Snowflake's CoCo Cuts AI Agent Costs by 33-45% with Three Harness Techniques
StasBekman · x · 2026-08-26
Snowflake AI Research presents improvements to its AI coding agent CoCo and CoWork, achieving 33-45% lower cost per trial in end-to-end benchmarks with comparable or better reliability.
- Problem: In long data-analysis sessions, tool schemas, skill catalogs, raw tool results, and conversation history can be re-read every turn, causing context bloat that increases cost and hampers focus.
- Solutions:
- On-demand tool and skill loading: Retrieve only what the current step needs, removing 79K tokens from processing.
- Two other techniques further reduce context processing.
The work emphasizes that agent cost is not solely a model problem but also a context management issue.
