gives? perhaps it does now, but it was certainly non-determinstic when it was first released, which is also when it was used for policy decisions.

See for example https://news.ycombinator.com/item?id=23099386

But how useful was the model? It showed that the virus would spread exponentially, but we knew that. Is there anything that it showed that we didn't know when they programmed it, with constants tuned to what they expected?

That was the point. They used stochastic partial differential equations, they're by definition non-deterministic.

No, they should be reproducible if run with the same seed.
