SAN FRANCISCO, Aug 27 (Reuters) – Anthropic discussed buying artificial intelligence chip startup MatX for roughly $7 billion, seeking to accelerate efforts to develop custom hardware for its fast-growing AI business, ​two people briefed on the matter told Reuters.

The merger talks, which ‌a third person said have evolved into a discussion about a partnership, underscore the AI lab’s ambition to secure the resources and talent needed to build its own chips. The goal is to help Anthropic accelerate its in-house chip development.

Reuters is reporting on the discussions for the ‌first ​time but could not learn why the talks are ⁠no longer active. MatX, founded ⁠by former Google tensor processing unit (TPU) engineers, is now seeking to raise new capital at a valuation of about $4 billion, one of the people said, requesting anonymity to discuss private matters.

Anthropic declined to comment on deal talks with ​MatX. MatX did not respond to a request for comment.

The discussions with MatX also suggest Anthropic may be interested in producing a training chip, while other ⁠chip startups and rival OpenAI pursue processors that ⁠are better suited to generating responses from chatbots, a process ​known as inference. Anthropic could elect to produce an inference chip as well, the ​sources said.

In recent weeks, Anthropic held meetings with a range of ‌AI chip startups as the company seeks to hone its efforts to produce a specialized AI chip. It has not yet elected to make an acquisition. The meetings are an attempt by Anthropic’s engineers and executives to understand the current range ⁠of chip design approaches.

This week, Anthropic hired Google chip veteran Amir Salek as part of the company’s push into hardware. In June, the AI lab hired former OpenAI ⁠chip engineer Clive Chan who ‌worked on the OpenAI chip unveiled earlier this year.

The ⁠leading AI labs such as Anthropic and OpenAI have become ​increasingly focused ‌on custom chips, which can be tailored to their ​models and ⁠workloads. Through this, they hope to create significant performance and economic advantages.

At a conference this week OpenAI boasted that its first custom chip called Jalapeno outperformed a similar processor made by Nvidia. OpenAI executives noted that the chip was more energy efficient in performing inference calculations.
