Claude 2 is a new AI model released by Anthropic that improves upon Claude 1.3 with better performance, longer responses, and larger input and output capabilities. Claude 2 scored higher on various tests and evaluations compared to Claude 1.3, indicating improved coding, math, and reasoning skills. Anthropic has worked to make Claude 2 safer and less likely to produce harmful outputs through various techniques. Claude 2 powers Anthropic's new chat experience and API that businesses like Jasper and Sourcegraph are using to enhance their own products, citing Claude 2's larger context window, improved reasoning, and up-to-date knowledge. Anthropic welcomes feedback as they work to responsibly deploy Claude 2 more broadly.

We are pleased to announce Claude 2, our newest model, which can be accessed via API as well as a new public-facing beta website at claude.ai.

Will be interesting to see how it compares to chatgpt4.

We are pleased to announce Claude 2, our new model. Claude 2 has improved performance, longer responses, and can be accessed via API as well as a new public-facing beta website, claude.ai. We have heard from our users that Claude is easy to converse with, clearly explains its thinking, is less likely to produce harmful outputs, and has a longer memory. We have made improvements from our previous models on coding, math, and reasoning. For example, our latest model scored 76.5% on the multiple choice section of the Bar exam, up from 73.0% with Claude 1.3. When compared to college students applying to graduate school, Claude 2 scores above the 90th percentile on the GRE reading and writing exams, and similarly to the median applicant on quantitative reasoning.
