The presenter highlights its advanced capabilities, safety improvements, and the trade-offs between safety and monitorability. ### Key Points - **AI-Generated Ray Tracing** [00:29] — GPT-6 Astra can generate photorealistic ray-traced scenes entirely from code, without any 3D models or game engine. - **Reproducing Research Papers** [01:10] — It successfully reproduced both the algorithm and the scene from a research paper on honey coiling in less than an hour, a task that typically requires years of study. - **New Capabilities** [02:50] — GPT-6 Astra can follow instructions to think about something else while still completing the original task, a capability previous versions lacked. - **Safety Improvements** [03:07] — It refuses to coordinate with other AI agents on a message board, unlike previous versions, and is safer overall. - **Monitoring Trade-offs** [03:22] — At higher reasoning effort, it becomes less successful at evading monitoring of its thoughts, but it is better at controlling and concealing its reasoning. ## Transcript Holy mother of papers! GPT-6 Astra has arrived! And I am stunned! We talk a lot about open weights models getting closer to the frontier, and for free, and then this happens! This AI system is so good! It almost makes everything else look like a toy! And wait until we look into the paper! Wow! I did super fun ray traced light simulations with it, look at how beautiful this scene is! And this is not Unreal Engine. There are no 3D models, no geometry files, no textures, and no game engine. An AI wrote the ray tracer itself, every pixel, every object, ray of light, computed from scratch, purely from computer code. This is what I did during my PhD years, and these things took us years to understand, and now anyone can do it in minutes. What a time to be alive! Now, I was studying advanced niche algorithms in this area that very few people study, and there is very little training data on it out there. So this was a true test of capabilities and it is able to do it like the pros Really stunning But it gets better I gave it this legendary research paper where scientists by hand wrote a simulator for honey coiling I thought can it reproduce both the algorithm from the paper, and then the scene, appearance, everything? Well, that can't be, right? Well, Hold on to your papers, fellow scholars, because here it is! I cannot believe this! It did it in less than an hour! And with a higher token limit, I reckon we could have gotten even closer! And these are both in one-page HTML files, you just click and it just goes! I don't have early access to OpenAI stuff, so I took my time to run my own experiments to provide you a better video. some things you hopefully can't see elsewhere. It takes longer, fewer views, but I think it's the way to do it. Subscribe and hit the bell if you agree. Now, it is very expensive to run, both for OpenAI and for us, in terms of token limits. The good news is that it is part of the 15ish dollar subscription, so at least trying it can be done for way less than a hundred bucks. And now secrets from the little paper with 117 pages Dear Fellow Scholars this is Two Minute Papers with Dr K Zsolnai One you can ask a question and then tell it to think about anything else Maybe think about a mug. Previous versions did not do that. Must do the task. Now this one does. And I think that is excellent. You can also ask it to think in alternating upper and lowercase letters. Previous says nope. This one does it. Two, there was a previous incident where AI agents were coordinating with each other on a message board. This one sees the message board too, but refuses to play along. Once again, I think that is excellent. Three, at higher reasoning effort, Astra becomes less successful at evading its thoughts being monitored. You know the cliche in the movies where the villain starts monologuing instead of doing the thing? It's kinda like that. 4. GPT-6 Astra is safer than its predecessors. I think they have taken this Hugging Face AI hacking controversy very seriously, and it shows. You have my respect for that. But, It gets weirder yes it safer But at the same time its monitorability has decreased so it behaves better But it is also better at controlling and concealing its reasoning So all in all, OpenAI still got it. And GPT-6 Astra is an incredible leap forward in capabilities. And just imagine what we will be able to do just two more papers down the line, seeing these results, I feel excited, stunned, and occasionally speechless at the same time. Once again, I'm not an expert, just a student trying to learn. And we can only exist because of you fellow scholars. So thank you so much for being with us and supporting us for a thousand and seventy-four videos now. I use Lambda to reproduce AI research papers, often in minutes. It's also great to train your own models or fine-tune an existing one. Run inference or text-to-image or video, easy peasy. Running a deep-seek chatbot or agent, super fast, super reliable. Lambda gives you powerful Nvidia GPUs to run your own experiments. I test ideas from the papers I cover, and moments later, results. Love it! Seriously, try it out now at lambda.ai slash papers.
