RTK is a free GitHub plugin that compresses command outputs earlier than they attain Claude’s context window. Customers report saving 60 to 95 % in token consumption. Learn to set up it in three minutes and begin decreasing your AI prices in the present day.
Should you use Claude Code, Codex, or any AI coding device with Claude, you’re most likely spending extra on tokens than you’ll want to. A free plugin referred to as RTK can compress your command outputs earlier than they hit Claude’s context window. This implies shorter classes, higher reasoning, and considerably decrease prices.
The financial savings are actual. Customers working RTK report token effectivity charges between 57 and 65 %, which means they save that share of tokens on each command. Some instructions see financial savings as excessive as 97 %.
This information exhibits you precisely find out how to set up RTK, why it really works, and find out how to measure your financial savings.
What Is RTK and Why It Issues
RTK is an open-source GitHub plugin designed to compress command outputs. Whenever you run instructions inside Claude Code or different AI coding environments, these command outputs get despatched again to Claude as context. Each token in that context prices you cash.
RTK intercepts these outputs and compresses them intelligently. It removes pointless textual content, condenses verbose outputs, and retains solely the helpful info. Claude nonetheless understands what occurred, however makes use of far fewer tokens to do it.

Actual Token Financial savings
Whenever you run RTK achieve in your terminal, it exhibits you precisely what number of tokens you’ve saved. Actual customers report:
- 61 % token effectivity on common
- 120,000 tokens saved in a single session
- Constant 57 to 65 % financial savings throughout a number of runs
- Some particular person instructions saving 97 % of tokens
Should you’re on Claude’s professional plan at $20 monthly or utilizing Codeex, these financial savings add up rapidly. You’ll be able to run extra coding duties, longer classes, and experiment extra with out burning by means of your month-to-month credit.
How you can Set up RTK in Three Steps
RTK installs in minutes. You might have two choices: command line or Homebrew.
Possibility 1: Command Line Set up
Open your terminal and run this one-line command:
This downloads and installs RTK routinely. You’re carried out.
Possibility 2: Homebrew Set up
Should you use Homebrew on Mac or Linux, run:
On Home windows, use PowerShell and run the identical command. Homebrew works throughout all techniques now.
After set up, confirm it labored by working:
Your terminal will present your present token effectivity fee.
How you can Join RTK to Claude Code
Merely including RTK to your config file prompts it. Right here’s how:
For Claude Code, add RTK to your Claude Code config file. The method is easy. It’s possible you’ll must restart Claude Code for the modifications to take impact.
RTK will then routinely prefix bash instructions with its compression course of. New classes routinely use RTK with none extra steps from you.
For Codeex and Open Code, observe the identical course of. The RTK plugin installs itself into your config information. Restart your editor, and RTK is lively.
You’ll see a notification confirming RTK is related and able to compress instructions.
Measuring Your Token Financial savings
RTK offers you 3 ways to see what number of tokens you’re saving.
Methodology 1: Terminal Instructions
Run this in your terminal:
This exhibits your token effectivity share and complete tokens saved. It updates each time you run the command.
Methodology 2: Ask Claude Instantly
Inside Claude Code, ask Claude: “What number of credit did I save with RTK?”
Claude pulls your RTK information and exhibits you:
- Whole tokens saved
- Share discount
- Variety of instructions processed
- Your greatest particular person wins
For instance, an actual consumer asking this query bought again: 61.6 % discount with 169,000 tokens saved throughout 447 instructions.
Methodology 3: Headroom Dashboard (Non-compulsory)
Headroom is a companion device that gives a visible interface. It runs on port 8787 and exhibits credit score utilization on a dashboard. Nonetheless, it provides additional overhead and connection points. Most customers skip Headroom and simply use the RTK terminal command as an alternative.
Why RTK Works So Properly
RTK succeeds as a result of Claude’s context window accepts giant quantities of data, however Claude nonetheless processes each token. Command outputs are sometimes verbose and repetitive. They include:
- File paths you don’t want
- Standing messages that don’t have an effect on the result
- Duplicate info
- Formatting and line breaks
RTK compresses these intelligently. It removes the noise whereas maintaining the which means. Claude understands the compressed output simply in addition to the unique, however processes it in a fraction of the tokens.
For instance, a command that usually outputs 1,000 tokens would possibly compress to only 30 tokens. The knowledge continues to be there. The reasoning nonetheless works. You simply paid for 30 tokens as an alternative of 1,000.
Actual-World Token Financial savings Breakdown
One consumer working Claude’s Sonnet 5 mannequin reported these financial savings:
- Session token effectivity: 61 %
- Tokens saved in a single session: 120,000
- Largest single command win: 97.8 % saved
- Instructions processed: Dozens in a single session
One other consumer on Open Code with GLM 5.2 mannequin noticed:
- Token effectivity: 57.8 %
- Tokens saved: 169,000
- Instructions processed: 447 throughout the session
These aren’t theoretical financial savings. These are precise tokens that didn’t get billed.
At $3 per million enter tokens on Claude’s professional plan, saving 120,000 tokens is value $0.36 per session. Should you code each day, that’s over $100 per 12 months simply from one session’s enchancment. With RTK, you’ll see related financial savings each single day.
RTK In comparison with Options
There may be one different device referred to as Caveman, which is a customized ability you put in in your coding setting. Caveman additionally compresses tokens and reduces prices.
Nonetheless, RTK is the extra widespread alternative. It has extra GitHub stars, extra customers, and easier set up. Most builders who strive each want RTK.
RTK additionally integrates immediately into Claude Code, Codeex, and Open Code with out requiring extra setup. Caveman requires extra handbook configuration.
What Fashions Work With RTK
RTK works with any Claude mannequin:
- Claude Sonnet 5
- Claude Opus 4.8
- Any Claude variant in Claude Code
- Open Code fashions like GLM 5.2
- Any mannequin you entry by means of Codeex
The compression precept works the identical approach no matter which mannequin you employ. Heavier fashions like Opus see related share financial savings to lighter fashions like Sonnet.
