JetBrains benchmark finds RTK token compression tool shows 7.6% cost increase on Claude Code

JetBrains benchmarked Rust Token Killer (RTK), a compression proxy for Claude Code, and found it increased token costs by 7.6% at low reasoning effort (p=0.004) with no measurable change at high effort, contradicting RTK's advertised 60-90% savings. Task quality remained unchanged in both test arms, according to the JetBrains AI blog.
