Great questions.

1. The truth is we still have to investigate the the numerical stability of these models. Our GFT forecast rollouts are around 2 weeks (~60 steps) long and things are stable in in that range. We're working on longer-ranged forecasts internally.

2. The compute requirements are extremely favorable for ML methods. Our training costs are significantly cheaper than the fixed costs of the supercomputers that government agencies require and each forecast can be generated on 1 GPU over a few minutes instead of 1 supercomputer over a few hours.

3. There's a similar floating-point story in deep learning models with FP32, FP16, BF16 (and even lower these days)! An exciting area to explore
