The newly launched ChatGPT Pro subscription offers a comprehensive suite of advanced AI capabilities, including:

• Unlimited access to OpenAI's cutting-edge models: o1, o1-mini, GPT-4o, and Advanced Voice12

• Access to o1 pro mode, a more powerful version utilizing increased computational resources13

• Future additions of compute-intensive productivity features2

This premium tier, priced at $200 per month, marks the beginning of OpenAI's "12 days of Shipmas" event, signaling a significant expansion in their service offerings45. The plan is designed to provide users with "scaled access to the best of Open AI's models and tools," catering to those requiring research-grade AI capabilities on a daily basis2.

The o1 Pro Mode demonstrates significant performance improvements over its predecessors, particularly in complex problem-solving scenarios. In benchmark tests, it outperformed both o1 and o1-preview, especially in areas like competition math and coding. For instance, on the AIME 2024 math competition questions, o1 Pro Mode achieved an 86% correct answer rate, compared to 50% for o1-preview12. In coding challenges on Codeforces, it scored 90 points versus 62 for o1-preview1.

The model's enhanced reliability is particularly noteworthy. OpenAI employs a strict evaluation criterion, considering a problem solved only if the model provides correct answers in four out of four attempts3. This "4/4 reliability" metric highlights o1 Pro Mode's consistency in delivering accurate results for challenging tasks. However, it's important to note that the performance gains are most significant for complex queries; for simpler coding tasks, o1 Pro Mode showed a more modest 1% improvement over the standard o1 model4.

The ChatGPT Pro plan is tailored for power users who require advanced AI capabilities in their daily work. Specifically, it targets researchers, engineers, and individuals who need research-grade AI tools for complex problem-solving12. This subscription tier is designed to meet the demands of users who require more computational power and advanced features beyond what the standard ChatGPT Plus offers. By providing unlimited access to OpenAI's most sophisticated models and tools, ChatGPT Pro aims to support users tackling the most challenging problems in fields such as science, mathematics, and coding34.

ChatGPT Pro significantly expands upon the features offered by ChatGPT Plus, providing a more robust and comprehensive AI experience for power users. While ChatGPT Plus, priced at $20 per month, offers priority access and faster response times, ChatGPT Pro takes capabilities to a new level with its $200 monthly subscription12. The Pro plan includes unlimited access to OpenAI's most advanced models, including o1, o1-mini, GPT-4o, and Advanced Voice, as well as the compute-intensive o1 pro mode3. This contrasts with ChatGPT Plus, which primarily offers GPT-4 access with usage limits. ChatGPT Pro is designed for users who require "scaled access to the best of Open AI's models and tools," making it particularly suitable for those tackling complex problems in research, engineering, and other demanding fields34.
