The day in AI
Amazon and Cloudflare released open-weight decision models built on Qwen to rival Jev
The day in brief
Amazon Web Services and Cloudflare each released open-weight decision models on 1 October, small models that return a scored choice from a fixed set of answers.
Amazon Web Services (AWS) released Strands Decider 2B, built on the Qwen3.5-2B language model with text generation removed. It picks one answer from a closed set and gives a calibrated confidence for that pick. It follows the design of Jev, the decision model from TypeSafe. It comes out through Strands Labs, a project started by Marc Brooker, an AWS distinguished engineer. AWS says it's meant for agent workflow steps that don't need a full LLM, at lower latency and cost, and it runs locally.
SQ Magazine reports a median decision latency of about 115 milliseconds on a single Nvidia RTX 3090. The same report places it third of 33 models in its size class on JevBench, which scores accuracy and calibration together.
Cloudflare released Clef and Clef-flash on the same day under Apache 2.0. They are the first models trained by its Workers AI team. They answer yes or no, multiple choice and score questions with probabilities. Clef is post-trained from Qwen3.8-27B and Clef-flash from Qwen3.5-9B. Each reads the prompt in one prefill pass and then makes the decision in a single non-autoregressive step, so it doesn't generate an answer token by token. Both accept images, have a 64k context window and work with the Jev API.
Cloudflare reports a median latency of 209.3 milliseconds for Clef and 38.8 milliseconds for Clef-flash across 43 benchmarks. On the same tests it puts Jev at 524.1 milliseconds. Clef costs $0.24 per million tokens on Workers AI, and The Register puts Jev at $0.042 per million tokens. Cloudflare also announced a reinforcement learning (RL) fine-tuning product for Clef.
Black Forest Labs released FLUX 3 Image as a closed API. It takes scene layouts as JSON bounding boxes with element ids, and edits leave pixels outside the box numerically unchanged. Black Forest Labs reports that 67.8 to 89.7% of pixels stayed identical across edits. Output is native at about 4K and it accepts up to ten reference images. It starts at about $0.0205 per 768 pixel image, with an introductory 50% discount until 8 October. An open-weight version is said to be expected within weeks.
The decision model numbers have no independent check yet. Amazon's figures come from a press report and Cloudflare's come from its own testing, so the two have not been compared on the same benchmark.
