国庆假期过半，各家 AI 基本没再上新大活动。本期把假期里陆续冒出来的几条值得记的变化和低门槛入口补一补：阶跃 Step Plan 悄悄关了新领通道、上海青浦开了算力券申报、DeepSeek 桌面端上线顺手送 6 元赠金。顺手也把临期倒计时再理一遍，该薅的趁早。
1. 阶跃 Step Plan 悄悄关闭新领通道（官方变动）：原本"登录 15 天 + 首调 15 天 + 每邀 1 友 15 天（最多 3 人）= 最高 75 天"的免费体验，官方页面已挂出通知，将关闭新增免费体验领取通道。已领用户的剩余权益不受影响（以账户为准），但新用户现在按旧教程拉满 75 天已经行不通。已无法新领，老用户去 Step Plan 官方页确认自己账户剩余天数即可。
2. 上海青浦区算力券补贴申报通道开启（区域政策）：租用非关联方智能算力做研发的单位，按 9 月实际算力租用费用的 30% 申领补贴，单家年度封顶 1500 万元；另有"免申即享"通道（用国家区块链网络上海枢纽或列入上海高质量数据集名单），区块链最高奖 10 万、高质量数据集奖 5 万。登录"一网通办"→"随申兑·惠企政策精准服务专窗"提交电子材料，受理 2026 年 9 月 1 日–9 月 30 日的算力租用费用，申报窗口 10 月 1 日 9:00 – 10 月 23 日 17:00。
3. DeepSeek 桌面端（Harness）上线，登录送 6 元赠金（新增）：符合条件的 DeepSeek 用户登录 Harness 桌面端（v0.2 预览版），可限时领取 6 元体验赠金，无需充值；按 DeepSeek V4.1 Flash 非高峰价估算约可覆盖 1.2 亿缓存命中输入 Token。从官网下载 macOS/Windows 桌面端，用 DeepSeek 账号登录即可，赠金到账后 7 天有效，数量有限先到先得。
4. 四川天绛白泽 9.9 元"企业 token 尝鲜包"：企业付 9.9 元，得等效 9000 元的 GLM-5.3 大模型 5 亿 Token API 调用额度（输入输出合并计扣），自开通起 30 天有效；限量 100 份、每企业限购 1 次。需官网企业注册 + 法定代表人实名认证，在线签协议并对公转账 9.9 元后开通 API Key。
5. 火山引擎 Agent Plan 9.9 元/月：买"方舟 Agent Plan"套餐含 20,000 Agent 燃料值，集成 Doubao/GLM/DeepSeek/Kimi/MiniMax 主流编程模型 + 多模态，可接 TRAE、Claude Code、Codex CLI 等。属低成本编程套餐，1 个月有效期，注意订阅制别让它自动续。
临期倒计时（国庆里陆续到关）：智谱 ZCode 数据事件补偿（9/28–10/7 每天发"1 亿 Token×10 万份"）、智谱双节夜间畅用（GLM-5.3-Flash 23:00–09:00）延到 10/7、MiniMax M3.1-Flash-Preview 签到双倍积分（9/28–10/7）、DeepSeek Harness 6 元赠金（约 10/6）、混元 Hy4 preview 新规窗口到 10/10、珠海算力券到 10/14、上海青浦算力券到 10/23、阿里 Qoder×Qwen3.8-Flash 10/1 起继续免费、豆包工作 30 天订阅续杯到 10/17、富国基金送智谱清言 VIP 月卡、WorkBuddy 国内版 Hy3 限免 + Hy4 preview 夜间限免及湖北算力券均到 10/31。
长期稳定白嫖入口：腾讯元器（新用户直送 1 亿 Token，个人 10 万次/月免费 API）、腾讯云 TokenHub（混元新人包到 12/31）、阿里云百炼/百度千帆（新用户每模型送 100 万 Tokens）、火山方舟（实名后每天 200 万 Tokens）、月之暗面 Kimi（新用户约 800 万 Tokens）、DeepSeek（新开发者送 500 万 Tokens，网页/App 对话长期免费）、商汤 SenseNova Token Plan（长期免费公测）、讯飞星火 Spark Lite（永久免费 API）、阶跃 Step Plan（已关闭新领通道，已领权益以账户为准）、硅基流动（小模型免费已取消，现仅 embedding/语音/OCR/翻译/Kolors 免费）。
避坑提醒：市面上没有通用「AI 兑换码/CDKey」，卖新人激活码的基本是钓鱼；地方词元券/算力券都是区域或企业定向，认准官方平台入口，二手兜售一律当诈骗；「DeepSeek 永久会员 79.9 元」是谣言；智谱 ZCode 善后已落地，仍建议自查本地仓库有无敏感密钥。

The National Day holiday is halfway through and the various AI vendors have basically not launched any big new campaigns. This issue covers a few worthwhile changes and low-threshold entry points that emerged during the holiday: StepFun quietly closed new redemption channels, Shanghai Qingpu opened compute voucher applications, and DeepSeek's desktop edition launched with a 6 yuan bonus. I've also tidied up the expiring countdowns again — grab what you can while you can.
