MiniMax 新文本模型 M3.1-Flash-Preview 开启公测
MiniMax 宣布新文本模型 M3.1-Flash-Preview 正式公测，主打原生多模态与最高百万字符超长上下文，可用于代码 bug 修复、复杂函数开发及问题定位—实现—测试验证闭环。文章还提到此前匿名模型 Space Bunny 于 9 月 23 日上线，曾在 OpenRouter 和 OpenCode 日使用量登顶，但两者关联仅为开发者推测，官方未确认。
AI推荐理由 MiniMax 官方宣布新文本模型 M3.1-Flash-Preview 开启公测，给出原生多模态和百万字符超长上下文两项具体能力，并提及代码修复、函数开发与测试验证等用途；但正文未提供模型参数、评测数据或官方技术文档链接，'Space Bunny' 与 M3.1 的关联仅为开发者推测，文中'底层技术实力已得到全面验证'属无依据断言，需保留不确定性。

The iteration speed in the field of large-scale artificial intelligence models is continuously breaking industry records. On September 28th, the leading domestic AI company MiniMax officially announced that its new text model M3.1-Flash-Preview has been launched and is now open for full public testing.
Regarding core technologies and functional features, this model has two highlights: first, it fully supports native multimodal capabilities, and second, it has an ultra-long context window of up to a million characters. In practical application scenarios, it not only efficiently completes code bug fixes and complex function development from scratch, but also deeply participates in the entire closed-loop process of problem identification, code implementation, and test verification, providing developers with highly reliable productivity support.
Notably, before this model was officially unveiled, some keen developers had already linked it to a previous anonymous model called "Space Bunny" (meaning "Space Rabbit" in Chinese) that was launched on September 23rd. According to publicly available data, this mysterious "Space Rabbit" performed impressively during the Mid-Autumn Festival holiday, once ranking first in daily usage volume on the model aggregation platform OpenRouter and the programming platform OpenCode, attracting widespread attention from technology enthusiasts. With the official unveiling of M3.1-Flash-Preview, its underlying technical strength has also been comprehensively validated.
