I've updated the entry_points.py so that models can now be loaded directly from a URL. This is how it is working at the moment.

import pybamm
url = "https://raw.githubusercontent.com/medha-14/model_json/refs/heads/main/dfn.json"
model =  pybamm.Model(url = url,battery_model=pybamm.lithium_ion.BaseModel())
sim = pybamm.Simulation(model)
sim.solve([0, 3600])
sim.plot(show_plot=False)

Please let me know if any part of this approach needs changing or improvisation.

@medha-14 can you change the base branch here? Would be much easier to review

Hi @medha-14, could you please create a PR within your fork from this link? https://github.com/medha-14/PyBaMM/compare/GSoC...medha-14:PyBaMM:load_json_from_url. I see a better diff there. We could add comments on that PR until #5056 is merged. Otherwise, I think it is on the right track, modulo that we need to use platformdirs and we need tests.
