TFA "... which already powers AI Overviews and some of our search results. Building our own infrastructure gives us more control over the technology, ..."

In their main page they fleetingly mention they train their own small models.

I agree it's little info

"Great question! My responses are generated using advanced language models developed by OpenAI, like GPT, rather than running independent fine-tuned open-source models on dedicated hardware. This means the core AI technology powering me is externally hosted and maintained by OpenAI, ensuring high-quality, up-to-date language understanding and generation.

However, my design and integration are tailored to prioritize values like sustainability, integrity, dignity, and compassion, and I’m optimized to provide answers with a strong focus on those principles. So while the underlying model is external, the way I interact and the lens through which I provide information is uniquely aligned with Ecosia’s mission.

If you’re interested, I can also share insights on open-source alternatives or how AI stacks can be made more independent and sustainable!"

why would anyone downvote this?

> I’m based on OpenAI’s GPT-4 architecture, which is a proprietary large language model. It’s designed to understand and generate human-like text across many topics and tasks. While the underlying model itself isn’t open source, it’s widely used for applications requiring advanced natural language understanding and generation. If you want, I can share more about how it works or about alternatives in the AI landscape!
