• Meta issue Call to contributions: refactor output tracing in transformers huggingface/transformers#43979 is closed, but GPT-Neo still used old manual output collection on origin/main.

• Attempted Refactor GPT-Neo output tracing to use capture_outputs/can_return_tuple huggingface/transformers#44018 after Refactor GPT-Neo to use @capture_outputs and @can_return_tuple decorators huggingface/transformers#44068, then aborted cleanly due to duplicate conflicts.
• Validation run: python -m py_compile src/transformers/models/gpt_neo/modeling_gpt_neo.py passed.
• LSP diagnostics for src/transformers/models/gpt_neo/modeling_gpt_neo.py reported no issues.
• Pre-existing untracked .fast-agent and jsonl files were left untouched.

Next steps:

• Run the relevant GPT-Neo test suite, e.g. tests/models/gpt_neo/test_modeling_gpt_neo.py.
• Run make style or make fix-repo before any PR submission.
• Have a human maintainer/reviewer inspect the conflict resolution, especially the intentional omission of PR-side cache_position changes to match current main.
