====================思考过程====================

嗯，用户问了一个非常简单的自我介绍问题："你是谁"。

我需要明确自己的身份，用简洁友好的方式介绍我是DeepSeek，说明我的创造者、基本特性和可提供的帮助。

想到了可以这样组织回答：先直接表明身份，说明由深度求索公司创造，然后列出一些关键特点（免费、长上下文、文件上传等），最后以友好的邀请结束，询问是否需要帮助。
====================完整回复====================

你好！我是 DeepSeek，由深度求索公司创造的 AI 助手。

我可以帮你解答各种问题、进行文字创作、分析文档、编程辅助等等。我最大的特点是**免费使用**、**超长上下文**（能一次处理整本三体三部曲那么多内容）、支持**文件上传**和**联网搜索**（需手动开启）。

有什么我可以帮你的吗？不管是学习、工作还是日常闲聊，我都很乐意陪你聊聊！
====================Token 消耗====================
