大模型 及InternLM模型介绍 1.1 什么是大模型? 大模型通常指的是机器学习或人工智能领域中参数数量巨大、拥有庞大计算能力和参数规模的模型。 利用大量数据进行训练、拥有数十亿甚至数千亿个参数、模型在各种任务中展现出惊人的性能 1.2 优势 大模型能够捕捉和理解数据中更为复杂、抽象的特征和关系。通过大规模参数的学习,它们可以提高在各种任务上的泛化能力,并在未经过大量特定领域数据训练的情况下实现较好的表现。 1.3 挑战 巨大的计算资源需求、高昂的训练成本、大规模数据的依赖、模型的可解释性 1.4 InternLM:模型全链条开源 InternLM 是一个开源的轻量级训练框架,旨在支持大模型训练而无需大量的依赖。通过单一的代码库,它支持在拥有数千个 GPU 的大型集群上进行预训练,并在单个 GPU 上进行微调,同时实现了卓越的性能优化。基于 InternLM 训练框架,上海人工智能实验室已经发布了两个开源的预训练模型:InternLM-7B和InternLM-20B。 Lagent 是一个轻量级、开源的基于大语言模型的智能体(agent)框架,支持用户快速地将一个大语言模型转变为多种类型的智能体,并提供了一些典型工具为大语言模型赋能。通过 Lagent 框架可以更好的发挥 InternLM 的全部性能。浦语·灵笔是基于书生·浦语大语言模型研发的视觉-语言大模型,提供出色的图文理解和创作能力,结合了视觉和语言的先进技术,能够实现图像到文本、文本到图像的双向转换。
