RT to help Simon raise awareness of prompt injection attacks in LLMs. Feels a bit like the wild west of early computing, with computer viruses (now = malicious prompts hiding in web data/tools), and not well developed defenses (antivirus, or a lot more developed kernel/user space security paradigm where e.g. an agent is given very specific action types instead of the ability to run arbitrary bash scripts). Conflicted because I want to be an early adopter of LLM agents in my personal computing but the wild west of possibility is holding me back.

If you use "AI agents" (LLMs that call tools) you need to be aware of the Lethal Trifecta Any time you combine access to private data with exposure to untrusted content and the ability to externally communicate an attacker can trick the system into stealing your data!

I just posted the first of what will be several chapters about transformers, which in the last year has been the most requested topic for the channel. youtu.be/wjZofJX0v4M

I wrote a very long post on what a machine learning artifact is, how files work, safetensors, pickle, and a lot more, as a way to understand GGUF. Thanks especially to everyone in this thread who added historical context around safetensors. vickiboykis.com/2024/02/28/g…

Continuing digging deep on GGUF. Anyone have information/oral history of how we went from pickle in pytorch to safetensors, with explicit details around what actually is in a .pt file/state dictionary? Yep, I've looked at all the code/docs, I'm now looking for commentary

Evaluating LLMs is HARD, so I'm excited to share a bit of what we've been working on at @MozillaAI from the NeurIPS 1 LLM 1GPU 1Day challenge last fall. The write-up includes background on eval repo with sample K8s infra. More soon! blog.mozilla.ai/exploring-ll…

New YouTube video: 1hr general-audience introduction to Large Language Models youtube.com/watch?v=zjkBMFhN… Based on a 30min talk I gave recently; It tries to be non-technical intro, covers mental models for LLM inference, training, finetuning, the emerging LLM OS and LLM Security.

There's wide consensus on this idea
Whenever a person justifies some argument with “people say” or “community Y says”, don’t believe them. Ask for specific names and talk to them yourself. In my experience 95% of the time they don’t actually believe what the original person was claiming.

True, personally, I think the best and shortest definition is that "Embeddings are learned transformations to make data more useful" from Roy Keyes. But a few examples like in Simon's blog post help illustrate the useful part. roycoding.com/blog/2022/embe…

If you're puzzled at why there's so much activity around "vector databases" at the moment, understanding embeddings should answer that question too
