Asking GPT-4 to describe itself

GPT-4, a product of OpenAI, is a large language model that is also a significant multimodal model. It is known for its proficiency in responding to both written and image-based prompts, with areas of expertise including:

  • Answering questions
  • Telling stories
  • Solving complex problems
  • Composing intricate essays, jokes, code, and more

The model's proficiency is a result of leveraging natural language processing, machine learning, parameters, and trained data to accurately interpret user inputs and generate the desired output. To ensure power and worldwide accessibility, GPT-4 utilizes Microsoft Azure’s AI-optimized supercomputers.

The key features of GPT-4 include:

  • Reinforcement learning from human feedback (RLHF): The model was trained to maximize human satisfaction by incorporating feedback from users interacting with it during development. This process refined GPT-4's outputs.
  • Few-shot learning: GPT-4 can learn new concepts from just a few examples, which helps expand its knowledge base.
  • Multitask training: The model was trained concurrently on a wide variety of NLP datasets spanning translation, question answering, and many other tasks. This improved its general abilities.

However, GPT-4 does not always verify the accuracy of the information it utilizes in its responses. This means that while GPT-4 can generate code with high accuracy, it might not always be the most reliable source when it comes to factual accuracy.

GPT-4 is available within the ChatGPT Plus subscription, which significantly improves its value to non-API users. Anyone can generate images, code, and graphs in the ChatGPT ecosystem now.

The API is available with a maximum context window of 32k tokens, approximately 24,000 words. Fine-tuning is available within the API platform.

Claude 2: Anthropic's Safe and Ethical AI Model

Claude 2 describes itself

Claude 2 is an AI model developed by Anthropic, emphasizing safety, efficiency, and ethical considerations.

It provides secure output generation and large context windows, with inputs of up to 100k tokens, approximately 75,000 words. This is much larger than GPT-4 and outcompetes pretty much all competitors.

Claude 2 uses latest technologies like natural language processing (NLP), machine learning and reinforcement learning with the help of human feedback. This helps in increasing its accuracy for efficient performance. Anthropic’s agenda is to engineer AI models that are both efficient and secure while adhering to ethical standards.

The key features of Claude-2 include:

  • Reinforcement learning from debate (RLD): Claude 2 engages in automatic debates during training to highlight potential biases and mistakes in its reasoning. This acts as adversarial training.
  • Data filtering: Potentially harmful training data is filtered out to prevent Claude 2 from learning or repeating dangerous information.
  • Truthful modeling: The model is optimized to avoid deceiving users or generating false information. This encourages honest, accurate responses.
  • Ethics tuning: Claude 2 receives ongoing adjustments from AI trainers to strengthen its moral reasoning in areas like fairness and avoiding harm.

In the next two years, Anthropic plans to raise up to $5 billion to develop “Claude-Next,” which is estimated to cost $1 billion and is anticipated to be 10 times more powerful than existing AI systems.
