Sea's View on the Future of Agentic Software Development with Codex

Sea Limited is rolling out Codex, an AI tool for software development, across its engineering teams, with 87% of users actively using it weekly. Unlike simple autocomplete features, Codex provides deep understanding of large codebases (complex collections of code), helping developers navigate dependencies and legacy code while shifting their focus to higher-level design tasks. The company is moving toward agentic workflows (AI systems that can autonomously plan and execute tasks), where AI agents operate within CI/CD pipelines (automated systems that test and deploy code) to reason through requirements, generate tests, and reduce technical debt.
