A blog post from Hacker News questions the effectiveness of Rust Token Killer (RTK), a tool designed to reduce AI coding costs by compressing terminal output. While RTK claims significant token savings, independent benchmarks using Claude Code and DeepSeek V4 Pro 0813 on the Terminal-Bench 2.1 dataset showed mixed results. For Claude Code, RTK offered a marginal 5% cost reduction, but pass rates slightly decreased. Conversely, DeepSeek saw a 5% cost increase and a 2% drop in pass rates, with task-level costs rising significantly. The analysis suggests that RTK's reported token savings do not directly translate to lower AI bills and can even lead to increased costs or reduced quality in certain scenarios. AI
