The article discusses Google’s recent partnership with AI startup Anthropic and the potential competition concerns raised by the UK’s Competition and Markets Authority (CMA). The CMA is investigating whether the deal could lead to a substantial lessening of competition in the artificial intelligence (AI) market. Anthropic is a San Francisco-based startup that develops AI systems, including a language model called Claude. The partnership involves Google taking a stake in Anthropic and gaining access to its AI technology. However, the CMA is concerned that the deal could reduce competition and innovation in the AI sector, particularly in the development of large language models. The investigation will assess whether the partnership could lead to higher prices, lower quality, or reduced choice for businesses and consumers in the UK. The CMA has invited third parties to provide comments and evidence to assist its investigation.
