In Gemini at least, if you look at how they process PDFs, they do an OCR and then feed the text + image to the model, without charging you for the text tokens (I believe).
So my guess is that Claude’s backend is doing the same — so this hack is probably more of a loophole in token accounting that might get closed if Claude is doing what Gemini does

I tried the same thing last year (with openai models), back then it worked to reduce prompt tokens, but you needed way more completion tokens, ultimately more expensive (and slower)

What, you don't like your caveats to be honest?

This seems like a pricing hack that burns resources, that when the loophole gets closed the price of OCR will have to rise?

It’s not a loophole, it just happens that encoding information as optical tokens is much more efficient than text.

Truly a picture is worth a thousand words.

Of course it isn't
A text encoding uses 8bits per character on average, tokenization further compresses that
An image font would be 25 bits if 5x5, and most fonts are 12 pixels high
Of course it isn't efficient, this is a pricing inefficiency and a hack to exploit it (even the author describes it as an exploit)

You are wrong.
Text tokens are high-dimensional vectors, not 8 bits per character. Every token has a deep embedding, e.g. 1024 float values per text token.
DeepSeek-OCR proved 10x+ compression from visual embedding of text, which was a groundbreaking result. [1]
Very cool to see OP's project hacking on this principle. It's still not lossless, as noted in the github, but is a promising research direction.
Not really. They arent actually using more resources this way either. This might be a fundamental inefficiency thats being removed
It kinda makes sense too. Because while people do read code word by word, we often "glance over" it and do roughly pattern recognition on it to know what it does. Only homing in on something when we need to answer a specific question. I think humans kinda naturally do this exploit anyway
