    OpenAI Baselines PPO ensures training stability by using a clipped objective function. This function limits the magnitude of policy updates, preventing the policy from deviating too much and causing training instability. The algorithm also employs an actor-critic framework, where the actor (policy network) selects actions, and the critic (value function network) estimates state values to help compute the advantage function for policy optimization.
