Trae China SOLO Goes Free—But the Same Queue Issues Resurface

Trae announced that the China‑version SOLO mode would be free for all users before 2025‑12‑25 , but a subsequent “resource coordination” notice delayed the rollout, leaving many developers disappointed.

After upgrading the client, the author found the SOLO mode silently unlocked and confirmed with several developer friends that it was usable.

The model selection screen displayed the promised domestic large models—Doubao‑Seed‑Code, GLM‑4.7, MiniMax‑M2.1—each available at no cost.

To test the free service, the author set a challenge: build a 2026 New Year webpage where fireworks could be controlled by hand gestures. Based on prior evaluations claiming code ability comparable to GPT‑5, GLM‑4.7 was chosen and the prompt was submitted.

The response included a queue notice placing the request at position 201, echoing the experience of the earlier international release. Switching to Doubao‑Seed‑Code yielded a much faster, smooth code generation, but the preview rendered a black screen with no fireworks, no gesture control, and no camera permission request.

Repeating the same prompt on the Trae international version, which uses Google’s Gemini 3 Pro , produced the expected fireworks effect and allowed hand‑gesture toggling of text dispersion and aggregation.

The author concludes that the underlying model capability, rather than the IDE itself, drives the experience. If possible, the international version is recommended for better performance; the domestic free version works but may require extra debugging, reflecting the cost of a free service.
