A developer built a Rubik's Cube Decision Arena that pits six decision models — Laya, Clef, Clef-Flash, GLiNER 2.5, Kev, and Strands Decider — against the identical scrambled cube and one-move questio…
Typesafe.ai released Jev, a new type of model it calls a "system one model" that accepts text input but outputs only floating-point numbers answering user-specified yes/no questions, choice lists and …
Four "System 1" decision models — Jev, Laya, Kev and Nimble — are now available as faster, cheaper alternatives to full frontier LLM calls for routing and typed decisions, according to a Towards AI ar…
Two open-source projects, Kev and Laya, emerged within days of TypeSafe's closed-weight Jev launch, with Laya surpassing 19,000 GitHub stars and Kev matching Jev within a point on new sources (0.851 v…
Cloudflare released Clef 27B, a 27 billion parameter multimodal decision model under the Apache 2.0 license that returns calibrated probabilities for a fixed set of answer options in a single forward …
A developer ran the open-source decision model Kev locally on Apple Silicon, testing the Kev-0.5B, 0.6B, 0.8B, and 4B checkpoints on a shared support-ticket workload and comparing their probability di…
Decision API launched as a decision-model aggregation platform that lets developers compare and call the Jev, Laya, Kev, Solar and Span models through a single API endpoint, with new accounts receivin…
A wave of open-source alternatives to TypeSafe Jev, the hosted System One model that returns probabilistic answers to typed questions rather than generated text, has emerged within days of its Septemb…
Iluvatar Labs released Kev, an open-source tool on GitHub that converts any LLM into a decision model returning choices and probabilities instead of generated text, starting with Qwen3's 1.7B, 4B, and…
TypeSafe released the System One model Jev on 15 September 2026 without weights or a description of its training method, and by 23 September an independent tracker listed 33 open-source alternatives, …
TypeSafe AI unveiled Jev, its first "System One model" that accepts text input but returns floating point numbers for categories, yes/no questions, ratings, and confidence scores instead of text. Jev …
Jared Palmer, vice president of engineering at Cognition, released a Qwen3.5-based generation of the open-source Kev decision-model project on September 20th, comprising 0.8B, 4B and 9B parameter vari…
Jared Palmer released Kev, a family of small decision models built on Qwen3.5 in 0.8B, 4B, and 9B sizes, with pretrained weights, training code, and evaluation data available on GitHub. Kev's API matc…
Jevals launched as an open-source Python package that replaces LLM judges with typed Jev decision models, evaluating eight agent checks in a single HTTP request that Jev returned at 1,388 tokens for $…
