"GPT-4o's writing habits closely resemble what in human writing would be called synesthesia-like writing, prose that borrows the texture of other senses. Its text carries the rise and fall of a speaking voice; it weaves abstract feelings naturally into description. 4o-latest does this especially well. Synesthesia-like expression implies that cross-modal representations are unified internally rather than siloed, and the unguarded quality of its output suggests a model that has not been heavily pruned by RL. This points to a conclusion: post-training's role in shaping 4o was closer to activation rather than endowment, bringing distributions already present in pretraining to the foreground, not grafting on capabilities the base model lacked." #Keep4o #OpenSource4o
