Amazon announced that it will invest $4 billion in Anthropic, an artificial intelligence company based in San Francisco, which reflects the fierce competition between Amazon and Microsoft in the field of artificial intelligence. This is the latest huge investment in this field as part of the fierce competition between major companies around the world to exploit the potential of artificial intelligence. Amazon said earlier that it would use artificial intelligence to support the Alexa voice assistance service, and to be able to dialogue with users. Anthropic has Cloud, which is its competitor to GBT Chat.
