AI spends way too much energy staring at pictures; it actually figures out what it's looking at almost instantly, and the rest is just wasted effort.

Do Vision Language Models Need to Process Image Tokens?

The Takeaway
The study shows that image representations become interchangeable very early in the network, unlike text which evolves through every layer. This could lead to a massive reduction in the cost of AI vision by allowing us to 'short-circuit' most of the deep layers.
From the abstract
Vision Language Models (VLMs) have achieved remarkable success by integrating visual encoders with large language models (LLMs). While VLMs process dense image tokens across deep transformer stacks (incurring substantial computational overhead), it remains fundamentally unclear whether sustained image-token processing is necessary for their performance or visual representations meaningfully evolve from early to later layers. In this work, we systematically investigate the functional role of imag
