Show HN: Slash-tokens – know LLM cost before the call leaves your machine
I kept finding out what a call cost after I had already paid, so I built /Slash -- slash-tokens is a 4.8KB WASM that estimates tokens FAST and can block a wasted trip, or switch to cheaper same-provider model before the request leaves your machine. Try it MIT, no account needed: bunx slash-tokens
Or install the SDK: npm install slash-tokens
- ramon156 1mo agogood thing you replaced emdashes with double dashes, i almost thought this was AI generated /s
- wolfejam 1mo agohaha! they were on typewriters long before models!
- chrism238 1mo agoMove over Halting Problem!
- wolfejam 1mo agowe don't claim 100% -- we optimize, we don't offer perfect computation! The bill is after the call, it's a local estimate, so you can skip a wasted trip or use a cheaper model, same provider.
- brownbear7 1mo agoHow do you handle cached input or long-context pricing? Some providers change the rate a lot depending on that, so I’m curious how accurate the estimate stays.
