AWS open-sources Strands Harness: general agent with ~28% lower token cost
AWS released Strands Harness (Apache 2.0) — a ready-made general-purpose agent for Python/TypeScript that runs locally or in any Linux cloud, with shell/file/web tools, context compaction, memory, and subagents. On matching Claude/GPT models it claims ~28% lower token cost vs other harnesses across six benchmarks, and with Fable 5 it scored higher than Claude Code on Terminal Bench 2.1 at ~77% lower cost.
