Musk’s Latest AI Twist: The Company He Criticised Is Now Using His Computing Power

In a major development in the artificial intelligence industry, Elon Musk’s SpaceXAI has agreed to provide computing power to Anthropic, the company behind the Claude chatbot, despite months of public criticism between the two sides.

The partnership marks a sharp shift in relations between Musk and Anthropic. Over the past year, Musk repeatedly criticised Claude and the company on X, formerly Twitter, calling the chatbot “misanthropic”, “evil”, and “a threat to Western civilisation”.

Anthropic is now set to use the full capacity of Colossus 1, the Tennessee-based supercomputer operated by SpaceXAI. The facility reportedly runs on more than 220,000 NVIDIA GPUs, specialised chips used to train and run advanced AI models.

A GPU, or Graphics Processing

Unit, can process thousands of calculations simultaneously, making it essential for AI systems that require massive computing power.

The agreement comes at a time when competition in the AI sector is intensifying. Anthropic, despite being valued at nearly $400 billion and backed by Google and Amazon, has reportedly faced infrastructure constraints as demand for its AI tools continued to grow.

According to reports, the company needed significantly larger computing capacity to compete with rivals such as OpenAI. SpaceXAI’s infrastructure was considered one of the few capable of delivering that scale within a short timeframe.

Musk also defended the partnership publicly. Posting on X, he wrote: “I spent a lot of time last week with senior members of the Anthropic team… No one set off my evil detector.”

However, the arrangement reportedly includes a condition known as the “Humanity Clause”. Under this provision, SpaceXAI can withdraw computing access if Claude is found to be “engaging in actions that harm humanity”.

The clause reflects Musk’s long-standing concerns over AI safety and bias, issues he has frequently raised in public discussions.

The deal also serves a business purpose for Musk. Reports suggest SpaceXAI has already moved Grok’s training operations to the more advanced Colossus 2 system. Leasing Colossus 1 to Anthropic allows the company to generate revenue instead of leaving the infrastructure underused.
