Yes, the ratio is pretty low for DeepMind. Higher for Google Brain. Still, DeepMind open-sourced two major frameworks: Sonnet (general DL) [0] and DeepMind Lab (RL environment) [1].

Frameworks != reproducible results. Ideally, they'd release all the code you need to get the results from the DDPG paper. I recognize that the code probably depends on proprietary DeepMind tools, making this not feasible. Still, it sucks.
