“self-evolves through feedback loops”

Does this mean they distilled Claude? Sounds like what Claude Code will often do.

It's meaningless. Models have always been able to do this and this capability is strengthened during RL since being able to explore the solution space to figure something out will give it a reward.

What is important is how long it can go without requiring human intervention. Not just that it's possible to run on its own for a time.

Of course they did.
