Anthropic has achieved a remarkable feat with its Sonnet Large Language Model (LLM). The fact that users didn't notice the switch from Opus to Sonnet for two weeks highlights the impressive quality and seamless integration of this new model. This shows remarkable progress in Generative AI technology.
