A small model built for agent decisions

Strands Decider 2B is a 2-billion-parameter model positioned as a dedicated decision-making component for AI agents, released under an open-source license. Rather than generating long-form text, the model is intended to help autonomous agent frameworks choose among actions or routes — a step in agentic pipelines that typically requires fast, lightweight inference.

Open-source release

By publishing the model as open source, Amazon makes the weights available to developers building agent systems, aligning with the broader Strands agent tooling ecosystem. Details on benchmark results and licensing specifics were not included in the reviewed materials, and remain unconfirmed.

The claim that Amazon has released the open-source decision-making model 'Strands Decider 2B' for AI agents is True.
