AI startup Anthropic is discussing a new $2 billion funding round with potential investors, including Alphabet Inc's Google, following Amazon's recent commitment to invest up to $4 billion in the company. The company aims to achieve a post-funding valuation of $20 billion - $30 billion, a significant increase from its $4 billion valuation in March. Anthropic is known for its generative AI models and plans to develop a more advanced model, Claude Next, requiring substantial capital due to its resource-intensive nature.
