EVENT DOSSIER
On August 13, 2026, the social platform X announced that it would make its ranking algorithm available to the public. This move allows users to use official tools to view their post rankings on the platform and determine whether there are cases of ‘shadow bans’ (i.e., content that has not been made public but has been derated by the system). This open-source initiative aims to increase transparency on the platform, enabling users to better understand the visibility status of their content.
X ranking algorithm source code 开源推荐算法代码并增加透明度工具
X 于周四宣布开源其"For You"时间线及核心排名引擎代码，并新增工具让用户查看账户或帖子是否受排名系统影响。公司将在 GitHub 上以 Apache v2 协议发布约 10 至 15 倍于此前规模的源代码，包含模型配置、过滤参数及权重信号细节。用户可通过应用设置中的"Under the Hood"页面下载 JSON 统计文件，查看近一个月应用的标签；非技术用户可借助 LLM 解读数据。该透明度工具初期仅对至少一年龄的测试账户开放，随后将全面推广。X 产品副总裁 Keith Coleman 表示，外部研究人员已能利用开源代码训练并运行 Phoenix 评分系统，开发者还可提交拉取请求改进算法，但使用 Grok 预测违规的规则系统除外。
