• Limited resources: o1-Mini works effectively in applications where computational resources are limited.
• Chatbots: It can power chatbots and virtual assistants, providing quick and accurate responses to user queries.
• Mobile apps: o1-Mini can be used for features like voice assistants, real-time language translation, and camera-based object recognition.
• Education: The model can be used for grading, tutoring, proofreading, and learning analytics in educational settings.
• IoT devices: Its small size makes o1-Mini ideal for Internet of Things (IoT) devices, enabling smart home systems and other connected applications to run efficiently.

How To Use OpenAI O1 Models?

Accessing OpenAI’s O1 models is straightforward, but there are a few steps to follow. 

If you’re using ChatGPT Plus or a team account, you can immediately start using the O1 models. Simply log in to ChatGPT, go to the model picker, and choose between o1-preview and o1-mini. Be aware that these models are yet under development.

Access to the o1 models will be available next week (starting Sept. 16) for ChatGPT Enterprise and Education users. The same model picker will allow you to select the desired model.

If you’re a developer with API access, you can use the o1 models by subscribing to the API tier 5. 

The o1 models are available for prototyping with specific rate limits, so you’ll need to check the API documentation  for details on integrating them into your applications.

For those on the free tier, o1-mini will be available soon, expanding access to these advanced models.

Before you use reasoning models, be mindful that chain-of-thought- is already inherent in these models, so keep your prompts direct and straightforward. Also, avoid mentioning phrases like “give me reasoning,” or “explain why you choose those arguments.” To ensure that the model gives you the best output, your prompts should focus on relevant information. 

Choosing the Right Model

The choice between o1 and GPT-4o models depends upon your specific needs. 

Use o1 Models If:

• Deep reasoning is necessary: o1 models are excellent at managing subtle jobs and reasoning in complex, multi-step processes. They work best in circumstances that call for in-depth comprehension and problem-solving techniques.
• Prefer decreased hallucinations: o1 models use sophisticated reasoning to reduce the rates of incorrect or unsupported information, if decreasing them is important.
• Safety and fairness is your priority: o1 models are a great option for sensitive applications because they offer improved safety features and score higher in fairness assessments.

Use GPT-4o If:

• General versatility: GPT-4o is highly effective for a broad range of tasks including text generation, conversations, and quick responses.
• Advanced tools: If you need access to features like memory, custom instructions, and web browsing, GPT-4o provides these capabilities.
• Real-time applications: GPT-4o might be better for applications requiring fast, responsive interactions or where advanced tools are essential.

Conclusion

With their ability to provide more accurate and reliable results, particularly in intricate and multi-step tasks, the OpenAI o1 models mark a substantial advancement in AI thinking. 

o1 models are superior for activities demanding accuracy and deep understanding because of their greater problem-solving ability, lower hallucination rates, and improved safety features. 

Even if the o1 models might not completely replace GPT-4 just yet—especially for real-time applications or those requiring sophisticated capabilities like web browsing—they are ideal for addressing tasks in domains like STEM, legal analysis, and creative content creation. 

These models present fascinating opportunities for cutting-edge AI-driven solutions, regardless of your role: developer, business, or end user. But remember, humans created AI, so humans still play a crucial role in advancing these models or any other AI use case.
