Optionalimagebool [L] image-token mask for the bidirectional attention overlay.
Absent when the prompt carries ANY audio — audio(-containing) prompts
run fully causal (02d723a:docs/design/generic-model-support.md §6.6).
OptionalmropeQwen3.5/3.8 vision: the request's mRoPE positions + decode delta, owned by the media prompt input the graph binds.
Optionalmultimodalbool [L] union multimodal soft-token mask (image | audio) for per-layer-input id zeroing. Absent on the legacy vision-only shape, where zeroing falls back to imageMask.
OptionalprefixProducer identity includes all media and preceding rendered tokens.
Prepared embeddings for vision/audio prompts. Qualified models consume this through the media prompt input the graph binds (
bindMediaInput). Token-only prefix caching remains disabled for media.
