Cloudflare launches Clef and Clef-flash decision models (Qwen-based)

Cloudflare released two decision models, Clef (based on Qwen3.8-27B) and the smaller Clef-flash (Qwen3.5-9B), which output probability-weighted choices for predefined answers so downstream agents can act automatically. The company says both support text and images, report median latencies of ~209 ms (Clef) and ~39 ms (Clef-flash), are compatible with TypeSafe AI's Jev API, available on Hugging Face under Apache-2.0, and will be accompanied by a reinforcement-learning service for customer fine-tuning.

AREX-2 paper introduces long-horizon reflective training for self-improving LLM agents

AREX-2 (arXiv:2609.38288v1) describes training LLM agents built on Qwen3.8-27B using synthesized long-horizon improvement trajectories from machine-learning and algorithmic programming tasks to teach reflection and sustained iterative improvement. The paper reports strong results (MLE-bench Lite 81.8; Frontier-CS 70.7) and transfer to research benchmarks (BrowseComp 84.0; HLE 52.6; GAIA 92.2; DeepSearchQA 93.8), with performance that continues to improve as iteration budget grows.
