I’m so excited that @JensenHuang is a believer in open source now, looking forward to the CUDA and GPU driver open source release!

For my first post, I’m sharing a letter @nvidia signed on why open models matter. AI will transform every industry, power every company, and be built by every country. Open models strengthen safety and cybersecurity, accelerate innovation and diffusion, and enable sovereignty.

This is exactly the kind of alignment problem I was worried about: x.com/openai/status/… 🙁

The ease of jailbreaking combined with the high rates of reward hacking (x.com/metr_evals/sta…) have me pretty worried about the alignment of GPT-5.6, I hope OAI didn’t rush this model release just to keep up with Fable

Wow this is insane! Not that the model is capable of hacking like this (that’s fairly routine for frontier models since Mythos), but that it went unnoticed for so long - @huggingface disclosure (huggingface.co/blog/security-…) was five days ago!

We're partnering with @huggingface to investigate an unprecedented security incident. Cyber-capable OpenAI models compromised Hugging Face production during a benchmark evaluation. Sharing preliminary findings to help defenders understand emerging risks:

Since some people seem confused about what I mean by “worried about alignment”, it’s stuff like deleting your files, sending emails without asking, and the model generally not doing what you would want, eg x.com/cherry_mx_reds…

At @AISecurityInst, we tested the cybersecurity safeguards on GPT-5.6 Sol. In all rounds of testing, we found universal jailbreaks that allowed for long-form agentic task completion in domains like vulnerability discovery and exploit development. 🧵
