Verified custom model fine-tuning providers

This directory surfaces custom LLM fine-tuning providers whose delivery has been verified through shipped work, domain-specific fine-tunes, LoRA/QLoRA adapters, and distillation runs backed by records rather than marketing claims. Each entry reflects evidence reviewed against Trustgent's plan-blind criteria, so paying for a higher tier cannot move a listing up the page. Use it when you're sourcing model fine-tuning services with documented outcomes, LoRA fine-tuning providers, full-parameter training shops, and distillation teams that have shipped training pipelines, evaluation harnesses, and deployed checkpoints for real workloads. Ranked on earned verification level, then record count, then recency. Plan tier is never a ranking input.
