5.3 Multi-Output Joint Generation Results

For joint multimodal generation, we ﬁrst demonstrate high-quality multimodal output joint generation
demo as shown in Fig. 5. For quantitative evaluation, there is no existing evaluation metric since we
are the ﬁrst model that can simultaneously generate across all 4 modalities. Therefore, we propose
the following metric SIM that quantiﬁes the coherence and consistency between the two generated
modalities by cosine similarity of embeddings:

SIM(A, B) = cos (CA(A), CB(B))
