Goal

Migrate each remaining model family to the semantic Task SDK introduced in #1226. Each child issue covers one family so contributors can implement and review migrations independently.

This inventory is based on public main and open PRs checked on 2026-09-28: 112 families remain, including 21 covered by open Task migration PRs and 91 not started. Families already using semantic Task bindings are excluded.

Contribution boundary

  • Keep a normal migration within families/<family>/**. Preserve every existing primary and secondary capability, including batch, streaming, raw-output and stateful paths where applicable.
  • Map each capability to an existing semantic Task contract; bind only Tasks implemented by the loaded bundle. Keep model-specific preprocessing, inference, postprocessing, configuration and tests with the family.
  • Preserve existing checkpoint cases, numerical oracles, thresholds, supported profiles, and CLI, example and benchmark behavior. Do not weaken passing criteria to pass CI.
  • Add public C and C++ SDK coverage and report actual build/load/run and reference evidence. State untested configurations honestly. Rebuild bundles when the primary Task changes.
  • If a family exposes a genuinely missing shared contract, open and link a separate prerequisite issue before completing that family. Do not add a shared model implementation or a cross-family dependency.

Coordination

Comment on a Not started child issue before beginning work. One family should have one migration PR linked to its child issue. An open PR already covering a family is marked In progress and is not available to claim. Separate family CLI work is linked for coordination but does not count as Task migration progress.

The child-issue checklist below is the source of truth. Close this epic when every child issue is completed or publicly resolved with an explanation.

Child issues

Native sub-issue groups: #1543 (families A–M, 54 issues) and #1544 (families N–Z, 58 issues). GitHub allows at most 100 direct sub-issues per parent, so the family issues sit one level below these two groups. The checklist also links every family directly for status tracking.
