Anthropic, an AI company based in San Francisco, has launched Claude 2, the second generation of its natural language generation chatbot. Anthropic claims that Claude 2 is smarter than 90% of college students in the United States and Canada. The new chatbot performs better, provides longer responses, and has improved coding, math, and reasoning capabilities. Claude 2 can process up to 100 tokens of input or output, equivalent to 75,000 words, making it capable of handling complex questions and generating detailed reports.
Anthropic states that Claude 2 has achieved remarkable results in real-world tests. It scored 76.5% on the Bar exam’s multiple-choice section, surpassing the 73.0% achieved by Claude 1.3. It also achieved scores above the 90th percentile in the GRE reading and writing exams, outperforming college students applying to graduate school.
Using Claude 2 is straightforward, and the chatbot remembers the user’s preferred information presentation format. It responds quickly and can simplify lengthy answers into bullet points upon request. Claude 2 has also demonstrated improved coding skills, achieving a score of 71.2% on the Python coding test, Codex HumanEval, compared to its predecessor’s score of 56.0%. Additionally, it scored 88.0% on GSM8k, a set of grade-school math problems, an improvement from the previous score of 85.2%.
Anthropic has a roadmap of capability improvements planned for Claude 2. To test these capabilities, they have launched a public beta of Claude 2 in the U.S. and U.K. The chatbot employs new safety techniques developed by Anthropic, including reinforcement learning from human feedback (RLHF) and Constitutional AI. These techniques enhance self-correction abilities and allow Claude 2 to identify and reject inappropriate requests. Consequently, Claude 2 delivers harmless responses twice as effectively as its predecessor.
The focus on making chatbots safer to use aligns with the concerns of government bodies and regulators worldwide. The White House, the E.U., and the FTC have all expressed the need for regulations addressing the risks associated with generative AI models like chatbots and deepfakes. These regulations aim to tackle issues such as bias, privacy, misinformation, and fraudulent use of personal data. By emphasizing accuracy and safety, Anthropic’s Claude 2 sets a new standard for AI chatbots.
Since the release of ChatGPT, the popularity of generative language models has surged. Tech giants like Google, Meta, and Microsoft have launched their own massive language models, and smaller startups are joining the race by offering creative generative AI apps for writing, art, and coding. However, accuracy and the prevention of harmful content remain key concerns for policymakers. It is in this landscape that Claude 2 emerges as a promising contender, addressing safety measures while delivering impressive performance.
