Latest developments in massive language fashions (LLMs) have enabled the event of AI-based coding brokers that may generate, modify, and perceive software program code. Nonetheless, the analysis of those techniques stays restricted, typically constrained to artificial or narrowly scoped benchmarks, primarily in Python. These benchmarks seldom replicate the structural and semantic variety of real-world codebases, and because of this, many brokers overfit to benchmark-specific patterns slightly than demonstrating sturdy, transferable capabilities.
AWS Introduces SWE-PolyBench: A Extra Complete Analysis Framework
To deal with these challenges, AWS AI Labs has launched SWE-PolyBench, a multilingual, repository-level benchmark designed for execution-based analysis of AI coding brokers. The benchmark spans 21 GitHub repositories throughout 4 widely-used programming languages—Java, JavaScript, TypeScript, and Python—comprising 2,110 duties that embody bug fixes, function implementations, and code refactorings.
Not like prior benchmarks, SWE-PolyBench incorporates actual pull requests (PRs) that shut precise points and embody related check instances, permitting for verifiable analysis. A smaller, stratified subset—SWE-PolyBench500—has additionally been launched to help faster experimentation whereas preserving job and language variety.
Technical Construction and Analysis Metrics
SWE-PolyBench adopts an execution-based analysis pipeline. Every job features a repository snapshot and an issue assertion derived from a GitHub subject. The system applies the related floor reality patch in a containerized check atmosphere configured for the respective language ecosystem (e.g., Maven for Java, npm for JS/TS, and so forth.). The benchmark then measures outcomes utilizing two sorts of unit assessments: fail-to-pass (F2P) and pass-to-pass (P2P).
To offer a extra granular evaluation of coding brokers, SWE-PolyBench introduces Concrete Syntax Tree (CST)-based metrics. These embody each file-level and node-level retrieval scores, assessing the agent’s skill to find and modify related sections of the codebase. These metrics supply insights past binary move/fail outcomes, particularly for complicated, multi-file modifications.
Empirical Analysis and Observations
Three open-source coding brokers—Aider, SWE-Agent, and Agentless—had been tailored for SWE-PolyBench. All used Anthropic’s Claude 3.5 because the underlying mannequin and had been modified to deal with the multilingual, repository-level necessities of the benchmark.
The analysis revealed notable variations in efficiency throughout languages and job sorts. As an example, brokers carried out finest on Python duties (as much as 24.1% move charge) however struggled with TypeScript (as little as 4.7%). Java, regardless of its greater complexity by way of common node modifications, achieved greater success charges than TypeScript, suggesting that pretraining publicity and syntax familiarity play a essential function in mannequin efficiency.
Efficiency additionally various with job complexity. Duties restricted to single-function or single-class modifications yielded greater success charges (as much as 40%), whereas these requiring blended or multi-file modifications noticed a major drop. Curiously, excessive retrieval precision and recall—significantly for file and CST node identification—didn’t all the time translate to greater move charges, indicating that code localization is important however inadequate for drawback decision.
Conclusion: Towards Sturdy Analysis of AI Coding Brokers
SWE-PolyBench presents a strong and nuanced analysis framework for coding brokers, addressing key limitations in present benchmarks. By supporting a number of programming languages, masking a wider vary of job sorts, and incorporating syntax-aware metrics, it affords a extra consultant evaluation of an agent’s real-world applicability.
The benchmark reveals that whereas AI brokers exhibit promising capabilities, their efficiency stays inconsistent throughout languages and duties. SWE-PolyBench supplies a basis for future analysis aimed toward bettering the generalizability, robustness, and reasoning capabilities of AI coding assistants.
