On 21 November 2021, Anthropic announced that it had made significant strides in improving the safety of Claude 2.1 by implementing a 200,000-token context window.

Anthropic is an American research and development company that focuses on the safe and beneficial development of artificial general intelligence (AGI). Founded in 2015 by former OpenAI researchers Dario and Daniela Amodei, Anthropic aims to create AI that is aligned with human values and that can benefit society.

Claude is a large language model (LLM) developed by Anthropic. LLMs are a type of artificial intelligence (AI) trained on a massive amount of text data. This training allows them to generate human-like text, translate languages, write different kinds of creative content, and answer your questions in an informative way. Claude is specifically designed to be safe, helpful, and honest.

According to Anthropic’s announcement, this extensive context window allows Claude 2.1 to access and process a vast amount of information when generating text, enabling it to produce more accurate and coherent responses. This enhanced context awareness also reduces the likelihood of Claude 2.1 producing factually incorrect or misleading outputs, a phenomenon known as hallucination.

To further enhance safety, Anthropic has implemented a range of techniques that have resulted in a 2x decrease in Claude 2.1’s hallucination rate. These techniques include improved training methods, fine-tuning on datasets specifically designed to detect hallucination, and the development of novel algorithms that can identify and flag potentially harmful outputs.

By combining the 200K context window with these advanced hallucination detection techniques, Anthropic has made remarkable progress in ensuring the safety of Claude 2.1, making it a more reliable and trustworthy tool for a wide range of applications.

Recognizing the potential of Claude 2.1 to benefit a broader audience, Anthropic has introduced an API tool that allows developers to integrate Claude 2.1’s capabilities into their own applications. This API provides a seamless way for developers to leverage Claude 2.1’s powerful text generation, summarization, and question-answering capabilities, enhancing the functionality and user experience of their applications.

The API tool offers several advantages for developers:

  • Ease of Integration: The API is designed to be easy to integrate into existing applications, allowing developers to quickly incorporate Claude 2.1’s capabilities into their code.
  • Customizable Parameters: Developers can fine-tune the behavior of Claude 2.1 by adjusting various parameters, enabling them to tailor the model’s outputs to their specific needs.
  • Scalable Performance: The API supports a high volume of requests, ensuring that Claude 2.1 can handle the demands of large-scale applications.

Anthropic has introduced system prompts, a new feature in Claude 2.1 that allows users to provide custom instructions to the model in order to improve performance. System prompts enable users to guide Claude’s outputs by specifying desired personalities, roles, or response structures, enhancing the model’s versatility and adaptability to user needs.

Claude 2.1 is now available through Anthropic’s API and powers the company’s chat interface at claude.ai for both free and Pro tiers. Pro users now have access to the 200K token context window, which allows them to process larger files and generate more comprehensive and contextually aware responses.
