提问 HN：AI 驱动的应用程序，请求限制与令牌限制哪个更重要？
2 分•作者: JeduDev•2 天前
目前，我正在开发一款用于管理文档、数据库和白板的 Web 应用程序，这是一款旨在对标 Notion 的典型应用。<p>然而，目前我面临着一个难题，即如何制定一个包含 AI 使用限制的计划，因为我的想法是让它更具自主性：例如，能够编辑和查询整个工作区中的上下文，并将其移动到文档中，或者在白板上绘制一些东西等等。但同时，我感觉 AI 的使用量很容易失控。我计划使用 DeepSeek 进行 AI 聊天，但使用 Gemini 3 Flash 进行自主操作和编辑，因为它更智能。最近，我看到许多核心 AI 应用已经将其定价模式从按请求计费转变为固定使用限制，但我不太确定这样做是否会被人诟病，是否会降低用户体验，甚至可能让人觉得没有物有所值。因此，我想听听大家对我的决策有什么看法。

Currently, I’m working on a web app for managing documents, databases, and whiteboards—the typical app that aims to be like Notion.<p>However, right now I’m facing the dilemma of creating a plan with AI usage limits, since the idea is to make it more agentic: able to edit and query context across an entire workspace and move it into a document, for example, maybe draw something on a whiteboard, etc. Still, I have the feeling that consumption could easily get out of hand. I plan to use DeepSeek for AI chat, but use Gemini 3 Flash for agentic usage and editing because it’s more intelligent. Lately, I’ve seen how many core AI apps have shifted their pricing models from per-request pricing to a fixed usage limit, but I’m unsure whether that’s frowned upon, creates a less pleasant user experience, or maybe even gives the feeling that you’re not getting what you paid for. So I’d like to hear some opinions on what decision I should make.
