What Jev Is [October 2026]: The AI That Generates No Text — How to Use It, Pricing, and How It Differs from Microsoft-Decision-1

On 9 October 2026, Microsoft released Microsoft-Decision-1, a decision model at the same price as Jev ($0.042 per million input tokens, free output) and with the same question types. This article explains what Jev — released by TypeSafe AI on 15 September 2026 — is: a System One model that generates no text and returns Choice (classification), Score (rating) and Noul (a 0–1 truth value) with probabilities; speculative fan-out, where stacking questions barely changes latency; how to get started from the waitlist to the Python SDK, HTTP API and Claude Code skill; routing low-confidence answers to people; and use cases. It then compares Jev with Microsoft-Decision-1 (access, context length, availability, Japanese support), explains which to choose and whether you can use them from Japan, and covers Jev's latest status in October (Series A, rate limits, OpenRouter listing). It also covers the official note that CJK accuracy is lower than English and the weak spots TypeSafe publishes itself.
