Sept 7 (Reuters) - AI research lab Imbue has raised $200 million in a Series B funding round, which included participation from Astera Institute and Nvidia (NVDA.O), at a valuation of over $1 billion, the company said in a blog post on Thursday. Companies across the world, from banks to big tech, have doubled down on investments in artificial intelligence (AI) after ChatGPT, a generative AI chatbot by Microsoft-backed MSFT.O OpenAI took the world by storm in late 2022. "The latest funding will accelerate our development of AI systems that can reason and code," the company said.
