Claude 急了！模型降智，官方长文用 bug 搪塞？开发者怒怼“太晚了”：承认不达标为何不退钱？

Core Viewpoint - Anthropic has acknowledged a decline in the quality of its Claude model between August and early September, attributing the issues to three infrastructure bugs that affected user experience and response quality [4][8][9]. Group 1: Incident Overview - Users reported a degradation in Claude's performance starting in early August, with a significant increase in complaints by the end of the month [4][8]. - Anthropic identified three distinct bugs that contributed to the service degradation, emphasizing that these issues were not due to demand or server load changes [4][9]. - The company has committed to improving its infrastructure and monitoring processes to prevent similar issues in the future [22][25]. Group 2: Specific Bugs and Their Impact - The first bug involved routing errors that affected approximately 0.8% of requests initially, which escalated to 16% by the end of August due to a load balancing change [9][10]. - The second bug, related to output anomalies, occurred due to a misconfiguration on August 25, leading to incorrect token generation in responses [11][12]. - The third bug was a compilation error in the XLA:TPU system, which affected the token selection process and was linked to performance issues in specific model subsets [13][14]. Group 3: User Reactions and Trust Issues - Users expressed frustration over the ongoing performance issues, with some stating they would not renew their subscriptions unless significant improvements were made [24][29]. - Complaints highlighted that despite being paid users, they continued to experience service problems, leading to a loss of trust in the product [31][32]. - Anthropic's response to user feedback has been perceived as insufficient, with calls for more transparent communication and accountability regarding service quality [25][33].
