Karpathy 让 Opus 5 花 10 美元做了个《指环王》3D 渲染，5500 行代码，还聊了模型短板。
Andrej Karpathy 用《指环王》第一段做测试，给 Opus 5 提供 100 万 token 预算（约 10 美元）和 three.js 渲染任务。Opus 5 用约 2 小时写了 5500 行代码，程序化生成故事场景，结果有点粗糙但能跑。Karpathy 认为 LLM 目前无法直接观看视频或玩游戏，只能靠截屏检查效果，因此出错不少。他设想按需生成'临时版 GTA'式的定制 3D 世界。
AJ 这 3D 渲染测试确实比鹈鹕骑自行车靠谱多了👍
AJ 这 3D 渲染测试确实比鹈鹕骑自行车靠谱多了👍 Andrej Karpathy @karpathy We're starting to leave the territory where you'd test an LLM by e.g. "create an svg of pelican on a bicycle". As one idea to generalize it, I was interested what Opus 5 would do if I gave it the first paragraph of the Lord of the Rings, a 1M token budget (~$10) and asked for three js render of it. Opus went off for ~2 hours and wrote 5500 lines of code that (procedurally) rendered the story. It's kind of janky but fun. But it's a bit mindboggling that the LLM has to place and orchestrate various polygon assets in (x,y,z) coordinates and write code that animates it all, and that it even does anything at all. I also like this kind of examples because no one in their right mind would ever spend the time to write something this custom but LLMs have all the stamina and patience in the world, so it's an example where we go from "no one would ever do this" to "sure, why not, it's ~free". There might be a lot more. But I'm excited about creating hyper custom worlds that you can imagine dropping players into, e.g. here to participate in the LoTR story as a spectator NPC, or one of the characters, or etc. Something like an ephemeral GTA of X on demand. Last thought is that the domain of worlds/games exposes a weakness in LLMs: they can't easily audit their work because they aren't able to efficiently and natively perceive videos or play games within them. Here, Opus 5 had to very slowly and painstakingly take screenshots at different points, and it messed up a few times and created a bunch of jank. An example of raw capability (multimodal, gameplay) that I think is still quite lacking. Your browser does not support the video tag. 🔗 View on Twitter 🔗 View Quoted Tweet 💬 8 🔄 0 ❤️ 8 👀 3319 📊 6 ⚡
