Meet Claude 2, the latest large language model AI to challenge OpenAI's ChatGPT
that to have a realistic chance of making powerful AI safe, they need to be developing powerful AI systems themselves in order to test the most powerful systems and potentially use them to make future systems more powerful. Claude 2 is perhaps the next step towards Claude-Next.
The second technique, which was developed by researchers at Anthropic and which differentiates Claude 2 from GPT-4 and many of its other competitors, is called constitutional AI. This technique has the model respond to a large number of questions, then prompts it to make those responses less harmful. Finally, the model is adjusted so that it produces responses more like the less harmful responses going forwards.
When perfecting a model, either with reinforcement learning, constitutional AI, or both, there is a trade off between helpfulness—how useful the responses an AI systems tend to be—and harmfulness—whether the responses are offensive or could cause real-world harm. Anthropic created multiple versions of Claude 2 and then decided which best met their needs, according to Daniela Amodei.Claude 2 performed better than Claude 1.
