Something you can actually use or run today.
On October 1, 2026, Strands Agents released Strands Decider 2B, an open-source model specifically architected for logical routing and tool orchestration.
It allows developers to use smaller, cheaper models for agent overhead, saving frontier models for actual task execution.
AILookup take
Specialized routing models are the correct architectural path for agentic systems. Using a massive general LLM for simple tool selection is an expensive mistake that this model helps solve.

Details
- Reduces latency and infrastructure costs by replacing large general-purpose models for routing tasks.
- Advances the trend of using specialized small models within multi-agent architectures.
- Provides a lightweight, open-source tool for efficient decision-making in agentic workflows.
Consensus
Sources agree on the model's release date, parameters, and its specific focus on decision-making rather than generation.
