Open source is in general wrong term in all of these “open source” LLM’s (like LLAMA and R1), the model is shared, but there is no real way of reproducing the model. This is because the training data is never shared.

In my mind open source means that you can reproduce the same binary from source. The models are shared for free, but not “open”.

Trains in Nordic have been electric for a generation, starting from 60’s.

Busses have been mostly electric in my knowledge about 10 years, I think most of them are ran by electric motor, which is charged with diesel if batteries run out.

Trams and metros have been electric for last 100 years.
