New testbed evaluates image tokenizers as visual languages in multimodal models

By PulseAugur Editorial · [1 sources] ·

This research paper introduces a novel autoregressive testbed designed to evaluate image tokenizers within unified multimodal models. The study focuses on how these visual tokens interact with text during joint pretraining, analyzing task-specific validation losses across text, image, text-to-image, and image-to-text prediction tasks. Key findings indicate that losses should be analyzed per task, as they scale differently and rank tokenizers uniquely. The research also demonstrates that while image tokenizer choice impacts text modeling, image-to-text loss offers a more consistent signal for downstream performance than text-to-image loss. AI

IMPACT Introduces a new evaluation framework for understanding the role of image tokenizers in multimodal AI systems.

    Studying Image Tokenizers as Visual Languages in Unified Multimodal Models

    Image tokenizers define the ``visual language'' of unified multimodal models, yet are commonly studied through isolated metrics or generation-/understanding-only evaluations. These evaluations do not fully capture how visual tokens behave when modeled jointly with text. We build …
