Official account of ByteDance SE Lab, sharing research and practical experience in software engineering. Our lab unites researchers and engineers from various domains to accelerate the fusion of software engineering and AI, driving technological progress in every phase of software development.
The article explains how Volcano Engine's TLS provides a zero‑intrusion, one‑click plugin for OpenClaw that automatically collects logs, metrics, and traces, generates cost, operations, performance, and security dashboards, and includes authentication options, installation commands, and a SQL‑based token anomaly investigation.
The article demonstrates how OpenViking adds traceable, incremental memory to multiple agents, allowing VikingBot to record game events, recognize player styles, hold grudges, form alliances, and disguise identities across Werewolf rounds, resulting in a clear win‑rate boost and near‑three‑fold accuracy improvement while maintaining strong multi‑tenant security.
This article analyzes the DisCoGC algorithm introduced by ByteDance, explaining how its discard‑centric garbage collection eliminates the write‑amplification vs. space‑amplification trade‑off in log‑structured storage, details the engineering challenges of multi‑layer deployment, and presents production results showing up to 20% TCO reduction without impacting latency.
The rapid rise of autonomous AI agents like OpenClaw exposes severe security gaps—over‑privileged access, unauthenticated public instances, and one‑click RCE—forcing a rethink of identity‑centric IAM designs that can protect agents through propagation, secretless auth, context awareness, and intent‑aware authorization.
The Scale‑SWE project combines a massive 100k‑sample software engineering dataset with a high‑concurrency sandbox infrastructure and a multi‑agent workflow to dramatically improve code‑agent training, evaluation, and real‑world performance, surpassing existing models on SWE‑bench benchmarks.
This article details how Douyin engineers tackled Android’s limited heap, file‑descriptor, and thread constraints on older phones by expanding ART malloc and region spaces, enlarging FD/FD_SET limits, and implementing a transparent M:N user‑level threading model, achieving significant stability and performance gains.
The article analyzes how malicious prompt injections can hijack OpenClaw agents' decision logic, outlines three core risk categories—intent deviation, workflow hijack, and data leakage—and presents AgentArmor's runtime protection framework that uses intent alignment, control‑flow integrity, and data‑flow confidentiality checks to mitigate these threats.
This guide explains the challenges of multi‑repository code retrieval, presents an experimental evaluation of OpenViking's semantic search, and provides step‑by‑step instructions for installing, configuring, importing repositories, and integrating the system into AI agents and chatbots.
The 2026 Spring Festival Gala showcased a breakthrough spatial video system that creates lifelike 3D digital twins in real time, using a 70‑camera 4D reconstruction pipeline, AI‑enhanced rendering, and seamless integration with broadcast and lighting controls to achieve photorealistic, multi‑person performances.
This article explains why robust Agent Tools are essential for LLM agents, outlines a five‑stage lifecycle with concrete design principles such as type safety, LLM‑friendly interfaces, OpenAPI integration, self‑healing error handling, human‑in‑the‑loop safeguards, and performance optimizations, and demonstrates their impact through retail and fintech case studies.
