National Day AI Programming Benefits: DeepSeek Vouchers and Multiple Domestic Models Limited-Time Free

Overview

During the National Day holiday, multiple domestic AI vendors launched limited-time free or resource-gift activities, providing users with high-quality coding model experiences. These activities cover multiple scenarios ranging from code generation to long-context processing, aiming to lower the barrier for developers.

Key Tip: The following resources are all targeted at AI coding scenarios. Specific quotas and validity periods are subject to the latest announcements on each platform's official page. Developers are advised to bookmark this guide and claim resources as needed.

Mainstream Platforms' Limited-Time Benefits

DeepSeek Harness client launched a login-to-receive-6-yuan-voucher activity, valid for 7 days, suitable for short-term intensive development needs. Meanwhile, the Qoder platform's Qwen3.8-Flash model incurs no charges during the event period, and logging in daily allows users to additionally claim 100 general credits, valid for 30 days.

The free activity for Hunyuan Hy3 / Hy4 was just extended to October 31. On WorkBuddy, Hy3 can be used freely without credits; Hy4 new users who activate their account for the first time before October 10 can enjoy a daily free quota for 14 days. Notably, WorkBuddy grants 100 credits upon login, and the DeepSeek V4 Flash rate has increased, so it is recommended to prioritize using this model to save quotas.

AtomCode CodingPlan offers long-term claimable free coding benefits; simply log in to the client to obtain them. These benefits are calculated on a 5-hour rolling window, approximately equivalent to 200 calls, with models dynamically allocated, primarily based on GLM-5.3-Flash.

Long Text and Internal Test Resources

For developers needing long-context processing, OpenCode Space Rabbit partnered with Meituan LongCat2.5 to provide 1M context and multimodal support, with free input/output caching. The event ends on October 5 and supports adjustable APIs.

ZCode's GLM-5.3-Flash releases 100 million tokens daily; while they do not roll over, there is a daily limit of 100,000 copies on a first-come, first-served basis. Subscribed users can use it infinitely between 23:00 every night and 09:00 the next morning. The event runs until October 7. MiniMAX Code's newly launched M3.1-Flash-Preview allows users to claim double credits via daily sign-ins from September 28 to October 7, granting 800 to 2000 credits upon login.

Meituan Miaoshou's LongCat2.0 version supports 1M context and 128K output, but requires claiming daily internal test spots within the official client. ShuSheng DuanYan provides monthly plans in its "Online Usage - Research Models" section, allowing free redemption of DeepSeek-V4-Flash-0731. This supports adjustable APIs and can be claimed every month.
