Reinforcement learning

As explained in Sutskever's List

Machine learning in which an agent learns behavior through rewards or penalties from interaction with an environment.

Reinforcement learning is a way for an agent to learn behavior through rewards or penalties as it interacts with an environment. At OpenAI, it became an early research priority: the lab built OpenAI Gym to accelerate research and pursued AI-driven gameplay, including Dota 2. section 1.1

These efforts preceded a shift toward focused Transformer experiments and the 2018 release of GPT-1. The sequence shows reinforcement learning as one part of OpenAI’s early, broad exploration, not as an explanation of how its language models were trained. section 1.1

How Sutskever's List covers it

How deep it goes
Mentions the approach and its applications but does not explain training algorithms or reward design.
Examples
Cites OpenAI Gym and AI-driven Dota 2 gameplay as early milestones.
What you can do after
Evaluate/understand it as an early research direction at OpenAI rather than implement a reinforcement learning algorithm.
How it connects
Links reinforcement learning to OpenAI Gym and AI-driven gameplay, then contrasts that phase with Transformer research.
