Adaptive multimodal representations and inference optimization target AI cost

MixTok, VisionWeave, and InstantFusion pursue adaptive visual token budgets and interoperable latent interfaces, while PreSTO, speculative-decoding analysis, and latent-space reward modeling attack generation and evaluation costs. The direction is highly practical for serving and model ecosystems, but most gains remain single-study claims requiring independent validation and clearer end-to-end economics.
