Yesterday in an announcement blog post, AI company Anthropic unveiled Claude 4, its new generation of AI models consisting of Claude 4 Opus and Claude 4 Sonnet with a range of new abilities. Both Claude 4 models are hybrid models,

Claude 4 Sonnet is a leaner model, with improvements built on Anthropic's Claude 3.7 Sonnet model. The 3.7 model often had problems with overeagerness and sometimes did more than the person asked it to do, Amodei said. While it's a less resource-intensive model, it still performs well, he said.

Anthropic has unveiled Claude 4, the latest generation of its AI models. The company boasts that the new Claude Opus 4 and Claude Sonnet 4 models are at the top of the game for AI assistants with unmatched coding skills and the ability to function independently for long periods of time.
