CMU Researchers Introduce miniCodeProps: A Minimal AI Benchmark for Verifying Code Properties

AI agents have recently shown great potential in automating mathematical theorem proving and code correctness verification through tools like Lean. These tools combine code with specifications and proofs to ensure that the code meets its intended requirements, providing strong safeguards for safety-critical applications. With the help of large language models, AI has demonstrated its ability to facilitate core steps in solution development—coding, specifying, and proving. While these advances are promising, fully automating program verification remains a significant challenge.

Traditionally, mathematical theorem proving has relied on tools like Lean, which train models using datasets such as Mathlib to solve problems with specific definitions and strategies. However, these tools have faced difficulties when it comes to adapting to program verification, which requires entirely different techniques. While machine learning has improved automation in systems like Coq and Isabelle, similar advancements for Lean in program verification are still lacking. Although other tools like Dafny, Verus, and benchmarks such as miniF2F and CoqGym offer alternatives, they have not fully addressed the challenge of adapting theorem-proving methods to the requirements of program verification.

To address the challenge of automatically generating proofs for programs and their specifications, researchers from Carnegie Mellon University introduced miniCodeProps, a benchmark featuring 201 program specifications in the Lean proof assistant. The benchmark consists of simple, self-contained programs—such as lists, natural numbers, and binary trees—with varying levels of difficulty for proof generation. miniCodeProps is divided into three categories: intuitive properties of lists, trees, and numbers (medley); termination lemmas for recursive functions (termination); and properties of nonstandard sorting algorithms (sorting).

The functions primarily operate on linked lists, with some involving natural numbers and binary trees. The properties are classified by difficulty: easy (medley), medium (termination), and hard (sorting). Termination lemmas, which are essential for proving recursion termination in Lean 4, add an extra layer of complexity. The dataset, available in jsonlines format, provides crucial information such as the proof state and dependencies for each theorem. Notable examples, like the zip over concatenation property and sorting properties, illustrate the challenges of proving properties, particularly for more complex sorting algorithms.

The evaluation of miniCodeProps focused on two main tasks: full-proof generation and tactic-by-tactic generation. In full-proof generation, models were assessed based on their ability to produce complete proofs for given specifications. For tactic-by-tactic generation, models were tested on their ability to suggest the next appropriate tactic from the current proof state, evaluating incremental reasoning. The evaluation also considered the varying difficulty levels of the proofs, from simple properties of lists and numbers to more complex termination and sorting algorithm properties, measuring both efficiency and correctness in proof generation or tactic application.

The results showed that neural theorem provers, such as GPT-4o, performed well on simpler tasks, achieving a 75.6% success rate on medley properties. However, performance on more difficult tasks, like termination and sorting, was lower, at 4.34% and 6.96%, respectively. The Mathlib-trained model ntp-ctx-1.3B demonstrated similar efficiency to GPT-4o, indicating the potential for domain-specific verifiers to make further progress. MiniCodeProps offers a valuable framework for improving automated theorem-proving agents used in code verification, supporting human engineers and providing additional guarantees through diverse reasoning approaches.

Ultimately, the miniCodeProps benchmark is a valuable tool for advancing automated ITP-based code verification. It features problems from a variety of inductive problem datasets, allowing for incremental progress in verifying program properties. However, the method does have limitations and struggles with more complex problems. Despite this, miniCodeProps holds significant potential to drive advancements in verification agents and can serve as a baseline for evaluating new approaches in automated code verification.

Researchers at Carnegie Mellon University (CMU) have introduced miniCodeProps, a benchmark designed to advance the field of automated code verification. This initiative addresses the critical need for tools that can ensure the correctness of software systems, thereby reducing the risk of bugs and vulnerabilities that can lead to significant real-world consequences.

The miniCodeProps benchmark comprises 201 program specifications within the Lean proof assistant framework. These specifications pertain to simple, self-contained programs involving fundamental data structures such as lists, natural numbers, and binary trees. The primary objective is to evaluate the capability of AI models, particularly large language models (LLMs), in automatically generating proofs that confirm these programs adhere to their specified properties. This approach aims to streamline the verification process, making it more accessible and efficient.

Background

Ensuring the correctness of code is a fundamental challenge in software development, as even minor errors can lead to significant issues, including security vulnerabilities, system failures, and financial losses. The complexities involved in code verification arise from several factors, including the increasing sophistication of software systems, the diversity of programming languages and paradigms, and the limitations of traditional verification methods.

One of the primary challenges in code verification is the inherent complexity of modern software systems. As applications become more intricate, with numerous interacting components and dependencies, verifying the correctness of each part becomes increasingly difficult. This complexity is further compounded by the use of various programming languages, each with its own syntax, semantics, and idiosyncrasies, making it challenging to develop universal verification methods that can be applied across different languages and platforms.

Traditional code verification methods, such as manual code reviews, static analysis, and testing, have been foundational in identifying and rectifying errors. Manual code reviews involve developers examining code to detect potential issues, relying on their expertise and experience. While this method can be effective, it is time-consuming and prone to human error, especially as codebases grow larger and more complex. Static analysis tools analyze code without executing it, identifying potential vulnerabilities and coding standard violations. However, static analysis may produce false positives or miss subtle errors, particularly in dynamic or complex code structures. Testing, including unit, integration, and system testing, is essential for verifying code behavior under various conditions. Despite its importance, testing cannot guarantee the absence of all errors, as it is often impractical to test every possible input and execution path.