1. StepFun Step Plan quietly closes new redemption channels (official change): the free trial that was 'log in 15 days + first 15 days + 15 days per friend invited (max 3 people) = up to 75 days' now has a notice on the official page saying the channel for new free trial redemption will close. Existing users' remaining benefits are unaffected (subject to the account), but new users can no longer max out 75 days following the old guide. Redemptions are already closed, and old users should go to Step P
2. Shanghai Qingpu district compute voucher subsidy application channel opens (regional policy): units renting non-affiliated intelligent compute for R&D can apply for a subsidy of 30% of actual September compute rental costs, capped at 15 million yuan per company per year; there is also a 'apply-and-enjoy' channel (using the national blockchain network Shanghai hub or being on Shanghai's high-quality dataset list), with blockchain awards up to 100,000 yuan and high-quality dataset awards of 50,000 yuan. Log into 'Yiwang Tongban' → 'Suishen Dui · Enterprise Policy Precision Service Window' and submit electronic materials
3. DeepSeek desktop edition (Harness) launches with a 6 yuan login bonus (new): eligible DeepSeek users who log into the Harness desktop edition (v0.2 preview) can claim a limited-time 6 yuan experience bonus with no top-up required; estimated against DeepSeek V4.1 Flash off-peak pricing, this covers roughly 120 million cache-hit input tokens. Download the macOS/Windows desktop
4. Sichuan Tianjiang Baize 9.9 yuan 'enterprise token trial pack': pay 9.9 yuan and get API call quota equivalent to 9,000 yuan of GLM-5.3 large model, 500 million tokens (input and output counted together), valid for 30 days from activation; limited to 100 sets, one per company. Requires enterprise registration on the official site plus real-name authentication of the legal representative, then signing the agreement online and transferring 9.9 yuan via corporate payment before the API Key is enabled.
5. Volcano Engine Agent Plan 9.9 yuan/month: the 'Ark Agent Plan' package includes 20,000 Agent fuel points, integrating mainstream coding models Doubao/GLM/DeepSeek/Kimi/MiniMax plus multimodal, and connects to TRAE, Claude Code, Codex CLI and others. It is a low-cost coding package valid for 1 month — note it is a subscription, so don't let it auto-renew.
Expiring countdowns (closing through the holiday): Zhipu's ZCode data event compensation (9/28–10/7, giving out '100 million tokens × 100,000 copies' daily), Zhipu's double-festival night usage (GLM-5.3-Flash 23:00–09:00) extended to 10/7, MiniMax M3.1-Flash-Preview check-in double points (9/28–10/7), DeepSeek Harness 6 yuan bonus (
Long-term stable free entry points: Tencent Yuanqi (new users get 100 million tokens direct, 100,000 free API calls/month for individuals), Tencent Cloud TokenHub (Hunyuan newcomer package until 12/31), Alibaba Cloud Bailian/Baidu Qianfan (new users get 1 million tokens per model), Volcano Ark (2 million tokens daily after real-name verification), Moonshot Kimi (around 8 million tokens for new users), DeepSeek (new developer
Pitfall reminders: there is no universal 'AI redemption code / CDKey' on the market — sellers of new-user activation codes are basically phishing. Local token vouchers and compute vouchers are all region- or enterprise-targeted, so use official platform entry points and treat any second-hand resale as fraud. 'DeepSeek permanent membership 79.9 yuan' is a rumour. Zhipu's ZCode aftermath is settled, but you should still check your local repositories for sensitive keys.
