"趁你病要你命"，趁着国内市场输入法赛道的领军者搜狗输入法陷入"病毒"争议，字节跳动旗下的AI助 手豆包似乎也要做输入法了。近日有爆料称，豆包输入法iOS版已经开始内测，并主打豆包同款的AI语 音识别，以及越用越准的智能联想功能。 事实上，"AI+输入法"是国内互联网厂商在探索AI大模型技术落地时，就曾经进行过的尝试。早在2023 年秋季，百度输入法方面就宣布全面升级，打造行业首个"基于大模型的输入法原生应用"，并从"输入 工具"全面转型为"AI创作工具"，旨在成为用户的全场景"AI创作助手"。 到了2024年夏季，腾讯方面宣布微信输入法迎来升级、上线基于混元大模型打造的"一键AI问答"功能， 为用户提供智能交互体验。用户只需要在微信聊天框中输入内容后添加一个"="符号，就能迅速获得AI 的智能回答。随后搜狗输入法也宣布迎来AI功能上新，带来AI帮写、AI对话、快捷问答、AI宠物、AI 自拍表情等多种功能。 彼时互联网大厂看中输入法，是因为这一时期的AI大模型还是以文生文、文生图为主，而输入法则是 关联这两种能力的最佳载体之一，通过输入法就可以让用户得以习惯AIGC，进而润物细无声般完成市 场教育。只可惜后来 ...
