skipped (unsupported modality): 4 — skylark-embedding-vision-251215, skylark-embedding-vision-250615 (embedding), Hyper3d-Rodin-Gen2 (hyper3d), Hitem3d-2.0 (hitem3d)

Note: byteplus family "seed-2-0-code" (upstream) vs backend's "seed-2-0-code-preview" naming is a cosmetic family-label difference only — same id/date (seed-2-0-code-preview-260328) present in both, not counted as new. All other byteplus chat families have their newest upstream date already matching the backend's newest date — no version-bump gaps found there.
