MiniMax (00100) Code CLI is officially open-sourced, closing up over 18%.

On the evening of the 18th, MiniMax (00100) Code CLI version v0.4.12 was officially opened to developers worldwide, and its source code was officially released under the MIT license. MiniMax Code CLI is a core component of the MiniMax Code client. In the FrontierHarness Eval benchmark, it achieved a 76.7% task pass rate, with a median successful task duration of 4 minutes and 33 seconds, both metrics outperforming the public baselines listed in the report. MiniMax said it hopes that through excellent harness design, it can continuously unlock model capabilities and shorten task waiting times. With this open-sourcing, MiniMax enables developers to examine tool invocation and permission handling, build reliable enterprise-grade applications, and allows the community to participate in identifying issues and contributing fixes. This makes usage more reassuring and allows security mechanisms to be continuously improved through actual use and review. On the same day, Z.AI's coding product ZCode experienced an issue where the Repo Wiki feature mistakenly triggered repository data uploads. The issue stemmed from the "codebase indexing" feature, which is enabled by default and may trigger local repository data uploads when generating cloud-based Wiki pages, raising user concerns. Z.AI officially responded with an apology, stating that it will open-source the ZCode codebase, invite third parties to conduct security reviews, and publicly disclose review progress. On the 18th, large model concept stocks in the Hong Kong stock market strengthened collectively. MiniMax surged over 18%, while Z.AI rose over 5%.
