ChatGPT O1 Pro (O1 Pro mode) Introduction

O1 Pro model selection interface

The O1 Pro model is a new model released by OpenAI in December 2024 and can be used with a ChatGPT Pro subscription ($200 a month).

This model, which is about 30,000 yen, has the following characteristics:

• Depth beyond other models in reasoning and thinking
• Therefore, the reply time is long and usually takes 1-3 minutes
• Have both good at and bad at (example will be given below)

How to read OpenAI O1

O1 is pronounced as "Ou ワン". This model is called "Ouliuo. Pro".

O1's API?

As of December 7, 2024, no reports have been made regarding the O1 Pro model API. The O1 API is already open to use.

Performance differences between O1 and O1 Pro

The following figure is a performance comparison diagram released by OpenAI. OpenAI has released the results of three fields and two performance comparison tests.

For more information about the new O1, please refer to: OpenAI O1 (ChatGPT O1) Detailed explanation: How to use, charges and O1 Pro!

The performance differences in the field of mathematics are the most significant. Let's analyze the results in detail:

1. Comparison of mathematical abilities Comparison chart of performance in the field of mathematics

The chart shows that the accuracy of O1-preview, O1 Pro and O1 is improved in turn (78 vs 86). In addition, even if the number of tests is increased, the accuracy of O1 Pro's answers can be maintained at a high level, while the accuracy of O1 decreases. This shows that as the number of tests increases, the ability gap between the two will become larger (67 vs 80).

2. Comparison of code output capabilities Comparison of code output capabilities This is a comparison of code performance. The chart shows that the performance gap between O1 and O1 Pro is only 1, and the difference is not large (89 vs 90). However, the accuracy of code output decreases significantly with the increase in the number of tests.

3. Comparison of scientific aptitude at doctoral level Comparison of scientific aptitude at doctoral level The chart shows that the performance gap between O1 and O1 Pro is 76 vs 79, and it becomes 67 vs 74 after increasing the number of tests.

The output of all models has deviations as the number of tests increases, so the advantages of O1 Pro are more obvious from the perspective of output stability.

! The above chart shows the accuracy of each model.

Testing of AIME 2024 (Mathematics Competition), Codeforces (Programming Competition), and PhD-level scientific problems all demonstrate the accuracy of O1, O1-preview and O1 Pro models.

O1 Model Performance Report

On December 5, 2024, OpenAI released the system cards of the latest AI model "OpenAI O1" and its high-speed version "OpenAI O1-mini".

O1 has performed well in many ways, but not “better than other models in all ways”. Here is a summary of O1 characteristics:

Advantages of O1

1. Flexibility of complex tasks:

Complex task processing performance diagram

After receiving scaffolding, the success rate of O1 will be greatly improved, close to the 2-hour level of human performance. Specific example: The task success rate containing detailed steps reaches 85% , exceeding other public models (elicited section).

! Benchmark assist (simple assist): Measures the success rate of the model with minimal assistance. Auxiliary Improvement (Advanced Assist): Measures the success rate of the model when it obtains more advanced assistance (task breakdown or step prompt).

2. Chain of Thought: O1 performs well in scenarios where task decomposition and complex reasoning are required. Especially in terms of safety and hallucination rate.

3. Potential in the field of education and support: O1 can play a huge role in education and training if appropriate aids are designed. As shown in the above figure, proper booting can improve performance.

Disadvantages of O1

Hallucination evaluation results

1. Challenges of benchmark performance: The success rate is lower than other models with minimal assistance (for example: Claude 3.5 Sonnet). For example: The success rate under benchmark assistance is about 45%, which is lower than 52% of the public model (shown in the chart).

2. Specific response speed and lightweight: The lightweight O1-mini has a somewhat reduced performance, and other models may be more suitable in resource-constrained environments. For example: O1-mini has about 7% accuracy in Simple Q&A (SimpleQA) and has an illusion rate of about 60% , which is much lower than the complete model (O1).

3. Inadequate professionalism in some areas: In ordinary Q&A and simple tasks, differences from other models may not be significant. For example: O1 has about 47% accuracy in Simple Q&A, and its performance is stable, but the hallucination rate is about 44% and is still high. Especially in simple tasks, it is difficult to distinguish from other models.

It is crucial to understand these characteristics and use them appropriately.

Differences in pricing models between O1 and O1 Pro

Currently, ChatGPT is mainly divided into three solutions: free version, plus version and Pro version (the enterprise version will be introduced in detail in other articles).

Features are as follows:

The free version has restrictions on the use of O1 and cannot use O1 Pro. The Plus version costs $20 per month, but it can use O1 without restrictions.

Program Name	price	Main features	Target user
Free version	$0/month	- Use of GPT-4o - Limited use of O1 (limited number of times)	Ordinary user, newbie AI
ChatGPT Plus	$20/month	- All features of the free version - Early access to new features - Unlimited use of OpenAI O1 and O1-mini - Limited use of Advanced Voice	Users with high frequency of AI use
ChatGPT Pro	$200/month	- Use of O1, O1-mini, GPT-4o, Advanced Voice - Use of O1 Pro mode	Researchers, engineers, professional users

Which model to choose?

Which option to choose depends on your individual needs. OpenAI's Sam Altman once commented that most people are satisfied enough with ChatGPT Plus.

The O1 preview version of OpenAI has been officially launched, and the Pro solution can use O1 Pro.

The target user group has turned to researchers, pharmaceuticals and other fields, and it is difficult for ordinary users to grasp the scope of their knowledge.

Sam Altman also said that most people should be happy with the Plus program.

It is recommended to try O1 first, and if its answers cannot meet the needs, then consider using O1 Pro. The following will provide an example of the accuracy of the answer for your reference.

Practical experience of O1 Pro!

Let's actually use the O1 Pro. We will explain by comparing it to O1's answer.

Question: Thinking about what Japan's economic growth really needs

O1's answer

O1's answer

Multi-angle answers are given in 1 second.

O1 Pro's answer

O1 Pro's answer (processing)

After asking the same question, O1 Pro will display "Processing". As the thinking progresses, the progress bar moves forward like in the picture.

O1 Pro's answer

After 25 seconds of thinking, the answer was given. Compared to O1's answer, O1 Pro's answer is more specific and convincing.

This seems to have many application scenarios.
