SpaceXAI Will Reportedly Release a Major New AI Model This Week
Expert Analysis
SpaceXAI (formerly xAI) is reportedly launching a new frontier AI model as early as this week. This model is said to be the first joint production between SpaceXAI and Cursor, an AI startup that SpaceX is in the process of acquiring for $60 billion.
Last month, Elon Musk posted on X that his company's latest unreleased model, Grok 4.5, based on a 1.5T V9 foundation model with Cursor data, was being beta tested privately at SpaceX and Tesla, with performance comparable to an unspecified version of Claude Opus. According to The Information, the model is being internally compared to Claude Opus 4.8 and OpenAI's GPT 5.5.
- Key Takeaway: SpaceXAI (xAI) is launching a new AI model, Grok 4.5, co-developed with Cursor, aiming to compete with top-tier models like Claude Opus and GPT 5.5.

Claude and ChatGPT Are Getting Too Expensive, Even for Microsoft
Expert Analysis
Microsoft is reportedly finding the use of advanced AI models like Claude and ChatGPT to be too expensive, even for a company of its size. The cost of AI tokens, which measure computing work, is becoming so prohibitive that Microsoft is turning to its own models to save money.
According to Bloomberg, tens of thousands of AI prompts each week in Microsoft's Excel and Outlook software are now being completed using Microsoft's own MAI models. These programs previously relied more heavily on models from OpenAI and Anthropic.
Microsoft recently unveiled seven new in-house models, including MAI-Thinking-1, its first reasoning model. This model was built for "high efficiency and performance, but importantly, at a low-token cost," and in blind tests, it matched the coding abilities of Anthropic's popular Claude Opus 4.6. Microsoft AI CEO Mustafa Suleyman stated that their goal is to reduce and ultimately eliminate the significant costs paid to Anthropic.
- Key Takeaway: Microsoft is shifting from expensive third-party AI models like Claude and ChatGPT to its own in-house MAI models, including the cost-efficient MAI-Thinking-1, to reduce high token costs.
