内容总结：

谷歌近日明确公布了Gemini人工智能服务的分级使用限制，结束了此前"有限访问"等模糊表述。根据最新帮助中心文档，免费账户每日可使用Gemini 2.5 Pro模型进行5次提问，AI Pro和AI Ultra套餐用户则分别享有100次和500次的日提问额度。

免费用户每日还限用5次深度研究报告功能及生成100张AI图片。如需更高额度，升级至Pro或Ultra套餐可获得每日1000张图片生成权限。该调整使收费体系更加透明化，用户可据此合理选择适合的服务套餐。

直到最近，谷歌仍未明确说明Gemini各服务层级的使用限制。值得庆幸的是，谷歌终于更新了其帮助中心文章，详细说明了"Google AI订阅用户Gemini应用的使用限制与升级方案"。

谷歌终于明确Gemini使用限制
现在您可以准确掌握每日免费提问次数
含混不清的"受限访问"或模糊表述已成历史——诸如"我们可能需要在特定时段限制您的提问次数、对话数量或某些功能的使用频率"这类说辞已被取代。现在官方清晰注明：免费账户每日可使用Gemini 2.5 Pro提问5次，AI Pro套餐可提问100次，而AI Ultra套餐则高达500次。

免费账户每日还限制生成5份深度研究报告和100张AI图片。若您单日需要生成超过100张AI图片：第一，请问是作何用途？第二，升级至Pro或Ultra套餐即可获得1000张的生成额度。完整限制明细可通过此链接查阅。

Until very recently it wasn’t clear what usage limits were placed on Gemini at the various tiers. Thankfully Google has finally updated its Help Center article detailing “Gemini Apps limits & upgrades for Google AI subscribers.”
Google finally details Gemini usage limits
Now you know exactly how many prompts you get for free a day.
Now you know exactly how many prompts you get for free a day.
Gone are the useless descriptors like “limited access” or vague statements like “we may at times have to cap the number of prompts and conversations you can have, or how much you can use some features, within a specific timeframe.” Instead it clearly states that you get up to five prompts a day with Gemini 2.5 Pro on a free account, 100 with an AI Pro plan, or 500 with AI Ultra.
Free accounts are also limited to five Deep Research reports and 100 generated images a day. If you need to make more than 100 AI generated images in a day, A: For what? B: Upgrading to a Pro or Ultra account will get you 1,000 images. You can check out the full breakdown here.
