Completing complex RL training in 15-20 minutes puts high demands on the real-time nature of monitoring alerts. Has their training pipeline been standardized? If training fails or model drift occurs, are there mechanisms for automatic rollback and anomaly detection?

This noise metric... personal training agents have pretty high demands for power efficiency. If the chip process variation isn't controlled well, that 15-minute complex RL run is probably going to blow a capacitor.

With such massive funding yet emphasizing "personal training," it feels somewhat disconnected from the open-source community vibe. If you really want to make Agents trainable, start by making the contribution guidelines and community governance transparent. Otherwise, even strong tech is just building in isolation.
