Ask HN: Cursor is using 269,738 tokens to edit 1200 token file

5•sarpdag•6mo ago
I started to track my Cursor usage via https://cursor.com/dashboard?tab=usage.

The pricing and usage of tokens hugely changed recently. To test I gave a simple task to Cursor which would use a 192 line swift code, including comments. This file has 1213 tokens according to https://platform.openai.com/tokenizer .

Here is my prompt: "There is a bug when i click on a raw it plays the audio and it deletes it afterwards, even though without clicking the delete button."

The Cursor dashboard says it used 269,738 tokens, and records to usage accordingly. I am a pro plan user.

Is there anyone else having similar issues?

All raw events > View > Tokens tab

Most of the tokens are cache read and cache write. It's possible that it's searching the whole codebase with these. My guess is they're embeddings tokens which are substantially cheaper.

Your 1213 should be somewhere in the input column. Probably less because of the caching. This is the magic where your $20 goes for more than $20 worth.

sarpdag•6mo ago
Actually they are charging for 269000 tokens. Looks like they changed how they charge accounts.

Cursor Version: 1.2.4 (Universal)

muzani•6mo ago
There's the Tokens tab on the mid-right, which is more detailed pricing. Not all tokens are the same price.

But the Usage at the top is a clear view too. On Claude sonnet-thinking, you've used $10 worth. 10k input (your prompt and code), 185k output (presumably written code, maybe thinking tokens too). ~900k cache write is probably it indexing the code and 14m cache read is it understanding/scanning your code.

bn-l•6mo ago
I’ve noticed this as well. You’ll get the cache discount but it’s still a weirdly huge number and probably a bug.

It would be even sadder if the rug pull was because of a bug they didn’t even realise was churning through tokens.
