Pika(@pika_labs):Under the hood: Text → transformer prompt conditioning Generation → text-conditioned diffusion transformer in compressed acoustic latent space Output → semantic-acoustic autoencoder decodes a 44.1 kHz stereo waveform Flow matching, teacher–student distillation, and post-training with human feedback reduce the generation path to a few high-quality steps.
