AWS Ships Tiny Decider for AI Agents

🔥 What happened AWS dropped Strands Decider 2B, an open-source decision model built on Qwen3.5-2B that runs locally and picks from predefined options instead of generating text. It ships with calibrated confidence scores. Distinguished engineer Marc Brooker built it after seeing TypeSafe's Jev — and just days after OpenAI announced a rival. 💡 Why it matters Agentic workflows don't always need a frontier LLM to answer "what's next?" A 2B model slashes latency and cost while boosting reliability via closed-domain answers. Brooker's prototype briefly topped the Jevbench leaderboard for its size class. ⚡ Our take Frontier labs won't own this niche — building a competitive decider costs hundreds to thousands of dollars, not millions. TypeSafe's CEO fires back that rivals underestimate how hard real intelligence is. Both are right, and that's the story.
