Reinforcement learning only works once a model already knows something, which is why robots must be pre-trained by imitation first.

Shared subject first, then similar wording. They may agree or disagree.

• One pre-trained robot model now matches or beats the specialists that were fine-tuned with reinforcement learning for the very tasks they were built for. CFChelsea Finn12 Aug 2026roboticsreinforcement learning
• Reinforcement learning cannot be scaled for robots the way it was for language models, because every attempt spends real robot hours instead of data-centre compute. CFChelsea Finn12 Aug 2026roboticsreinforcement learning
• A verifiable task can be optimised by reinforcement learning until a neural network performs it extremely well. AKAndrej Karpathy17 Nov 2025reinforcement learning
• Capability does not generalise for free: a model that will move mountains on an agentic task still tells the same bad joke it told five years ago. AKAndrej Karpathy20 Mar 2026reinforcement learning
• Current models are unsafe because they are not smart enough, not because they are too smart. FCFrançois Chollet13 Sept 2026reinforcement learning