Formal verification, which involves mathematically proving that a system adheres to its specifications, offers a more rigorous approach to code verification. However, formal verification is resource-intensive and requires specialized knowledge, making it less accessible for many development teams. Additionally, the scalability of formal methods remains a concern, as applying them to large and complex codebases can be challenging. The gap between the ideal of perfect code and the reality of practical software development highlights the limitations of current verification methods and the need for more effective solutions.

The advent of AI and machine learning presents new opportunities and challenges in code verification. While AI has the potential to automate and enhance verification processes, it also introduces complexities, such as ensuring the reliability of AI-generated code and addressing the potential for AI models to learn and propagate errors present in training data. The challenge of verifying AI-generated code underscores the need for robust verification frameworks that can handle the unique characteristics of AI systems.

In summary, the complexities involved in code verification stem from the intricate nature of modern software systems, the limitations of traditional verification methods, and the emerging challenges posed by AI technologies. Addressing these challenges requires the development of more sophisticated, scalable, and accessible verification techniques that can ensure the reliability and security of software in an increasingly complex technological landscape.

The integration of artificial intelligence (AI), particularly large language models (LLMs), into the code verification process represents a significant advancement in software engineering. LLMs, such as OpenAI's GPT series, have demonstrated remarkable capabilities in understanding and generating human-like text, which has been extended to the realm of code generation and verification. These models are being explored to automate various aspects of the verification process, aiming to enhance efficiency, accuracy, and scalability.

One of the primary applications of LLMs in code verification is their ability to generate code snippets based on natural language descriptions. This capability allows developers to specify desired functionalities in plain language, with the LLM translating these specifications into code. While this approach can expedite the development process, it also necessitates rigorous verification to ensure that the generated code aligns with the intended specifications and is free from errors.

To address this challenge, researchers have been developing methods to enhance the reliability of AI-generated code. For instance, the Clover paradigm, introduced by Stanford AI Lab, focuses on closed-loop verifiable code generation. This approach checks consistencies among code, docstrings, and annotations, enforcing correctness in AI-generated code. By ensuring that the generated code, its documentation, and annotations are consistent, Clover aims to improve the trustworthiness of AI-generated code.

Another significant development is the LEVER framework, which learns to verify language-to-code generation through execution. LEVER trains verifiers to determine the correctness of programs based on natural language input, the program itself, and its execution results. By combining verification scores with the LLM generation probability, LEVER enhances the accuracy of code generation, achieving state-of-the-art results across various datasets.

Despite these advancements, challenges remain in ensuring the reliability of AI-generated code. LLMs can sometimes produce code that appears plausible but fails to meet the expected requirements or executes incorrectly—a phenomenon known as "code hallucinations." To address this, researchers have proposed methods to detect and mitigate such hallucinations. For example, the CodeHalu benchmark categorizes code hallucinations into mapping, naming, resource, and logic types, providing a framework to understand and address these issues.

Furthermore, the integration of AI in code verification is not limited to code generation. LLMs are also being utilized to assist in debugging and code optimization. Tools like LDB (Large Language Model Debugger) enable LLMs to refine their generated programs using runtime execution information, facilitating the identification and correction of errors in the code.

The role of AI in code verification is continually evolving, with ongoing research aimed at improving the accuracy, efficiency, and reliability of AI-assisted verification processes. As AI models become more sophisticated, their integration into the software development lifecycle is expected to become more seamless, offering developers powerful tools to ensure the correctness and security of their code.

Evaluation and Results

The evaluation of AI models on the miniCodeProps benchmark employs two primary methodologies: full-proof generation and tactic-by-tactic generation. These approaches are designed to assess the capabilities of AI systems in automating the proof generation process within the Lean proof assistant environment.

In the full-proof generation approach, the AI model is tasked with producing a complete proof for a given program specification. This method involves the model generating one or more potential proofs, which are then verified by the Lean 4 kernel. The verification process checks the validity of each proof, ensuring that it adheres to the logical and syntactical rules of the Lean proof assistant. If any of the generated proofs are valid, the specification is considered successfully proven. This approach allows for a comprehensive evaluation of the AI model's ability to generate complete and correct proofs without incremental guidance. However, it may be computationally intensive, as it requires the model to produce entire proofs in a single generation.

Alternatively, the tactic-by-tactic generation approach involves the AI model suggesting individual proof steps, known as tactics, which are then executed by the Lean 4 kernel. Each tactic modifies the current proof state, and the resulting state is used to prompt the model for the next tactic. This process continues iteratively until the proof is complete or a predefined computational budget is exhausted. This method mirrors the interactive theorem proving process, where human users incrementally build proofs through a series of logical steps. It allows for a more granular assessment of the AI model's reasoning capabilities and its ability to navigate the proof landscape step by step. Additionally, this approach can be more efficient, as it focuses on generating one proof step at a time, potentially reducing the computational resources required compared to full-proof generation.

Both methodologies are evaluated within the context of the miniCodeProps benchmark, which consists of 201 program specifications categorized into three levels of difficulty: easy (Medley), medium (Termination), and hard (Sorting). These categories encompass a range of proof challenges, from straightforward properties of basic data structures to complex properties of nonstandard sorting algorithms. The benchmark provides a standardized framework for assessing the performance of AI models in code verification tasks, facilitating comparisons across different models and approaches.
