## Vendor claims and neutral signals

- Pika says H3 Flex generates video with synchronized stereo audio in six sampling steps and takes up to 12 reference inputs. Vendor description; we did not run it.

## Notes

- Local inference covers native 480p and 768p; 1080p, 2K and 4K, audio stems and prompt enhancement are Pika API features.

## What we tested

Nothing yet. We have not run Pika H3 Flex ourselves, so every fact here is Reported from the sources below.

## Not verified, left out

- Parameter count: the model card does not state one; the released files are adapters on top of MiniMax H3, so we do not report a size.
- Benchmark tables: Pika's own; not reproduced here.
- API pricing for the hosted 1080p, 2K and 4K tiers was not captured.
