TypeSafe's Jev: A Model That Can't Write but Decides, Claiming 200x Speed and 400x Cost Savings
rseroter · x · 2026-09-25
TypeSafe's Jev introduces a new model class that only classifies, scores, and routes — no text generation. TypeSafe claims up to 200x faster and 400x cheaper than LLMs on decision tasks; one test showed 85 vs 910 output tokens per yes/no answer. The O'Reilly piece argues a large share of LLM app components are decision tasks, so architecture choices may shift again.
