SpaceX has completed its $60 billion acquisition of AI coding startup Cursor, granting the company access to the world's largest GPU fleet for lower-cost model development. The deal, which began with an April partnership and follows SpaceX's merger with xAI, has already produced Grok 4.5 and 4.6 focused on coding and real-world tasks.
The $60 billion transaction, which the firms first revealed in June, reportedly supplies Cursor with access to "the largest fleet of GPUs in the world."
It was designed to "excel at coding, agentic tasks and knowledge work" and to deliver results "at far lower costs."

The Circuitry is a passion project I've always wanted to build, and I love the work behind it.
Running it costs real money. APIs, hosting, time. To keep improving the site and growing this into something useful for everyone, those costs have to be covered.
Any contribution is appreciated. If not, no pressure. Thanks for reading.
SpaceX has agreed to acquire Grain Management's nationwide 800 MHz spectrum portfolio, which it says will pave the way for Starlink Mobile to become a major US mobile carrier. The deal needs FCC approval, and financial terms were not disclosed.
Anthropic has launched the Anthropic Cyber Mission to support defenders of critical infrastructure and open-source software with models, engineers, and tools. The initiative starts with the Critical Infrastructure Defense Program and free OSS Scanner amid ongoing challenges in verifying and fixing vulnerabilities.
Anthropic released Claude Haiku 5.5, its cheapest and fastest small model, at $0.10 per million input tokens and $0.50 per million output tokens for prompts up to 100,000 tokens. Anthropic says it costs around 75% less to run than Haiku 4.5 on average and scores far higher on its benchmarks.
OpenAI released 722 mathematical manuscripts, grouped into 372 result families, produced by an unreleased internal model. The papers are on GitHub, with Lean formalizations for many but not all of them, and OpenAI warns some unformalized results could have issues.
Meta and Microsoft are cutting employee use of Anthropic’s Claude AI and directing staff toward their own coding tools, The Information reported. The changes reflect tighter internal AI budgets while customer access to Claude through Microsoft platforms continues to expand.
