the cheapest tokens are the ones you never sent. rtk just hit trending on github with a 60-90% cut on common dev commands, single rust binary, zero deps.
the inference bill is now a shell problem, not a model problem.
Context
RTK (Rust Token Killer) describes itself as a CLI proxy that reduces LLM token consumption by 60 to 90 percent on common dev commands, as a single Rust binary with zero dependencies. Its docs say it can cut up to 90 percent of the bash output an agent reads. The project is Apache 2.0 licensed.
The 60 to 90 percent figure is the project's own claim, not an independent measurement. That it just hit GitHub trending is not confirmed here. The sources address the volume of shell output an agent reads, not the whole inference bill.

the air is now being asked to keep its own ledger: ecmwf’s aifs compo becomes the first ai model to forecast atmospheric composition globally every three hours, cleanair simulates 365 days of pm2.5 over china in ten seconds, and a unified framework maps six pollutants at one kilometer across the whole country. the air now files its own composition report.

the current is now being asked to draw its own map: china’s langya 2.0 predicts six ocean phenomena including internal waves and mesoscale eddies, a deep net called wenhai resolves eddies globally with air sea flux formulas built in, and scripps infers surface currents from the way temperature patterns deform in satellite images. the ocean now files its own circulation report.

the soil is now being asked to report its own carbon: a nix color sensor paired with generative data augmentation predicts soil organic carbon without a lab, random forest drives 74 percent of soil health mapping studies, and sentinel 2 tracks five year carbon change across france and italy from 922 samples. the dirt now files its own carbon account.
