Language models have become the go-to technology for chatbots and virtual assistants, handling basic tasks like generating text and answering straightforward questions. However, when it comes to solving complex problems in areas such as drug discovery, materials science, or advanced coding, these models fall short.
This is where OpenAI’s new o1 model series comes in. By shifting focus from simple language tasks to complex reasoning, o1 aims to bridge the gap and make AI a valuable tool for tackling sophisticated, real-world challenges.
In this week’s dispatch, we’ll explore what makes the OpenAI o1 series different, its unique training approach, and how it could transform knowledge work in fields like scientific research and mathematics.

Why OpenAI o1 Series: What Makes It Different?
The o1 series, which includes both o1-preview and o1-mini, is a product of OpenAI’s continuous effort to develop more intelligent and versatile models. It is specifically built to think more, and reason.
The model o1 is trained using a completely different method than the previous GPT models, and simultaneously, the way it processes your queries is different as well.
Let’s first understand how it has been trained differently.
1. Chain-of-Thought Reasoning:
The OpenAI o1 models introduce a novel approach known as “chain-of-thought” reasoning, which enables them to break down complex problems into smaller, more manageable steps.
This method allows the models to handle intricate tasks that require multi-step reasoning, such as solving advanced mathematical problems, debugging complex code, or conducting in-depth scientific analysis.
As the model breaks down a task, reflects on it, or sets a plan to execute it, it tends to get a deeper understanding and hence better reasoning, much like what humans do.

2. Smarter Training with Human Guidance:
The OpenAI o1 models are trained with reinforcement learning with human feedback (RLHF). This means they’re not just learning to generate text; they’re learning to think in ways that align with human reasoning and values. This training helps them navigate complex queries more effectively, adhering to nuanced safety and ethical guidelines, making them more reliable and trustworthy in sensitive applications.
3. Hidden Thought Process:
A unique aspect of the OpenAI o1 series is its use of “reasoning tokens.” These tokens let the model internally explore multiple approaches before finalizing a response, kind of like brainstorming different solutions before settling on the best one. While you don’t see this internal process, it results in a more thoughtful and refined answer without overwhelming users with too much information.
4. Strategic Use of Compute Power:
o1’s strength also lies in how it uses computational resources. Traditional models put a lot of emphasis on the pretraining phase, but o1 allocates more compute to the reasoning process during both training and inference.
This means it can take the time to think through a problem more thoroughly, resulting in higher accuracy and more sophisticated reasoning. It’s like giving the model the ability to “pause and think” before answering.
Why It Matters: A New Frontier, But at a Cost
The OpenAI o1 model’s enhanced reasoning capabilities set a new standard for AI, making it a powerful tool for complex problem-solving and not just for smaller tasks like language generation.
Its ability to think through problems step-by-step allows it to excel in areas like advanced coding, scientific research, and strategic planning. This depth of reasoning could transform how AI is used in critical fields, providing more reliable and nuanced insights.
However, these advancements come at a high price—both literally and in terms of speed. The o1 models require significantly more computational resources, making them slower and up to six times more expensive than their predecessors. This makes them less suitable for applications where cost-efficiency and response time are crucial. Despite these limitations, the o1 models’ potential to handle complex, high-stakes scenarios with greater accuracy could justify the investment for those who need advanced reasoning capabilities.
The Incorporation of Agentic Framework in Language Models for Better Performance
The o1 model’s focus on structured reasoning and decision-making highlights the potential of agentic frameworks for more complex tasks. These frameworks enable language models to act autonomously, making decisions and adapting to changing conditions in real-time. By integrating frameworks like planning, memory, and goal-driven behavior, agentic designs allow AI to tackle intricate, multi-step problems more effectively.
Here’s a great talk by the Founder of Coursera, Andrew Ng where he talks about the potential of agentic patterns in AI.
