A Deep Dive into the Future of AI: Insights from John Schulman


In the rapidly evolving landscape of artificial intelligence, the conversation with John Schulman, a co-founder of OpenAI, presents a fascinating glimpse into the future. Schulman, a pivotal figure behind the creation of ChatGPT and an author of influential papers on AI and reinforcement learning (RL), offers valuable insights into the distinctions between pre-training and post-training, what future AI capabilities might look like, and the ethical considerations surrounding advanced AI deployment.

Understanding Pre-Training and Post-Training

The Essence of Pre-Training

Pre-training, as Schulman elaborates, is the process where AI models are trained to imitate a vast array of content available on the internet. This includes websites, code snippets, and various forms of digital content. The primary objective during this phase is to maximize the likelihood of accurately predicting the next "token" or piece of data, given the preceding tokens. This foundational stage results in a model capable of generating content that closely mimics human writing across diverse topics.

A critical aspect of pre-training is the model’s ability to assign probabilities to different outcomes, thereby developing a highly calibrated system that can not only generate but also evaluate the likelihood of various pieces of content. This multifaceted foundation sets the stage for the subsequent phase of refining the model’s capabilities.

The Role of Post-Training

In contrast, post-training focuses on narrowing the AI's behavior to fit more specific objectives, such as functioning as a chat assistant. Schulman points out that while pre-training aims to create a versatile model capable of generating a broad spectrum of content, post-training fine-tunes it to be more helpful and user-oriented. The goal shifts from imitating raw web content to producing outputs that are both useful and enjoyable for human users.

This targeted approach in post-training revolves around optimizing the model's responses to align with human preferences, thus transforming it into a more interactive and functional assistant.

Future Capabilities of AI

Evolution Over the Next Five Years

Looking ahead, Schulman predicts significant improvements in AI capabilities within the next five years. He envisions models that can perform more complex tasks autonomously, such as undertaking comprehensive coding projects from high-level instructions to execution and testing. This leap in functionality stems from training models on more demanding tasks and increasing their ability to handle long-horizon activities.

The advancements may include better error recovery, improved handling of edge cases, and enhanced sample efficiency. These developments suggest a future where models can operate coherently over extended periods, thereby executing tasks that currently require substantial human intervention.

The Role of Reinforcement Learning

Reinforcement learning (RL) is expected to play a crucial role in this evolution. Training models through RL to manage longer projects and complex tasks can significantly enhance their capabilities. This approach involves both supervised learning of the final outputs and step-by-step supervision, ensuring that the models learn to navigate various stages of a project efficiently.

Schulman highlights that there is considerable potential in applying RL techniques to AI training, as the field is still relatively nascent. By exploiting these opportunities, models can become adept at generalizing from a few examples and recovering from errors with minimal data.

Addressing Ethical and Practical Concerns

Coherence and Generalization

One of the fundamental challenges in developing advanced AI is ensuring long-term coherence and strong generalization capabilities. Schulman discusses how models trained for coherence over longer periods can potentially reach human-level performance in specific tasks. However, he also notes that the current models still exhibit weaknesses in sustained attention and complex problem-solving.

In terms of generalization, models have shown promising signs of transferring learned behaviors across different languages and modalities. For example, a model fine-tuned on English data can exhibit reasonable performance in other languages and even multimodal tasks, demonstrating the potential for broad applicability.

Ethical Considerations and Safety

The prospect of AI reaching human-level capabilities brings with it significant ethical and safety concerns. Schulman stresses the importance of being cautious in training and deploying advanced models. This includes extensive monitoring during the training process and conducting thorough evaluations to detect any misbehavior or alignment issues.

If advancements in AI capabilities occur more rapidly than anticipated, OpenAI and other organizations would need to consider pausing further training and deployment to ensure safety and ethical compliance. This approach would require coordination among major AI entities to prevent a competitive race that could compromise safety standards.

Preparing for an AI-Driven Future

Coordination and Governance

The potential for AI to reach advanced levels of intelligence necessitates robust coordination and governance mechanisms. Schulman suggests that all major AI developers would need to agree on limits to deployment and further training to avoid unsafe practices. Establishing rules for responsible AI development can help mitigate risks and ensure that AI advancements benefit society responsibly.

Practical Implementation

In practical terms, this means developing robust defense mechanisms, including impeccable moral guidelines for AI behavior and effective monitoring systems. By implementing such measures, AI developers can detect and address unforeseen issues, ensuring that AI systems remain aligned with human values and safety requirements.


John Schulman’s insights offer a profound understanding of the current state and future potential of AI. As we move towards more advanced capabilities, the focus must remain on ensuring ethical considerations and safety protocols are in place. Through careful training, robust monitoring, and global coordination, the promise of AI can be realized in a way that benefits humanity as a whole.
