一水 发自 凹非寺 量子位 | 公众号 QbitAI 李飞飞押注的世界模型领域,迎来两位自动驾驶大牛创业新成果! 无需任何游戏引擎,AI能以40毫秒/帧想象并实时生成视频。 40毫秒/帧啥概念? 人类眨一次眼都需要100~400毫秒,所以现在AI几乎可以一瞬间创造视频了。 而且无需高端显卡,玩家可以实时观看,并与AI生成的世界交互了。 就像是在 探索一个平行宇宙 的感觉~ 那么,新玩家Odyssey究竟有哪些亮点呢? 世界模型≠视频模型 一上来,Odyssey就在最新官方博客中解释: 世界模型≠视频模型 。 他们认为,乍一看世界模型好像是视频生成模型的完美应用,但后者的架构、参数和数据集实际上并不适用于前者。 而除了产品迅速引人关注,更值得说道的还是其背后研发公司。 两位联合创始人 Oliver Cameron 和 Jeff Hawke 均在自动驾驶领域有着深厚从业背景,虽然公司成立不到2年,但一亮相就获得了资本青 睐。 迄今为止,Odyssey已从EQT Ventures、谷歌GV和Air Street Capital等投资机构筹集了 2700万美元 (约合人民币1.9亿),皮克斯创始 人/图灵奖得主Ed ...
