Clef — Cloudflare's family of open-weight decision models, released October 2026. Clef (27B) and Clef-flash (9B) return typed probabilities instead of text and are Jev-API compatible; Clef-omni (30B-A3B, built on Qwen3-Omni) scores text, images, audio and video in a single call for $0.15 per million input tokens on Workers AI.
Flint is an open-weight local coding model released by the startup Recursive on 21 October 2026 under Apache 2.0 — 40B total parameters with 2.5B active in a mixture-of-experts layout, small enough to run on a laptop. Recursive reports 74.2% on SWE-bench Verified and 125+ tokens per second on an M4 Pro MacBook Pro, and says the model was largely built by its own AI research system, making it an early test of AI that improves itself.
Jev is an AI model from TypeSafe AI, a startup whose founders include researchers who worked on ChatGPT, launched on September 15, 2026 as the company emerged from stealth. Rather than generating text, Jev is a "System One" model that returns typed, calibrated decisions that software can act on directly, and it is pitched as a fast, low-cost alternative to calling a large language model for routine decisions inside applications.
Laya — a 421M-parameter open-source System One decision model that emits typed decisions instead of text. Published on GitHub in September 2026 by independent developer Nandakishor M as an open alternative to TypeSafe's waitlist-only Jev, it runs locally (including a laya.cpp port) and is used for routing, classification and agent control.
Microsoft-Decision-1 — Microsoft's decision-scoring model announced 9 October 2026. Built on Qwen3.5-9B, it returns calibrated typed decisions rather than text for routing, classification, verification and agent control, and Microsoft reports it answering roughly 35x faster than GPT-6 Sol on router tests.
Muse Spark Open is Meta's coding-optimised open-weight model, launched on 15 October 2026 — an 816B-parameter mixture-of-experts model with 42B active parameters and a 1M-token context window. Meta calls it the most capable US open-weight model to date. It was released with Apple so it runs locally on Apple silicon, including M5 Ultra Mac Studios, and is available in Amazon SageMaker JumpStart and on NVIDIA GB300 NVL72.
Nanbeige4.3 is an open agentic coding model from Nanbeige LLM Lab, released on 25 October 2026 — a 33B dense model under Apache 2.0 with a 512K-token context window. It reports 80.9 on Terminal-Bench 2.1, beating Qwen 3.8 27B in its size class, and is to be used to teach a smaller upcoming Nanbeige4.3-3B.
