Recent progress in large -language models (LLMS) have made the development of AI -based coding agents that can generate, modify and understand the software code. However, the evaluation of these systems remains limited, often limited to synthetic or closely worn references, mainly in Python. These benchmarks rarely reflect the structural and semantic diversity of the basic code of the real world and, therefore, many agents surfigment the specific models to the reference rather than demonstrate robust and transferable capacities.
AWS presents Swe-Polybench: a more complete evaluation framework
To meet these challenges, Aws Ai Labs introduced Swe-PolybenchA multilingual reference at the level of the repository designed for the evaluation based on the execution of AI coding agents. Benchmark extends over GitHub standards in four widely used programming languages - Java, JavaScript, Typescript and Python – 2110 Tasks that include bug corrections, functionality implementations and code refactor.
Unlike previous benchmarks, SWE-Polybench incorporates real traction requests (PRS) which close the real problems and include associated test cases, allowing an verifiable assessment. A smaller and laminate subset –Swe-Polybench500– was also published to support faster experimentation while preserving the diversity of tasks and languages.
Technical structure and evaluation measures
Swe-Polybench adopts an execution-based evaluation pipeline. Each task includes an instantaneous benchmark and a problem problem derived from a github problem. The system applies the Truth Patch on the ground associated in a containerized test environment configured for the ecosystem of respective language (for example, Maven for Java, NPM for JS / TS, etc.). The reference then measures the results using two types of unit tests: Passage failure (F2P) And passage to passage (P2P).
To provide a more granular evaluation of coding agents, Swe-Polybench present Concrete syntax (CST)– Metrics based. These include recovery scores at the file level and the node level, assessing the agent's capacity to locate and modify the relevant sections of the code base. These measures provide information beyond binary / failure results, in particular for complex and multi-fichiers changes.
Empirical assessment and observations
Three open source coding agents –Assistant,, Sweet-agentAnd Agency– was suitable for Swe-Polybench. All used Claude 3.5 of Anthropic as an underlying model and have been modified to manage multilingual requirements at the reference standard.
The evaluation has revealed notable differences in performance between languages and types of tasks. For example, the agents worked better on Python tasks (up to 24.1% success rate) but fought with typing (as low as 4.7%). Java, despite its higher complexity in terms of changes in average nodes, has reached higher success rates than typing, which suggests that exposure to pre-training and familiarity of syntax play an essential role in the performance of the model.
Performance also varied depending on the complexity of tasks. The tasks limited to functional or a single class changes have given higher success rates (up to 40%), while those requiring mixed or multi-spinning changes have experienced a significant drop. Interestingly, a high precision and recovery reminder – in particular for the identification of files and the CST node – do not always result in higher success rates, which indicates that the location of the code is necessary but insufficient for the solving problems.
Conclusion: towards a solid assessment of AI coding agents
Swe-Polybench presents a robust and nuanced assessment framework for coding agents, addressing the limits of keys in existing benchmarks. By taking charge of several programming languages, covering a wider range of types of tasks and incorporating conscious syntax measures, it offers a more representative assessment of the actual world's applicability of an agent.
The reference reveals that if AI agents have promising capacities, their performance remains incoherent between languages and tasks. Swe-Polybench provides a base for future research aimed at improving the generalization, robustness and reasoning capacities of AI coding assistants.
