Specialized runtimes for multimodal models

Multimodal models need different execution, streaming, and scheduling strategies. We tune the runtime around each model's behavior.

Model-specific runtimes

Compilation, scheduling, batching, and memory use optimized for each model.

Streaming-native execution

Input and output streaming designed for interactive multimodal workloads.
