A Heart Means Recursion: Exploring Visual Meaning and Communication in VLMs

The findings reveal that VLMs might be capable of rich, creative, and visually-grounded communication, but their interpretation and production of visual meaning diverges from human conventions in surprising ways, and highlights both the promise and challenges of visual communication between humans and VLMs.

Generalization Dynamics of LM Pre-training

This suite provides a new efficient lens on generalization: select intermediate pre-training checkpoints that strongly generalize reasoning and alignment, better than the final pre- or mid-training checkpoints, and select pre-training data that controls and stabilizes generalization dynamics.
