Here is the explanation: Pickaxe uses the OpenAI and Anthropic models via API, meaning we’re accessing the actual models. ChatGPT and Claude.ai are both the company’s own implementation of their own model. For example, ChatGPT is OpenAI’s implementation of their own foundational AI model. It’s like a general-purpose Pickaxe OpenAI built on their own model. ChatGPT operates with a system prompt that OpenAI wrote themself. Using parts of this prompt can help you replicate small behavioral differences between your Pickaxe and ChatGPT.
We explain and break the differences in this post for Claude and in this post for ChatGPT.
