MMBench-Live: A Continuously Evolving Benchmark for Multimodal Models

arXiv:2607.01813v1 Announce Type: cross Abstract: Evaluation benchmarks are essential for assessing vision-language models (VLMs), but most multimodal benchmarks are static, making them vulnerable to temporal staleness, data contamination, and costly maintenance. We present MMBench-Live, a continuously evolving multimodal benchmark built by a multi-agent-driven automated pipeline. Our framework treats benchmark evolution as task-guided dataset construction, integrating structured benchmark specification, feedback-controlled real-time data acquisition, and verifiable QA generation with executab

Why this matters
Why now

The proliferation of advanced multimodal models necessitates more dynamic and robust evaluation methods to counter rapid model evolution and data contamination.

Why it’s important

Reliable and continuously evolving benchmarks are critical for accurately assessing the progress and true capabilities of AI models, preventing misleading performance metrics and guiding research direction.

What changes

The standard approach to evaluating multimodal AI, moving from static datasets to dynamically updated and verifiable benchmarks, will now be more rigorous and less susceptible to gaming.
