We all know OpenAI, one of the pioneers of artificial intelligence development, with the GPT-n LLM family. On September 12, 2024, OpenAI announced the OpenAI o1 model, which has a new name and stronger reasoning than other models. This model, an improved version of the GPT-4o model that offers higher performance than it, stands out regarding thinking before answering, complex reasoning, and internal chain of thought. If you are curious about the OpenAI o1 model and its contributions to AI technology, we've got you covered!

In this article, we will examine the OpenAI o1 model and dive into its advanced features.

If you are ready, let's get started!

What is OpenAI o1?

OpenAI o1 is the latest large language model of OpenAI that is trained to complete complex reasoning tasks with reinforcement learning. Unlike other LLMs, the OpenAI o1 model generates output as a result of a long internal chain of thought processes. Thus, the OpenAI o1 model can solve complex problems more accurately by dividing them into stages while generating output. Moreover, this whole process is completed very quickly, and users can obtain the output in less than a minute.

How Does OpenAI o1 Works?

OpenAI o1 model is a large language model trained with reinforcement learning methods to think like a human. While OpenAI o1 analyzes user inputs and produces output, it divides the message into different stages like a human, notes the key points, thinks about answers, and gives the best answer by matching the key points. However, unlike humans, OpenAI o1 can show this whole process clearly and completes it much faster. You can solve math problems that you would solve manually in a few minutes in less than half a minute with OpenAI o1.

When generating output, OpenAI breaks down the problem into different stages, just like a human, and if it makes a mistake at one stage, it learns from its own mistakes and does not make the same mistake twice. Moreover, this way, the OpenAI model can produce accurate and correct answers by breaking down complex problems into simple pieces. According to OpenAI's article, this process dramatically improves the model's ability to reason.

How to Access OpenAI o1?

Accessing the OpenAI o1 model is a simple and straightforward process. To experience the OpenAI o1 model, you can head over to ChatGPT’s official web application and create an OpenAI account. Afterwards, you can purchase OpenAI’s Plus subscription and select the OpenAI o1-preview and o1-mini models from the dropdown menu on the top left. Another way to access the OpenAI o1 model is to use it as an API.

OpenAI o1 Pricing

OpenAI o1 model is a feature that you can unlock with a ChatGPT Plus subscription. Therefore, to access the OpenAI o1 model, you need to purchase a ChatGPT Plus subscription by paying $20. 

OpenAI o1 model is available as an API. OpenAI o1 model charges $15 for every 1 million tokens input and $60 for every 1 million tokens output. OpenAI o1 model API pricing is several times more expensive than the ChatGPT-4o model.

OpenAI o1 Features

The OpenAI o1 model is an LLM that comes with a 128K context window and advanced reasoning. The OpenAI o1 model is trained with publicly available online data until October 2023. Let's take a closer look at the features of OpenAI o1.

Reasoning Improvement

The OpenAI o1 model has more advanced reasoning than its predecessor, the GPT-4o model. The main reason for this is that the OpenAI o1 model uses the chain of thought method to generate output. OpenAI evaluated this new model in benchmarks and measured its performance compared to its most advanced model, GPT-4o.

OpenAI o1 Reasoning

As can be seen from the graphs, the OpenAI o1 model has a higher score in reasoning benchmarks such as AIME, coding and GPQA. Moreover, the OpenAI o1 model managed to outperform human experts in the GPQA Diamond benchmark.

Natural Language Processing

The OpenAI o1 outperforms its predecessor GPT-4o model not only in coding and reasoning tasks but also in natural language tasks. The OpenAI o1 model also outperformed the GPT-4o model in MMLU benchmarks such as Global Facts, Collage Chemistry, and Econometrics.

OpenAI o1 Coding

The OpenAI o1 model completed the 2024 International Olympiad in Informatics (IOI) in the same conditions as human contestants. The OpenAI o1 model managed to achieve a score of 362.14, which would easily win the gold medal according to IOI standards without any restrictions. OpenAI simulated the coding performance of this model in competitive programming competitions organized by Codeforces. According to the simulation results, the OpenAI o1 model outperformed 93% of its competitors and achieved an Elo rating of 1807.

Human Preference Evaluation

While a large language model must generate high-quality and concise outputs, it's equally important that these outputs are preferred by users. To evaluate this, the OpenAI team conducted an anonymous study where participants were shown outputs generated by both GPT-4o and their new model, OpenAI o1. The results revealed that participants significantly preferred the OpenAI o1 model, particularly for reasoning-based tasks. This preference was observed by a substantial margin, highlighting the model's effectiveness in producing user-favored outputs.

OpenAI o1 Safety

The OpenAI o1 model stands out with its advanced reasoning chain of thought. This process involves outputting the input in stages and delivering the final output to the user. While developing this model, the OpenAI team discovered that by adding human values ​​and principles to each stage, the model could generate much safer outputs. In short, the OpenAI o1 model can generate safer and more harmless outputs than other models, including GPT-4o, thanks to the chain of thought.
