Simon Mo说开源模型和闭源模型能力没差多少，关键看谁把模型落地做得更好，vLLM已经在50万GPU上跑了。
Simon Mo认为开源权重模型与闭源权重模型在能力上没有明显差距，差异主要在分发策略和进入市场方式。他提到vLLM目前运行在50万个GPU上，证明开源基础设施的规模。Mo指出关键不在于数据来源，而在于谁能构建更好的训练环境并做出更优的算法选择。他认为接下来一年开源模型实验室将专注于让模型适应真实世界，一年后两者差距将消失。

Inferact Co-founder Simon Mo on the trajectory of open and closed models: "What really differentiates open-weight models from closed-weight models, right? In the end, there's not much differentiation. It's more about the distribution strategy and go-to-market strategy... Capability-wise, I don't really see a big gap, not even today." "It's not about just source data. It's not about where to get the data from. Rather, it's who can build the best environment and who can make the most optimization and algorithmic choices to leverage all this learning from this environment." "So the next year is all gonna be about that. It's about how open-weight model labs are differentiating and really getting the model to meet the real world." "Project out in a year, there's not gonna be any difference." @simon_mo_ Your browser does not support the video tag. 🔗 View on Twitter a16z @a16z vLLM runs on half a million GPUs at any given moment.
