A PyMC model written here, compiled here, sampled here

PyMC runs in this page under Pyodide and builds the graph. The log density is lowered to a tape, tapewasm's emitter turns that into a wasm module, and nuts-rs samples it — all in the tab. Nothing is precompiled and no server is involved. Edit the model, or pick another, and compile it again.

ArviZ

az.summary and arviz-plots themselves: ArviZ came in with PyMC, so the fit becomes an InferenceData in the model's own space. The first press adds plotly for the figures, a few MB.
