Z.ai 证实 Ox Alpha 是其 GLM 系列新模型，将于周三开源权重
Surprise: Z.ai is the AI lab behind the mysterious Ox Alpha model
谜底揭晓：Ox Alpha 由智谱（Z.ai）打造，是其 GLM 系列最新迭代，此前匿名上线 OpenRouter 后已在多项基准测试中登顶。Z.ai 确认将于周三发布 Ox Alpha 权重，供开发者在其基础上构建。该模型被描述为面向编程、持续智能体工作与生产负载的推理模型，其发布加剧了中国高性价比模型对 OpenAI、Anthropic 等高价前沿模型的竞争威胁。
Over the weekend, the nerds were buzzing with speculation over which AI lab was behind Ox Alpha, the mysterious new open-weight AI model launched onto OpenRouter anonymously and already topping benchmarks and leaderboards against the best models.
As many had expected, Ox Alpha was spawned by GLM-maker Z.ai, according to Bloomberg. Z.ai confirmed that Ox Alpha is the newest iteration of its GLM series, which Hugging Face famously used recently to defend itself against an attack from OpenAI agents.
The company said it will release the weights for Ox Alpha on Wednesday, after which developers can build on top of it. The company describes Ox Alpha as “a reasoning model designed for coding, sustained agentic work, and production workloads. It is suited for long-horizon software engineering, complex reasoning, and workflows that combine text with visual context.”
The release of Ox Alpha adds to the burgeoning threat of cheap, capable models from China that could take real market share away from expensive frontier model companies like OpenAI and Anthropic.
Earlier this month, Z.ai released GLM-5.3, which rivals Anthropic’s Fable 5 on certain benchmarks.
