A '90% token savings' AI tool gets called an illusion. Its author confesses why (mroczek.dev)
RTK strips noise from command output before it reaches an LLM, advertising 60-90% savings. The article's core objection: that figure is the percentage of raw command-line text removed, not a cut to your actual API bill, and tool output is often a small slice of a session's tokens.
The thread split hard. One user saved 3k tokens across a 300k-token session; another saved 3.7M of 3.9M and shrugged 'tokens saved are tokens saved.' Then the author named the real trigger: management pushing the tool to cut costs, no accuracy benchmarks anywhere.
