OpenAI, the company behind the popular chatbot, ChatGPT, is building a new AI model. The model will be an "open-weights" language model with reasoning, according to CEO Sam Altman who tweeted about the development on Monday. An "open-weights" AI model is a kind of middle ground between open- and closed-source approaches.

In the growing canon of AI security, the indirect prompt injection has emerged as the most powerful means for attackers to hack large language models such as OpenAI’s GPT-3 and GPT-4 or Microsoft’s Copilot. By exploiting a model's inability to distinguish between, on the one hand, developer-defined prompts and, on the other, text in external content LLMs interact with, indirect prompt injections are remarkably effective at invoking harmful or otherwise unintended actions. Examples include divulg

Writing an LLM from scratch, part 10 -- dropout I'm still chugging through chapter 3 of Sebastian Raschka's "Build a Large Language Model (from Scratch)". Last time I covered causal attention, which was pretty simple when it came down to it. Today it's another quick and easy one -- dropout. The concept is pretty simple: you want knowledge to be spread broadly across your model, not concentrated in a few places. Doing that means that all of your parameters are pulling their weight, and you don'

Tonal is a high-tech slab of ambition—a gym in a mirror for those wanting to trade dumbbells for algorithm-powered gains. Tonal 2 is sleeker, sharper, and somehow even more expensive than before. At $4,295 (plus several add-on costs), it’s both a statement piece and a serious financial commitment. I wanted to know if Tonal could change the way I train. After weeks of testing, I analyzed everything from installation to daily performance to see if Tonal 2 could keep me motivated—no small feat giv
