零一万物发布 Yi 系列

2023 年 11 月，零一万物发布了 Yi 系列大模型。这家公司从官宣成立那天起就自带光环——创始人李开复，曾任 Google 大中华区总裁、创立创新工场，是中国科技圈最具辨识度的名字之一。当这样一位人物下场做大模型，市场对它的期待从一开始就高于一般创业公司。Yi-34B 的发布没有辜负这份期待：凭借较长的上下文窗口和扎实的中英双语能力，它登上了开源模型榜单的前列。

Yi 系列的成功，很大程度来自零一万物对「自研」的坚持。市场上不乏「套壳」或「微调开源模型」的创业公司，而零一万物选择从预训练开始搭建自己的技术栈，把数据、算力、算法都握在自己手里。Yi-34B 在英文与中文评测上的均衡表现，让它在海外开源社区也获得了认可，成为中国模型出海的代表之一。

零一万物的故事，也是「大模型六小龙」格局的注脚。和月之暗面、智谱、MiniMax、阶跃星辰等公司一样，零一万物赶上了中国大模型创业的黄金窗口，用明星创始人撬动资本与人才，再靠产品与模型证明自己。Yi 系列之后，公司又推出 Yi-Lightning 等版本，并逐步把重心转向企业级服务。

当然，明星创始人的公司也有明星公司的压力。资本期望高、竞争节奏快，零一万物在商业化路径上同样经历了摸索与调整。但无论如何，Yi-34B 留下的技术成就是真实的——它证明了在算力受限的创业环境下，中国团队依然能训练出进入全球第一梯队的开源模型。

回看零一万物的起点，它最有价值的不是某个参数数字，而是一种示范效应：当顶级投资人愿意下场做最重的自研工作，说明这个行业的想象空间足够大。李开复用 Yi 系列完成了一次身份的转换——从「投资人」到「创业者」，而 Yi-34B 就是这份转换最直接的证据。

In November 2023, 01.AI released the Yi model series. The company carried a halo from the day it was announced—founder Kai-Fu Lee, former president of Google China and founder of Sinovation Ventures, is among the most recognizable names in Chinese tech. When such a figure enters the model race, expectations run higher than for ordinary startups from the start. Yi-34B did not disappoint: with a long context window and solid bilingual ability, it reached the top of open-model leaderboards.

Yi's success owed much to 01.AI's insistence on self-research. The market was full of startups that "wrapped" or finetuned existing open models; 01.AI chose to build its own stack from pretraining, keeping data, compute, and algorithms in its own hands. Yi-34B's balanced English and Chinese results earned recognition in the overseas open-source community, making it a representative of Chinese models going global.

01.AI's story is also a footnote to the "six little dragons" landscape. Alongside Moonshot, Zhipu, MiniMax, and StepFun, 01.AI rode the golden window of Chinese model entrepreneurship, using a star founder to leverage capital and talent, then proving itself through products and models. After Yi, the company released versions like Yi-Lightning and gradually shifted toward enterprise services.

Of course, a star founder's company carries star-level pressure. Expectations from capital were high and competition fast; 01.AI also went through exploration and adjustment on the path to commercialization. But the technical achievement of Yi-34B is real—it proved that even under compute constraints in a startup environment, Chinese teams can train open models that enter the global first tier.

Looking back at 01.AI's start, its most valuable legacy is not a parameter number but a demonstration effect: when a top investor is willing to take on the heaviest self-research work, it says the industry's imagination is large enough. With the Yi series, Lee completed an identity shift from "investor" to "founder"—and Yi-34B is the most direct evidence of that transformation.
