Show HN: Slash-tokens – know LLM cost before the call leaves your machine (github.com)

1 points by wolfejam ↗ HN
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

good thing you replaced emdashes with double dashes, i almost thought this was AI generated /s
haha! they were on typewriters long before models!
How 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.
