AWS bolts together open source agent harness, says it sips fewer tokens than rivals

The AWS Strands Agents team has released Strands harness, a general-purpose, open-source agent harness available for Python. Designed to bridge the gap between prototype and deployment, it runs locally or on cloud providers. AWS claims the tool achieves comparable accuracy to Claude Code and Codex on benchmarks while utilizing 28% fewer tokens. This framework aims to help developers maintain agent performance when moving away from proprietary loops, though some reports note the benchmarks were internally conducted.
