Did you know that one base model is responsible for 94% of model-tagged NSFW AI videos on CivitAI?
This new paper studies how a small number of models power the non-consensual AI video deepfake ecosystem and why their developers could have predicted and mitigated this.

I appreciate this sympathetic position
people's feelings of emotional dependency on these "human-like" bots is real. ridiculing them doesn't help anyone

The problem is that it talks to you *as if* it is a person. If you're in a vulnerable state, I can absolutely see how you could be caused actual harm by engaging with these models.

💡Can we trust synthetic data for statistical inference?
We show that synthetic data (e.g., LLM simulations) can significantly improve the performance of inference tasks. The key intuition lies in the interactions between the moment residuals of synthetic data and those of real data

The exchanges between Adam and ChatGPT are devastating. This, in my mind, is the worst one.
One of his last messages was a photo of the noose hung in his bedroom closet, asking if it was "good." ChatGPT offered a technical analysis of the set up and told him it 'could potentially suspend a human."
