Does RTK output compression still cut AI coding costs? Team benchmarks it on Terminal-Bench 2.1
Bartaseth · reddit · 2026-09-12
The Quesma team validated RTK (Rust Token Killer), one of the most popular LLM output compression tools, to see whether it still makes AI coding cheaper with newer models. Setup: Claude Code with Fable 5.0, and OpenCode with DeepSeek V4 Pro 0813 via OpenRouter, both run on Terminal-Bench 2.1. Full methodology and results are on their blog — the core question being whether token-compression tooling still pays off as models get more capable.
