About

GPT-5.2-Codex is OpenAI’s most advanced agentic coding model, built for complex, real-world software engineering and defensive cybersecurity work. It is a specialized version of GPT-5.2 optimized for long-horizon coding tasks such as large refactors, migrations, and feature development. The model maintains full context over extended sessions through native context compaction. GPT-5.2-Codex delivers state-of-the-art performance on benchmarks like SWE-Bench Pro and Terminal-Bench 2.0. It operates reliably across large repositories and native Windows environments. Stronger vision capabilities allow it to interpret screenshots, diagrams, and UI designs during development. GPT-5.2-Codex is designed to be a dependable partner for professional engineering workflows.

About

StackRails is a software architecture and AI coding governance platform for engineering organizations. It builds a live knowledge graph of repositories, services, APIs, events, and cloud infrastructure, then provides coding agents with architecture and policy context through the Model Context Protocol (MCP). It supports Claude Code, GitHub Copilot, Cursor, and OpenAI Codex, and checks generated code against organization-defined rules on developers’ machines and in pull-request workflows. Teams can use it to map cross-repository dependencies, assess change impact, maintain architecture documentation, manage engineering policies, and run AI-assisted architectural reviews. StackRails is available as a hosted EU service, in customer-managed cloud environments on AWS, Microsoft Azure, or Google Cloud, and as an on-premises deployment.
