Alipay-PIBench: A Realistic Payment Integration Benchmark for Coding Agents

2026-07-16 · Source: Artificial Intelligence · Field: Technology & Digital — Artificial Intelligence & Machine Learning, Software Development & Engineering · Depth: Expert, quick

Summary

Alipay-PIBench is a new benchmark designed to evaluate coding agents on realistic Alipay payment integration tasks, which are complex, repository-level software challenges. This benchmark comprises nine product-specific projects and 18 task instances, categorized into "Basic functional-completion" and "Advanced risk-aware hardening" scenarios. Evaluation relies on scenario-specific rubrics, incorporating deterministic static, unit, integration, and end-to-end checks, augmented by LLM-assisted assessment for semantic requirements. Six coding-agent models were tested, reporting a rubric pass rate (RPR). Under the "with-skill" condition, mean RPRs ranged from 68.58% to 91.37%. Access to the "alipay-payment-integration skill" significantly improved mean RPR by 10.31 percentage points on average, demonstrating the benchmark's utility in diagnosing model capabilities and assessing structured guidance for payment integration.

Key takeaway

For AI Engineers developing or deploying coding agents for financial applications, you should consider evaluating agent performance against realistic, complex benchmarks like Alipay-PIBench. This benchmark highlights the critical need for agents to handle both functional completion and risk-aware hardening scenarios, demonstrating that specialized "skills" can significantly improve integration success rates. Prioritize agents that show robust performance across diverse payment integration challenges.
