SpaceXAI releases Grok 4.5, which Elon describes as an ‘Opus-class model’

SpaceXAI 发布 Grok 4.5，埃隆·马斯克称其为“Opus 级别模型”

SpaceXAI has released its latest model, Grok 4.5 — the first since the company went public several weeks ago. In a blog post published Wednesday, SpaceXAI characterized its new release as a workhorse that can tackle all of the typical tasks that the AI industry has sought to automate: coding and app-building, office and clerical work, research, writing, and other forms of routine knowledge work.

SpaceXAI 发布了其最新模型 Grok 4.5，这是该公司几周前上市以来的首个模型。在周三发布的一篇博文中，SpaceXAI 将其新产品描述为一款能够处理人工智能行业旨在自动化的所有典型任务的“主力军”：包括编程和应用开发、办公室与文书工作、研究、写作以及其他形式的日常知识工作。

Grok can supposedly do all this for less spend, too, as SpaceXAI says that its model has “twice greater token efficiency” than other leading models. If it carries through to real-world use cases, that efficiency would be a big advantage for SpaceXAI, since the cost of tokens has been a growing concern for AI consumers. The company released benchmark metrics Wednesday that appeared to show Grok’s competitiveness with other top models from SpaceXAI competitors, although just short of best-in-class.

据称，Grok 还能以更低的成本完成所有这些工作，因为 SpaceXAI 表示，其模型的“Token 效率是其他领先模型的两倍”。如果这一效率能在实际应用场景中得以体现，将成为 SpaceXAI 的一大优势，因为 Token 成本一直是人工智能用户日益关注的问题。该公司周三发布的基准测试指标显示，Grok 与 SpaceXAI 竞争对手的其他顶级模型相比具有竞争力，尽管距离同类最佳仍有微小差距。

In a post on his social media platform X (which is a subsidiary of SpaceXAI), founder Elon Musk compared the model to Opus, Anthropic’s LLM designed for intensive and complex tasks. “Based on strong positive feedback from customers in our beta test program, @SpaceXAI will make Grok 4.5 available to the public tomorrow. It is an Opus-class model, but faster, more token-efficient and lower cost,” wrote Musk in his post on X.

在其社交媒体平台 X（SpaceXAI 的子公司）上，创始人埃隆·马斯克将该模型与 Anthropic 专为处理密集型和复杂任务而设计的 LLM 模型 Opus 进行了比较。马斯克在 X 上写道：“基于我们内测项目中客户的强烈积极反馈，@SpaceXAI 将于明天向公众开放 Grok 4.5。它是一款 Opus 级别的模型，但速度更快、Token 效率更高且成本更低。”

Musk later added: “Our internal assessment is that Grok 4.5 is roughly comparable to Opus 4.7, but much faster. The combination of capability, faster speed and lower cost is what makes it competitive.”

马斯克随后补充道：“我们的内部评估认为，Grok 4.5 与 Opus 4.7 大致相当，但速度要快得多。能力、更快的速度和更低的成本相结合，正是它具备竞争力的原因。”

SpaceXAI says that its new model costs $2 per million input tokens and $6 per million output tokens. That’s quite competitive, if Grok’s capabilities match SpaceXAI’s rhetoric. Opus 4.7, by comparison, costs $5 per million input tokens and $25 per million output tokens. OpenAI has tiered costs for different model versions: Sol, its most expensive, costs $5 for 1 million input tokens and $30 for 1 million output tokens, while its least expensive, Luna, costs $1 for 1 million input and $6 for 1 million output tokens.

SpaceXAI 表示，其新模型的定价为每百万输入 Token 2 美元，每百万输出 Token 6 美元。如果 Grok 的能力确实如 SpaceXAI 所宣传的那样，那么这一价格非常有竞争力。相比之下，Opus 4.7 的价格为每百万输入 Token 5 美元，每百万输出 Token 25 美元。OpenAI 对不同版本的模型采取分级定价：其最昂贵的模型 Sol 每百万输入 Token 收费 5 美元，每百万输出 Token 收费 30 美元；而其最便宜的模型 Luna 每百万输入 Token 收费 1 美元，每百万输出 Token 收费 6 美元。

It’s a big week for AI model releases. OpenAI is planning to release GPT 5.6, its latest, most powerful model, on Thursday. The release of that model had previously been limited by the Trump administration, due to concerns about its security implications. OpenAI has called it its “strongest model yet.”

对于人工智能模型发布而言，这是一个重要的星期。OpenAI 计划在周四发布其最新、最强大的模型 GPT 5.6。该模型的发布此前曾因安全隐患受到特朗普政府的限制。OpenAI 称其为“迄今为止最强大的模型”。
