Hey! Nathan from Lex here. (You’re getting this email because you signed up for Lex, a new kind of word processor with powerful AI editing tools.)

Good news:

Yesterday, Anthropic released a new family of models called “Claude 3” that are extremely impressive.

• Opus, the largest model, is the first LLM to beat OpenAI’s GPT-4 in a wide array of benchmarks, and has “near-human levels of comprehension and fluency.”
• We love these models because they offer a unique perspective and tone that work especially well for writing feedback.
• To see how powerful they are, try clicking “identify weak arguments” or “get feedback on your draft” in the Ask Lex chat window.

You can use Claude 3 models today with a Lex Pro subscription. To get started, just login at https://lex.page, create or open a document, click “settings” and select one of the Claude 3 models.

​
