Markdown versions of documentation pages are available by appending `.md` to page URLs; this page is available as [Markdown](https://cerebro-3.gitbook.io/cerebro-docs/ai-inference-marketplace/why-a-marketplace.md). # Why a Marketplace? AI inference is becoming increasingly fragmented. There are hundreds of models, different providers, different hardware configurations and different pricing structures. A developer may want: > The cheapest model for a simple task. Another may want: > The fastest model available. Another may need: > A specific open-source model running on a specific GPU. Another may simply want: > An AI agent that can automatically choose the best inference provider. A marketplace can allow these different requirements to exist within one economic layer. Cerebro's objective is not to decide which AI model wins. It is to create the infrastructure where different models and inference providers can compete. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://cerebro-3.gitbook.io/cerebro-docs/ai-inference-marketplace/why-a-marketplace.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
