折腾了一段时间,我做的 Lomote 终于上线了。 想解决的问题很简单:生成图片、视频、3D 模型,做图片或视频增强、搜索相似图片时,不用在一堆工具之间来回切换。 在 Lomote 里,这些能力都可以通过工作流组合起来。 感兴趣可以试试:

Benchmark AI models by having them animate a 3D banana plant's full lifecycle.
fran-mora · HN
I gave 5 AI coding agents one prompt: grow a banana plant through its whole life in three.js: sprout, leaves, flower, fruit, rot, then pups that restart the loop. It's deceptively simple and yet very hard to get right from procedural code: you have to write working three.js and understand how the plant is actually built; how it hangs, ages and decays. Get the biology wrong and the code renders something weird. These are agents, not bare models (Claude Code and Codex for now). They can use tools, including playwright to check their work and improve it.
