Free if: Inside the official CodeBuddy / WorkBuddy clients, CN site: Hy3 runs at a 0.00x credit multiplier (limited-time free), Hy4 preview is free only 23:00-08:00 Beijing; other models deduct credits at the multiplier the client shows
To start: $0 · accountTencent Buddy AI personal account, CN site (workbuddy.cn / codebuddy.cn, WeChat or phone sign-in); 体验版 500 credits/month, no card. The pricing page lists CLI access as a paid-tier feature (体验版 shows -), yet the CLI answered on a 体验版 account on 2026-10-28 (限免 period)
Added hy3-codebuddy: Hy3 is 限时免费 all day inside the official CodeBuddy / WorkBuddy clients (CN site, one shared credit pool). Own check the same day: the CLI model table served the multiplier x0.00 and 5 one-shot runs (~120k tokens) took 0 credits. The official mini-program model table has labelled Hy3 限时免费 since its 2026-07-22 revision
Added hy4-preview-codebuddy as listed: only the night window 23:00-08:00 (Beijing) carries a free quota, so the window itself is untested here. Daytime read the same day: the CLI model table served Hy4 preview at x0.29 and the model answered. The official notice adds that Hy4 preview is a text-only model, so an image or video sub-task it hands over to another model is billed normally
Tencent notice of 2026-09-30 evening (carried by IT之家 2026-10-02): Hy3 free and Hy4 preview night free (23:00 to 08:00 next day) are both extended to 2026-10-31. Because participation was very high, the daily free quota is distributed per user and requests enter a queue when that day's capacity is busy (the page shows the reset time). Users who had never opened Hy4 preview had to start their first Hy4 preview chat before 2026-10-10 23:59 to get 14 days of daily free quota from that day → end date Oct 31
