    The AI angle

    OpenAI API vs AI

    AI augments this tool
    Go further with AI

    The OpenAI API is the infrastructure that lets thousands of products (from Notion AI to GitHub Copilot) integrate GPT models — a development need rather than an end-user-facing product.

    Can AI replace it?

    Replace the OpenAI API with an AI? The question is inverted: it's the infrastructure that LETS other products integrate AI, not a product to replace. Verdict: the API augments the capabilities of products that integrate it, it doesn't compete with them.
