TypeSafe launched Jev on September 15, 2026. It is a decision model, not a chatbot. You define the allowed answers, and Jev returns a label, a score or a yes/no probability. In about 4 weeks, at least 20 Jev alternatives shipped. They come from Cloudflare, OpenAI, Perplexity, Liquid AI, AWS’s Strands Labs and independent developers. This guide compares each one on size, license, hardware, pricing, Jev API compatibility and published benchmarks. TL;DR Size range: 287M (GLiNER2.5-multi-Decide) to 35B-A3B (Mapika Decider). Jev’s size is not disclosed. Runs on: Encoders like Von and Laya run on CPU. 4B adapters fit a 24 GB GPU or a 32 GB Mac. Performance: Most open models trail Jev on hard reasoning. Several match or beat it on narrow classification. Best: Cloudflare Clef scores 94.20 BANKING77 F1 versus Jev’s 79.74, per Cloudflare’s own run. Worst: Von 1.2 scores 0.422 accuracy in Respan’s run, against Jev’s 0.932. What is Jev, and why look for alternatives? Jev is TypeSafe’s first ‘System One’ model. You send a state, such as a ticket or log line. You also send typed questions: Choice, Score or Noul (yes/no). Jev scores every question in one parallel pass and generates no text. TypeSafe’s docs list $0.042 per 1M input tokens, with free output. Context is 64k tokens per request. Input is text only. Weights are closed, and access runs through a waitlist. TypeSafe’s workflow evals put Jev at 67.8% agreement and 0.4 s per case. That leaves 4 gaps developers keep raising: no images, no self-hosting, no published size and no fine-tuning. The 20 models below fill some or all of them. How should you read these benchmarks? Most figures below are self-reported. The suites differ: JevBench, Decision Index, typed-decisions and Respan’s behavior benchmark. Scores across suites are not comparable. The one multi-model third-party table comes from Respan, which sells a competing model. Hosted decision APIs 1. Cloudflare Clef and Clef-flash Cloudflare announced Clef on
