按厂家浏览模型Browse models by provider

Provider、模型和免费入口是三件不同的事Provider, model and free access are three different layers

Provider 页面回答“这家厂商当前公开了哪些模型”；模型页回答“同一个模型在哪些接入路径出现”；Offer 详情页才回答“当前有哪些免费、试用、优惠或低成本入口”。把三层分开，可以避免把一个模型存在误判成它一定免费。Provider pages answer which models a vendor currently exposes; model pages show where the same model appears; offer pages explain the current free, trial, promotional or low-cost access paths. Keeping these layers separate prevents model availability from being mistaken for free access.

• 先看最近同步Check last sync first：模型目录可能变化，最近同步时间可以帮助判断页面是否仍代表当前状态。Provider catalogues change, so the last-sync date helps you judge how current the page is.
• 再看来源级别Then check source level：“厂商来源”来自公开模型目录；“操作指南”表示我们只有接入/使用证据，不把它伪装成完整模型目录。“Provider source” comes from a published model catalogue; “operation guide” means we have setup/use evidence but do not pretend it is a complete catalogue.
• 最后找免费入口Finally find a free path：进入厂商详情后再看本站 Offer 记录，核对免费机制、地区、额度、账号要求和最后核验时间。Open the provider detail and then the related FreeLLM offer records to verify the free mechanism, region, quota, account requirements and last-checked date.
