Gemma 3 builds spatial maps but doesn't use them for answers, study finds

A recent study on Google's Gemma 3 model has revealed that while it can construct a spatial map from text-based instructions, it does not appear to utilize this map for generating answers. Researchers found that the model's performance on chain questions improved when it was forced to read from this unused spatial map, suggesting a disconnect between its internal representation and its output generation. The study also indicated that Gemma 3 processes spatial information on a per-sentence basis rather than relying on a coherent, integrated map. AI

IMPACT This research highlights potential limitations in how LLMs process and utilize spatial information, suggesting areas for future model development.
