Vision Is Not Overhead: One-Pass Block Drafting for Lossless Speculative Decoding in Vision-Language Models
TL;DR
GLANCE introduces a one-pass block drafting method for vision-language models (VLMs) that accelerates decoding without loss of output quality. It achieves up to 2.93x faster decoding compared to traditional autoregressive methods by efficiently utilizing visual information.
✦ Why It Matters
Implement GLANCE in your VLM projects to enhance decoding speed and efficiency immediately.
Key Takeaways
- Adopt GLANCE for faster decoding in vision-language tasks.
- Utilize the one-pass method to reduce computational overhead.
- Explore the impact of next-token entropy on block length.
- Access the GLANCE code to integrate into your projects.
How It Works
GLANCE employs a block-diffusion head that reads the already-fused vision-language state of the target model. This allows it to fill an entire block in one forward pass, bypassing the need for sequential processing.
By leveraging visual information without additional cost, GLANCE enhances the efficiency of the decoding process.
