How Does Claude 2 Work?

How Does Claude 2 Work?

Claude 2 utilizes advanced natural language processing techniques like transformers and reinforcement learning. Here’s a quick overview of how it works:

  • It takes in the user’s text input and processes it to understand the context and intent.
  • This input is fed into Claude’s proprietary AI model called PAL (Perceiver, Adapter and Latent-Optimizer).
  • PAL model is pre-trained on massive datasets and fine-tuned with human feedback for safety.
  • It generates a contextual response through multi-step inference and reasoning.
  • The response is checked against safety protocols to ensure it is helpful, harmless and honest.
  • Finally, Claude’s response is sent back to the user through text or speech.

So in a nutshell, Claude leverages large-scale AI while combining it with robust safety measures to have natural conversations.
