The Jev category doubles (again): AWS Strands Decider 2B open-sourced, Cloudflare ships Clef
From the AI digest for 2026-10-02
AWS released Strands Decider 2B (Oct 1, search feed): a 2B-parameter decision model, released as the category's entry with weights, training recipe, and evaluation — fully open-source — positioned as a Jev analogue. Same window, one day earlier (Oct 1 ~9:52 PM ET, X layer): Cloudflare-trained decision models "Clef and Clef-flash" (blog post; "never seen an idea spreading so fast" — the RT is right). And the copycat-wave writeup hit (WSJ-grade): three-week-old Jev is "sparking copycats" and LLM-alternative talk in Silicon Valley.
What's genuinely new: openness is now the table stakes, not the wedge — Perplexity opened the door yesterday (pplx-decider-v1-27b), AWS followed with recipe included, and Cloudflare's edge network joins as a distribution decision-model owner. The runner question is now seven-way (Jev vs AnyJev vs GLiClass vs d1 vs OpenAI Decisions API vs pplx-decider vs Strands/Clef) — still no independent comparative run of any of them on the same workloads.
Watch: the seven-way runner; whether AWS's open weights + recipe force Jev's pricing ($0.042/M) materially down.
