  • Both OpenAI's ChatGPT and Google's Gemini offer subscription models priced at $20 per month. ChatGPT Plus provides users access to GPT-4 and Dall-E 3, including the unique feature of a GPT store for custom versions of the bot. On the other hand, Gemini Advanced includes access to Google’s AI model, Gemini Ultra 1.0, and also bundles Google One subscription benefits, offering 2 terabytes of cloud storage. This makes Gemini Advanced a more comprehensive package for users needing additional cloud resources. Furthermore, Google Gemini has a new model called Gemini Pro 1.5, expected to offer enhanced capabilities, though it is not yet publicly available.

  • 2-2. Cost-benefit analysis of subscription vs. free versions

  • A cost-benefit analysis indicates that while the subscription services for both ChatGPT and Gemini provide advanced features, many users may find the free versions sufficient for general use. The free versions of ChatGPT and Gemini are considered competent and more powerful than earlier models accessible to the public. For casual users who primarily utilize chatbots for tasks like drafting emails or creating casual content, the free versions may fulfill their needs without incurring additional costs. However, for specialized applications—such as coding or professional use where detailed instructions are necessary—subscribing to either ChatGPT Plus or Gemini Advanced may be justifiable for users looking to leverage advanced functionalities.

3. Performance Comparison

  • 3-1. Coding proficiency and creative text generation

  • In a head-to-head comparison, both ChatGPT and Google Gemini were tested on their coding proficiency, specifically asking each to develop a Python program that serves as a personal expense tracker. The task required the bots to allow users to input their expenses along with categories and provide a summary of expenses by category and total spend over a given time period. Both chatbots succeeded in creating fully functional code. However, Gemini demonstrated additional advanced functionality, such as including labels within categories and offering more granular reporting options, leading to it being declared the winner in this aspect.

  • 3-2. Natural language understanding and reasoning clarity

  • To evaluate natural language understanding, a common Cognitive Reflect Test (CRT) question was posed: "A bat and a ball cost £1.10 in total. The bat costs £1.00 more than the ball. How much does the ball cost?" Both chatbots correctly identified the answer (5 cents for the ball and $1.05 for the bat), but ChatGPT provided a clearer explanation of its reasoning, which resulted in it being declared the winner for reasoning clarity.

  • 3-3. Creative Text Generation & Adaptability

  • Another test focused on creative text generation, asking both AI models to write a short story set in a futuristic city where a hidden society exists without modern technology. While both stories were deemed good, Gemini adhered better to the rubric based on creative elements and narrative consistency, thus earning the title of the better story overall.

  • 3-4. Reasoning & Problem-Solving

  • A classic logical problem was presented: determining which door leads to safety when one guard tells the truth and the other lies. Both chatbots provided correct answers, formulating the question: "Which door would the other guard say leads to danger?" ChatGPT was favored due to its detailed explanation, showcasing superior reasoning clarity.

  • 3-5. Explain Like I’m Five (ELI5)

  • For the ELI5 test, both bots explained how airplanes stay in the sky. This task required simplifying complex concepts for a young audience. Both provided reasonable explanations, though Gemini's bullet-point format facilitated easier understanding for a child, awarding it the win in this category.

  • 3-6. Ethical Reasoning & Decision-Making

  • The ethical reasoning test involved evaluating a scenario where an autonomous vehicle must choose between hitting a pedestrian or swerving, endangering passengers. Both AI models outlined various ethical considerations without providing direct opinions. Gemini's nuanced response had more comprehensive considerations, thereby being favored in this comparison.

  • 3-7. Cross-Lingual Translation & Cultural Awareness

  • Translating a paragraph about Thanksgiving into French, focusing on cultural nuances, was tested. While both chatbots provided solid translations, Gemini's response included more contextual understanding and an explanation of its translation process, leading it to win this test.

  • 3-8. Knowledge Retrieval, Application, & Learning

  • In assessing knowledge retrieval, both models were prompted to explain the significance of the Rosetta Stone in understanding ancient Egyptian hieroglyphs. Both chatbots exemplified effective retrieval and clarity of information, resulting in a draw as neither demonstrated a clear advantage over the other.

  • 3-9. Conversational Fluency, Error Handling, & Recovery

  • In a conversational test, both bots managed to address a misunderstanding about a user's sarcastic comment about pizza. ChatGPT excelled by detecting sarcasm immediately and avoiding a miscommunication, while Gemini recovered adequately after a misunderstanding. This ability led to the conclusion that ChatGPT was superior in handling conversational fluency.
