At standup, a dev mentions hosting a small interactive demo of a machine learning model directly from a repository, accessible via a shareable URL. What is this hosting feature called?
A hosted model demo, or Space, packages a small interactive application, often built with a lightweight UI framework, around a machine learning model and hosts it directly from a repository, giving anyone a shareable URL to try the model without setting up any code locally. This dramatically lowers the barrier for others to explore a model's capabilities firsthand. It's a common way for researchers and teams to showcase a model's behavior interactively rather than only through a static paper or README.

During a design review, the team wants their demo to run on a GPU rather than a slower CPU instance, for a model too large to run efficiently otherwise. Which capability supports this?
Configurable hardware tiers let a hosted demo run on more capable hardware, like a GPU-backed instance, when the underlying model is too large or slow to run efficiently on a basic CPU instance. This flexibility means a demo's hosting can be matched to the actual computational needs of the specific model being showcased. Larger, more compute-intensive models generally require this upgraded hardware tier to remain responsive for demo visitors.

In a code review, a dev notices the demo's underlying model can be swapped out by simply updating a repository reference, without rewriting the surrounding demo application. What does this represent?
Decoupling the demo application from the specific model artifact lets the underlying model be swapped by updating a reference, rather than requiring the surrounding application code to be rewritten every time a new model version is tested. This separation makes it much faster to iterate on model versions while reusing the same demo interface. It reflects good separation of concerns between the presentation layer and the underlying model being showcased.

An incident report shows a public demo was inadvertently left configured with unrestricted usage, resulting in unexpectedly high compute costs from heavy public traffic. What practice would prevent this?
Configuring usage limits or access restrictions before publishing a public demo prevents unexpectedly high traffic from driving up compute costs beyond what was anticipated. Assuming traffic will naturally stay manageable, with no limits or monitoring in place, is how a demo that goes even modestly viral can generate a surprising bill. This kind of cost guardrail is a reasonable precaution for any publicly accessible, compute-backed demo.

During a PR review, a teammate asks why the team publishes a hosted interactive demo instead of just sharing the model's code repository for others to run locally. What is the reasoning?
Sharing only a code repository requires anyone interested to clone it, install dependencies, and likely download model weights before they can try it, which is a real barrier for a casual visitor. A hosted demo removes all of that setup, letting someone try the model instantly through a browser. This accessibility tradeoff comes at the cost of ongoing hosting and compute expense that a code-only repository doesn't incur.
