Seek .(US:SKLTY) Hu Xiu·2025-08-26 07:25Group 1 - The latest version of DeepSeek (V3.1) has been found to insert unexpected tokens like "极/極/extreme" in various coding scenarios, affecting the coding process significantly [1][3][4] - This issue is not limited to third-party deployments; it also occurs in the official full precision version, indicating a broader problem within the system [3][5][18] - Previous bugs in DeepSeek included language mixing in writing tasks and overfitting in coding tasks, suggesting a pattern of instability in the model [6][8] Group 2 - The insertion of the token "极" can disrupt the syntax tree or cause the agent process to freeze, posing significant challenges for teams relying on automated coding or testing pipelines [8][20] - Other AI models, such as Gemini, have also faced stability issues, including a self-referential loop in coding scenarios, highlighting a common problem across AI systems [10][15] - The underlying cause of these issues may relate to the model's mechanical and probabilistic nature, which can lead to unexpected outputs when decoding processes are slightly disturbed [21][32]
