Nov 7 (Reuters) - Amazon.com ( AMZN ) is in talks for

its second multi-billion dollar investment in artificial

intelligence startup Anthropic, the Information reported on

Thursday, citing a person familiar with the matter.

The cloud services giant announced an investment of $4

billion in the OpenAI rival in September last year, saying its

customers would gain early access to Anthropic's technology.

Amazon ( AMZN ) has asked Anthropic, which uses Amazon's ( AMZN ) cloud

services to train its AI model, to use a large number of servers

powered by chips developed by the cloud computing major, the

report said.

It added that the AI startup prefers to use Amazon ( AMZN ) servers

powered by Nvidia ( NVDA )-designed AI chips.

Amazon ( AMZN ) and Anthropic declined to comment.

Anthropic, which was co-founded by former OpenAI executives

and siblings Dario and Daniela Amodei, last year said it had

secured a $500 million investment from Google-parent Alphabet

, which promised to invest another $1.5 billion over

time.
