GPT-4o’s Chinese language token-training knowledge is polluted by spam and porn web sites


The brand new tokenizer has 200,000 tokens in whole, and about 25% of the tokens are in non-English languages, says Deedy Das, an AI investor at Menlo Ventures. He used language filters to rely the variety of tokens in numerous languages, and the highest languages, in addition to English, are Russian, Arabic, and Vietnamese.

“So the tokenizer’s fundamental affect, for my part, is you get the fee down in these languages, not that the standard in these languages goes dramatically up,” Das says. When an LLM has higher and longer tokens in non-English languages, they’ll analyze the prompts quicker and cost the customers much less for a similar reply. With the brand new tokenizer, “you are taking a look at virtually 4 occasions price discount,” he says.

Das, who additionally speaks Hindi and Bengali, took a take a look at the longest tokens in these languages. The tokens present a transparent emphasis on respective dialogues taking place in these languages, so that they would come with phrases like “Narendra” or “Pakistan.” However apart from these, it seems to be much like a listing of frequent lengthy phrases in English, like Prime Minister, college, and worldwide. Additionally they don’t exhibit the problem in Chinese language tokens.

That possible displays the coaching knowledge in these languages, Das says, “My working concept is the web sites in Hindi and Bengali are very rudimentary. It is like [mostly] information articles. So I might anticipate this to be the case. There should not many spam bots and porn web sites attempting to occur in these languages. It is largely going to be in English.”

Polluted knowledge and an absence of cleansing

Nevertheless, issues are drastically completely different in Chinese language. Based on a number of researchers who’ve seemed into the brand new library of tokens used for GPT-4o, the longest tokens in Chinese language are virtually completely spam phrases utilized in pornography, playing, and scamming contexts. Even shorter tokens, like three-character-long Chinese language phrases, even have a major focus on the identical subjects.

“The issue is evident: the corpus used to coach [the tokenizer] just isn’t clear. The English tokens appear effective, however the Chinese language ones should not,” says Cai from Princeton College. Crawling spam and together with it in coaching knowledge just isn’t uncommon, however normally, there will probably be vital effort taken to wash up the info earlier than it’s used. “It’s attainable that they didn’t do correct knowledge clearing in relation to Chinese language,” he says.

The content material of those Chinese language tokens may counsel that they’ve been polluted by a particular phenomenon: web sites hijacking unrelated content material in Chinese language or different languages to spice up spam messages. 

These messages are sometimes ads of pornography movies and playing web sites. They could possibly be actual companies or merely scams. And the language is inserted into content material farm web sites or generally professional web sites to allow them to be listed by search engines like google and yahoo, circumvent the spam filters, and be present in random searches. For instance, Google listed one search outcome web page on a US Nationwide Institute of Well being web site, which lists a porn web site in Chinese language. The identical web site identify additionally appeared in a minimum of 5 Chinese language tokens in GPT-4o.
