Overmind benchmarks show task-specific SLMs beat frontier models, 7x on contract clause quoting

Overmind argues bigger isn't better: small language models trained on specific tasks and real data outperform frontier models on accuracy, hallucination and cost for workflows that must be exactly right.
Three head-to-head benchmarks:
- Legal: 4,000+ questions across 100+ contracts, checking clause presence and verbatim quoting — specialist models were 7x better at exact clause quoting;
- Biomedical: identifying scientific relationships in published papers;
- Aviation safety: turning NASA incident reports into analyst-style synopses.
A Fortune 50 bank's Head of Innovation says they are moving away from very large models toward small models that do one thing extremely well. Technical blog and GitHub repo are available.
