A Two-Staged LLM-Based Framework for CI/CD Failure Detection and Remediation with Industrial Validation

Continuous Integration and Continuous Deployment (CI/CD) pipelines are pivotal to modern software engineering, yet diagnosing and resolving their failures remains a complex and labor-intensive challenge. In this paper, we present LogSage, the first end-to-end LLM-powered framework that performs root cause analysis and solution generation from failed CI/CD pipeline logs. During the root cause analysis stage, LogSage employs a specialized log preprocessing pipeline tailored for LLMs, which extracts critical error logs and eliminates noise to enhance the precision of LLM-driven root cause analysis. In the solution generation stage, LogSage leverages RAG to integrate historical resolution strategies and utilizes tool-calling to deliver actionable, automated fixes. We evaluated the root cause analysis stage using a newly curated open-source dataset, achieving 98\% in precision and 12\% improvement over naively designed LLM-based log analysis baselines, while attaining near-perfect recall. The end-to-end system was rigorously validated in a large-scale industrial CI/CD environment of production quality, processing more than 3,000 executions daily and accumulating more than 1.07 million executions in its first year of deployment, with end-to-end precision exceeding 88\%. These two forms of evaluation confirm that LogSage providing a scalable and practical solution to manage CI/CD pipeline failures in real-world DevOps workflows.

Grasp2Grasp: Vision-Based Dexterous Grasp Translation via Schrodinger Bridges

We propose a new approach to vision-based dexterous grasp translation, which aims to transfer grasp intent across robotic hands with differing morphologies. Given a visual observation of a source hand grasping an object, our goal is to synthesize a functionally equivalent grasp for a target hand without requiring paired demonstrations or hand-specific simulations. We frame this problem as a stochastic transport between grasp distributions using the Schr\"odinger Bridge formalism. Our method learns to map between source and target latent grasp spaces via score and flow matching, conditioned on visual observations. To guide this translation, we introduce physics-informed cost functions that encode alignment in base pose, contact maps, wrench space, and manipulability. Experiments across diverse hand-object pairs demonstrate our approach generates stable, physically grounded grasps with strong generalization. This work enables semantic grasp transfer for heterogeneous manipulators and bridges vision-based grasping with probabilistic generative modeling.
