In large language model (LLM) pretraining, data quality is believed to determine model quality. In this paper, we re-examine the notion of “quality” from the perspective of pre- and post-training co-design. Specifically, we explore the possibility that pre-training on more toxic data can lead to better control in post-training, ultimately decreasing a model’s output toxicity. First, we use a toy experiment to study how data composition affects the geometry of features in the representation space. Next, through controlled experiments with Olmo-1B models trained on varying ratios of clean and toxic data, we find that the concept of toxicity enjoys a less entangled linear representation as the proportion of toxic data increases. Furthermore, we show that although toxic data increases the generational toxicity of the base model, it also makes the toxicity easier to remove. Evaluations on Toxigen and Real Toxicity Prompts demonstrate that models trained on toxic data achieve a better trade-off between reducing generational toxicity and preserving general capabilities when detoxifying techniques such as inference-time intervention (ITI) are applied. Our findings suggest that, with post-training taken into account, bad data may lead to good models.

    It’s extremely useful for many things, if you know how to use it, and it’s annoying and useless for many others, which is what they fixate on and keep-jerk react to

      It’s annoying that every middle manager is trying to become the hero of their company by pushing it inappropriately into every single field at the expense of productivity and jobs, while simultaneously the largest most powerful companies are slinging their SaaS solutions built on stolen data which are destroying communities of both the physical and hobby varieties and consuming more natural resources than all the fucking crypto scams of the last like 10 years

      But yeah it’s neat I guess

      My gf’s employer was going into administration last month. AI was surprisingly competent in determining where to seek advice and had a decent understanding of what to expect and how to approach things such as not getting paid on time (which happened last week).

      Of course, we double and triple checked any information given to us with the relevant bodies, but it provided a little relief to go into something so chilling not being completely clueless.

      AI has its use, but you have to know how to extract the information you need.

      It’s stupid the way people are using it for therapy. Like, by all means ask it if it knows any organisations which can help you, then look those up, but don’t tell it a load of personal information about your relationship, because the reply will be something akin to the advice you see on r/relationships (which is probably where it scraped its data from) 😅

        Judges are warning lawyers there will be sanctions if they kept using LLM to do their research as documents with fake references keep appearing.
