The Future is Fine-Tuned: Deploying Task-specific LLMs
summary
Claim: smaller task-specific LLMs are cheaper and production-ready. Workflow uses Ludwig for declarative fine-tuning and Lorax for dynamic adapter serving with LoRA adapters. On a 1,500-row complaints dataset a Llama 27B fine-tune trains in about 1.5 hours on four T4s and yields far better structured JSON outputs than out-of-the-box open models (33% coverage) and beats GPT‑4’s 66% baseline for this task. Lorax serves ~128 fine-tuned adapters atop one base model, cutting GPU footprint and cost while keeping latency negligible.
