18,774,405 PyPI downloads of `keras` in the trailing 30 days, which clears the top band of the software usage scale, over 10M a month, level 5. That is the same band other products on this map hold at comparable volume - pydantic-ai at around 31M, llama-index at around 10.18M. Keras is the standard high-level training API across TensorFlow, JAX and PyTorch.
