Frequently Asked Questions
Is Claude 3 Opus worth the Pro subscription?

How does Claude 3 compare to ChatGPT 4.5?
+Claude excels at accuracy, long document analysis, and ethical considerations, while ChatGPT leads in creativity, coding, and general versatility. Claude's 200K token context dwarfs ChatGPT's 128K, making it better for lengthy materials.
Can Claude 3 access the internet?
