiniMax H3 weights were listed at 143 GB. Pruna's PH3 Image is a different, smaller model, listed at 55 GB in BF16 and 30 GB at int8. Do not assume Flex matches either number. Check the model page for file sizes before you download anything. Local use trades per-second billing for hardware cost. If you generate a lot of video, owning the GPU may pay off. If you generate occasionally, 60 cents a minute is hard to beat. ## Is Pika H3 Flex worth it? It depends on what you need. - **API route:** A starting rate of one cent per second is low for video generation. It suits prototyping, social clips and iteration-heavy workflows where you throw away most drafts. - **Local route:** Open weights give you privacy, no per-second bill and the option to fine-tune or build tooling around it, if your GPU can handle it. - **Caution:** The ranking and speed claims come from the launch announcement and one reviewer's hands-on use. Run your own prompts, at your target resolution, before committing a pipeline to it. ## Frequently Asked Questions ### How much does a one-minute video cost with Pika H3 Flex? At the starting rate of $0.01 per second, a 60-second video costs about 60 cents. Higher-tier settings may cost more, so confirm against the current API pricing. ### How long does it take to generate a clip? Pika says a 15-second clip with a soundtrack can be ready in as little as 7 seconds. That is the best case, so expect variation with resolution and hardware. ### Does Pika H3 Flex output 4K? Yes, resolutions go up to 4K. It also supports exportable audio stems, so you can edit sound separately from the picture. ### Is Pika H3 Flex open source? It is open weight, meaning the model weights are available to download. It is built on MiniMax H3. Check the license on the model page for commercial-use terms. ### Where does it rank? It debuted as the number one open-weight model on Design Arena's text-to-video board. That ranking is specific to open-weight models and to that leaderboard at launch, so it may change.
