Updated: Jul 19, 2023

Claude 2 is a new model of AI chatbot developed by Anthropic, an AI startup founded by former OpenAI executives. According to the company, Claude 2 has improved performance, longer responses, and can be accessed via API as well as a new public-facing beta website, claude.ai.


Claude 2 is designed to be easy to converse with, clearly explain its thinking, and is less likely to produce harmful outputs. It has a longer memory and improved reasoning compared to previous models on coding, math, and reasoning. Claude 2 is capable of handling large contexts up to 100,000 tokens, roughly equivalent to 75,000 words, in a single digest.

Claude 2 is available for businesses via API for the same price as Claude 1.3, and anyone in the US and UK can start using the beta chat experience on claude.ai. Anthropic also offers a faster, less costly derivative of Claude called Claude Instant.


Claude 2 has been characterized as an AI powerhouse capable of advanced computational skills, such as scoring a 71.2% on the Codex HumanEval Python coding test and an 88.0% on GSM8k grade-school math problems. It has also been reported that Claude 2 is "2x better" at giving "harmless" responses compared to Claude 1.3 on an internal evaluation, although it is not clear what that metric means.
