RL²: Fast reinforcement learning via slow reinforcement learning
OpenAI's RL² proves neural networks can learn to learn—cutting adaptation time from hours to minutes.
Why it matters
OpenAI demonstrates a foundational capability for AI agents: meta-learning through reinforcement learning. RL² shows that models can be trained to rapidly adapt to new tasks without retraining, a critical breakthrough for practical AI deployment at scale.
