UNC-Chapel Hill's AIMING Lab has released MetaClaw, an open-source meta-learning framework that continually evolves AI agents by using conversations with users as a learning signal. It requires no GPU cluster and can be attached to existing agents as a proxy.

MetaClaw: an agent that meta-learns just by talking

A framework that keeps AI agents evolving after deployment — pairing instant skill synthesis from failed trajectories with reinforcement learning that runs during your idle time, no local GPU required.
