Anthropic on Monday announced Claude Opus 4.5, its latest artificial intelligence model that the startup says excels at coding, using computers and assisting users with complex enterprise tasks.
Claude Opus 4.5 marks Anthropic's third major model launch in two months, and it serves as the latest example of the nonstop pace of development within the AI industry. The startup unveiled its Claude Sonnet 4.5 model in late September, followed by its Claude Haiku 4.5 model in October.
"The amount that we're releasing to the market and the feedback loops that we're generating from it just make me so unbelievably excited," Scott White, product leader for Claude.ai at Anthropic, told CNBC in an interview.
Anthropic is an AI startup that was founded by a group of former OpenAI researchers and executives in 2021. Microsoft and Nvidia announced multi-billion-dollar investments in Anthropic last week, boosting the AI lab's valuation to about $350 billion.
The company is best known for developing a family of AI models called Claude. It assigns new numbers to the models as they advance across generations, but the largest model in the family is typically called Opus, the midsized model is called Sonnet and the smallest model is Haiku.
The last Opus model, which Anthropic released in August, was called Claude Opus 4.1.
