When Visualizing is the First Step to Reasoning: MIRA, a Benchmark for Visual Chain-of-Thought

Yiyang Zhou, Haoqin Tu, Zijun Wang +11

We propose MIRA, a new benchmark designed to evaluate models in scenarios where generating intermediate visual images is essential for successful reasoning. Unlike traditional CoT…

AHELM: A Holistic Evaluation of Audio-Language Models

Tony Lee, Haoqin Tu, Chi Heem Wong +6

Evaluations of audio-language models (ALMs) -- multimodal models that take interleaved audio and text as input and output text -- are hindered by the lack of standardized benchmark…
