- AWS Strands Labs dropped Strands Decider 2B, an open-source model that doesn’t chat—it decides. Built on Qwen3.5-2B, it swaps the text head for a pointer layer to spit out choices or yes/no probabilities in ~115 ms on consumer GPUs. No hallucinations, just calibrated confidence scores. It’s Apache-2.0, so you can run it locally without begging a hosted API for mercy. Perfect for routing agent tools or checking if your "investment" is actually a scam before you feed it more meat wallet funds. Accuracy hits 0.723 on JevBench, which is better than most regulators’ grasp of blockchain. If you’re tired of LLMs rambling about moon missions while burning your hash manifest, this is the efficient alternative. Just remember: it’s not magic, it’s math. And unlike the Chrome Syndicate, it actually delivers what it promises.
