护城河:记忆与编程
</div>
<div class="card-content">
<p><strong>记忆是 AI 无法逾越的护城河:</strong><br>一个经过长时间磨合、内化了特定任务模式与背景记忆的 Agent,其价值远高于通用的超级模型。拥有长期记忆的 Agent 能够持续积累经验。</p>
<div class="concept-box">
<strong>编程能力是 AGI 的终极形态:</strong><br>
代码是通用的语言。如果一个 Agent 能写代码,它就能调用任何 API,构建任何工具。未来的通用 Agent,本质上就是一个“Coding Agent”。
