Artificial Intelligence tools are taking the centre stage in our lives in day to day activities. From studying to writing research paper, every task involves AI. In this regard, two of the main giants in the AI field - OpenAI and Anthropic are always indulging in head to head competition. Both companies recently launched their new AI models.
OpenAI launched ChatGPT 5.5 and Anthropic launched Opus 4.7. The two companies launched their model with an aim to make daily work useful, coding can be easily done, and they can help in problem-solving. Nevertheless, both the models have different approaches, where one focuses on speed and task completion, and other is based on careful thinking and detailed answers.
My article will explain how both the models perform and how they can be understood in simple terms.
ChatGPT 5.5 vs Open 4.7: Price and Availability
The first comparison that we will delve into comes on pricing and availability. Both models are not free for all users, and hence you will have to pay some subscription money to use the platforms.
Talking about the ChatGPT 5.5, it is available to paid users of ChatGPT, including Plus and Pro members. The model is also equipped with the different version that is designed for deeper thinking and better performances.
On the other hand we have Opus 4.7, which is available to users with higher subscription plans like Pro and Max.
Interestingly, both the models are built to provide developers with API access, meaning if you are a developer then you can use both the models in your apps.
In terms of pricing, both models have similar starting price for input tokens.
For example: ChatGPT Plus comes with Rs 1999 per month and ChatGPT Pro is available with Rs 10,699 per month. For using ChatGPT 5.5, you have to have the subscription of both these plans.
For Opus 4.7:
Input Tokens: $5 per million tokens (approximately 415 to 465 per million).
Output Tokens: $25 per million tokens (approximately 2,075 to 2,325 per million).
ChatGPT 5.5 vs Opus 4.7: Performance Analysis
To understand which model is better, I gave prompt to both the models and tested their output. My prompt included logic, reasoning, and real-world problems.
Prompt:
"A shop sells three types of pens: cheap, medium, and premium. The probability of picking each pen is equal. The cheap pen works 50% of the time, the medium pen works 80% of the time, and the premium pen always works. If you pick a pen and it works twice in a row, what is the probability it will work the third time?"
ChatGPT 5.5 vs Opus 4.7 Response
ChatGPT-5.5 gave a simple explanation. It explained the steps and provided a final answer. The answer was not too technical and helpful for someone who is beginner in coding.
But Claude Opus 4.7 also gave the correct solution and more detail. It went into a little more detail how probability works and how the formula works in general.
In this particular case, Claude was better because it went into more detail about the reasoning, whereas ChatGPT was more succinct.
