GPTModel to HybridModel Migration

Answer-First Migration Guidance

• The canonical source is docs/user-guide/hybrid-model-migration.md.
• Read the canonical document completely before answering, planning, reviewing, editing, converting, or training.
• Keep migration behavior, commands, mappings, prerequisites, limitations, and validation in the canonical document only. Do not duplicate them in this skill.

Workflow

1. Pull the task artifact first: checkpoint metadata, model provider or config, training command, conversion log, diff, or failure output.
2. Read the canonical migration document completely.
3. Follow only the relevant document sections. Do not invent an unsupported migration path or silently change the target architecture.
4. Validate the result proportionately, invoking the relevant repository build and testing skills when applicable.
5. Report the outcome and link the canonical document for human readers.

Documentation Drift

If the implementation and migration guide disagree:

1. Report the discrepancy before continuing.
2. If the task authorizes a correction, update the canonical document first.
3. Do not add a competing migration rule to this skill.
