Open-Switch answers one question: can an open model replace your closed LLM API on YOUR data?
It runs your workflow through open-weight models, scores them with bootstrap 95% CIs, and gives a verdict: Safe Switch or No Safe Switch. It also tells you if a LoRA fine-tune pays for itself.
Who pays: B2B SaaS teams cutting LLM bills, and consultants selling migration audits. Hypothesis: $49/mo self-serve, $199/mo agency.
Runs fully local (no hosted link, by design: your data never leaves your machine):
