From Production Traffic to Post-Training: Building a Self-Hosted LLM That Covers the Corporate Request Mix
arXiv cs.AI · Published · 3 min read
In 30 seconds
- What happened
- Researchers consolidated 200+ internal applications onto a single self-hosted LLM by training domain-specific experts for instruction following, function-calling, and task distribution, then merging them.
- Why it matters
- Enterprise engineers managing multiple LLM deployments under data-residency constraints who want to reduce GPU fleet fragmentation and serving costs.
- Watch out
- The approach trains separate models per domain then merges them, which may not generalize equally across all three axes or handle novel request patterns outside training distribution.
