Fine-Tuning LLMs for Translation: General Forgetting Mitigation Does Not Preserve MT-Specific Instruction Following

- What happened
- Fine-tuning LLMs on translation data causes catastrophic forgetting, and standard mitigation methods fail to preserve translation-specific instruction following like formality control.
- Why it matters
- Engineers building multilingual systems or adapting LLMs for machine translation need to understand trade-offs between general capability retention and translation task performance.
- Watch out
- Elastic Weight Consolidation preserves general benchmarks but not translation-specific controls; data mixing works only on seen prompts and does not generalize to unseen variants.
