Key Points


1. The paper discusses problems given to GPT-4 to solve to evaluate its logical reasoning abilities.

2. The first problem revolves around seating arrangements, where GPT-4, a language model developed by OpenAI, is given a simple puzzle about seating arrangements. GPT-4 is found to both make mistakes and correct its errors when pointed out.

3. Another challenge provided to GPT-4 discusses Nancy and Tom's commutes to work, and GPT-4 is found to fail in deducing sound conclusions based on the information provided.

4. The paper evaluates GPT-4's logical reasoning by examining various problems and the model's responses, indicating when the model makes correct deductions and when it fails to do so.

5. The paper also evaluates GPT-4's comprehension of a logical puzzle involving Aunt Agatha, Charles, and the butler, pointing out both correct and erroneous deductions made by the model.

6. Furthermore, the paper assesses GPT-4's ability to solve complex reasoning problems such as temporal reasoning problems and logical deductions, noting both accurate and erroneous conclusions made by the model.

7. The paper also discusses flaws in GPT-4's interpretations of premises and logical reasoning problems and how the model attempts to correct its mistakes when they are pointed out.

8. Finally, the paper evaluates GPT-4's proficiency in solving problems related to expressions, compilers, and proofs, highlighting both accurate and inaccurate deductions made by the model and its ability to correct errors when they are pointed out.

Summary

The paper critically examines the reasoning capability of GPT-4, a state-of-the-art language model. It begins by praising the substantial improvement of GPT-4 over its predecessor, GPT-3.5, but expresses skepticism about GPT-4's ability to reason. The author criticizes the current evaluation of reasoning performance in language models and introduces 21 diverse reasoning problems to qualitatively analyze GPT-4's performance. The paper argues that, despite occasional flashes of ingenuity, GPT-4 is currently incapable of reasoning due to fundamental flaws in its explanations and proof attempts.

The paper discusses the nature of reasoning and methodology, focusing on deductive reasoning and the process of drawing and justifying conclusions from a given body of information. It highlights the shortcomings of GPT-4 in performing basic arithmetic operations and concrete counting, which are deemed necessary for a reasoning system. The paper presents several interactions showing GPT-4's failure in basic arithmetic, concrete counting, and logical reasoning, including its inconsistency, confusion, and inability to provide correct responses to logical queries and problems.

Furthermore, the paper discusses the circularity in using language models for reasoning and planning, highlighting the computational complexity of planning and the impracticality of delegating reasoning to specialized agents. It also addresses the limitations of GPT-4 in understanding quantifiers and quantified statements. The author demonstrates GPT-4's inability to correctly prove or disprove logical claims, highlighting its flawed reasoning and contradictions in explanations.

In conclusion, the paper provides a detailed qualitative analysis of GPT-4's performance on a variety of reasoning problems and interactions, ultimately concluding that GPT-4, despite its improvements over previous models, is currently incapable of reasoning due to its pervasive errors, flawed explanations, and inability to provide logical conclusions or justifications.
