Deep Reinforcement Learning in the Era of Foundation Models: A Survey
Deep reinforcement learning (DRL) and large foundation models (FMs) are synergizing to redefine modern AI. This survey comprehensively reviews their growing convergence, examining how techniques like RLHF, RLAIF, world-model pretraining, and preference-based optimization enhance FM capabilities. We present a taxonomy of integration pathways—model-centric, RL-centric, and hybrid—and synthesize applications across language agents, autonomous control, scientific discovery, and ethical alignment. The review also identifies key challenges in scalability and reliability, while outlining future research directions for building trustworthy, reinforcement-driven intelligent systems.

Core DRL-FM Integration Paradigms
The integration of DRL and FMs can be categorized into three primary paradigms based on how learning, perception, and reasoning are coupled within the reinforcement loop. These distinct approaches enable various forms of intelligent agent behavior, from specialized control to broad generalization and alignment.

Policy Optimization Methods for FM Alignment
Policy optimization is crucial for translating learned rewards into improved model behavior. In the context of foundation models, reinforcement learning fine-tunes pretrained policies, balancing reinforcement signals with deviation constraints from reference policies. Key methods include PPO, DPO, and IPO, each with distinct trade-offs in stability, sample efficiency, and hyperparameter sensitivity, as summarized in the table below.
| Method | Key Principle | Advantages | Limitations |
|---|---|---|---|
| Proximal Policy Optimization (PPO) | On-policy gradient ascent with clipped updates and KL penalty. |
|
|
| Direct Preference Optimization (DPO) | Closed-form objective optimizing preference log odds. |
|
|
| Implicit Preference Optimization (IPO) | Implicitly optimizes pairwise preference likelihood via reparameterized gradient. |
|
|
| Offline RL | Optimizes policy from static datasets using precomputed feedback. |

Case Study: Language and Multimodal Agentic Systems
Language-first agents are a central proving ground for reinforcement-based refinement of foundation models. RLHF, DPO, and other reinforcement-driven methods enable generative models to align with user expectations, perform complex tool use, and interact autonomously in dynamic environments. This section highlights how DRL provides the corrective signals for stable reasoning and multi-step interaction.
Advancing Agentic Behavior with DRL
The integration of DRL with FMs has transformed language models into action-capable systems. Systems like Voyager [52] demonstrate curriculum-driven RL for lifelong skill acquisition in open-ended environments like Minecraft, significantly accelerating competence acquisition over imitation-only baselines. PaLM-E [50] and RT-2 [51] embed continuous perceptual signals into LLMs, enabling zero-shot transfer of knowledge from vision-language tasks to robotic manipulation. These agents leverage pretrained representations for broad generalization, while DRL provides the fine-grained action grounding necessary for real-world interaction and tool use, moving beyond passive generation to utility-driven autonomous behavior.
Critical Challenge: Optimization Instability
A core difficulty in DRL-FM integration is the instability of reinforcement-based optimization when applied to foundation-scale policies. Algorithms like PPO and DPO are highly sensitive to hyperparameters, reward shaping, and minor errors in reward model predictions, often leading to reward hacking or unpredictable behavioral drift in high-dimensional policy spaces. This challenge becomes more pronounced as model size increases, necessitating robust mechanisms for consistent improvement during iterative alignment and deployment.
