Vela Modality
Vela Modality identifies whether a request needs text output (AR), image generation (DIFFUSION), or both (BOTH).
307M parameters · Input capacity: 32,768 tokens, including special tokens.
Evaluation
Macro F1 (×100) on the same development sets, compared with the original mmBERT32K Modality model. Higher is better.
Short inputs cover six languages. Long-context evaluation uses six English/Chinese examples placed at three positions and repeated across lengths. Both models process complete inputs in FP32. These development sets informed Vela selection; they are not an independent test set.
