Pika made its AI video generator 60% faster without changing the model weights or reducing the number of denoising steps. The improvement came entirely from inference engineering. And the technical breakdown is worth reading. The project is Pika H3 Flex, a six-step audio-video generator built on MiniMax H3. Pika had already used distribution matching distillation to reduce generation from 50 denoising steps to six. But even with only six steps, there was substantial overhead left in the execution pipeline. So the team went after the GPU bottlenecks. → Cached timestep-dependent AdaLN comp
