If you are a passionate user of artificial intelligence, then OpenAI's latest o1 model will undoubtedly become your focus of exploration, with its outstanding reasoning ability being at the forefront of the industry. However, if you are accustomed to other platforms or models, you may be unwilling to register a separate account or subscribe to OpenAI's services. The good news is that there are multiple ways to experience this innovation without any additional burden.

OpenAI is gradually expanding the popularity of the o1 model. Let us pay attention to who can be the first to experience this technological feast and its corresponding costs.

It is worth noting that on Monday, Perplexity's CEO Aravind Srinivas announced through an article that the beta version of Perplexity has integrated the "inference" function, which is powered by OpenAI's o1-mini and designed specifically for Perplexity Pro users, with a monthly fee of only $20. However, considering the speed of o1's processing, Srinivas suggests that users use Perplexity more for puzzles, mathematical calculations, and programming assistance, rather than daily searches. Perplexity Pro users are limited to using this function 10 times per day and have access to top AI models such as GPT-4o, Claude 3 Sonnet/Opus, and Sonar Large 32k based on Llama 3 70b.

On the other hand, You.com also offers OpenAI's o1-preview and o1-mini as part of its Pro plan, with an annual fee of only $20. Although the specific usage restrictions are not detailed, You.com's significant advantage lies in its inclusion of almost all mainstream artificial intelligence models on the market, such as GPT-4o, Clade 3.5 Sonnet, Llama 3, Mistral Large 2, Gemini 1.5 Flash, and Command R, providing users with a wide range of choices.

Of course, the most direct and convenient way to access the o1 model is through ChatGPT. All users can experience o1-mini without any threshold, while ChatGPT Plus users enjoy the additional benefit of 50 messages per day. The specific limitations for free users have not been announced yet, but they are expected to be stricter. In addition, ChatGPT Plus subscribers can also obtain the limited usage rights of 50 o1-preview messages per week for an additional $20 per month, and enjoy many privileges including unlimited data analysis, file uploads, visual assistance, web browsing, and custom GPT creation.
