Researchers have developed a novel approach called Factorized Vector Quantization (FVQ) to improve the semantic fidelity of discrete visual tokens in multimodal models. Contrary to the belief that quantization error inherently causes semantic loss, the study found that the effective bit budget of discrete indices is more critical for performance. FVQ, which quantizes complementary views of visual features with parallel codebooks, continues to improve at larger bit budgets, matching continuous visual representations in multimodal understanding. This method achieves state-of-the-art performance among discrete-representation models, outperforming Emu3-Chat and UniAR, and is competitive with continuous-representation models like Qwen3-VL. AI
