It depends on the task. Autonomous agents like Devin and OpenAI Codex take on whole tickets, Claude Code works agentically in the terminal, Replit offers a cloud IDE with agents, and Warp adds AI to the terminal. The Vercel AI SDK helps you build AI into your own apps.
An AI software engineer is an agent that plans and completes coding tasks end to end, writing, running, and debugging code with limited supervision. Cognition's Devin and OpenAI Codex are examples. They handle well-scoped work, while humans review output and own architecture and judgment.
It can scaffold and implement substantial parts, and agentic tools make multi-file changes across a project. Cloud environments like Replit let an agent build and run code in one place. Humans still design the system, review logic, and handle the hard or ambiguous parts.
An AI terminal adds natural-language help to the command line, suggesting commands, explaining errors, and automating sequences. Warp is a leading example. It lowers the barrier to complex shell work and speeds up routine tasks without leaving the terminal.
Use a toolkit that handles model calls, streaming, and tools so you focus on product logic. The Vercel AI SDK is a common choice for web apps, and model gateways simplify switching providers. Start with a hosted model, then optimize cost and latency as usage grows.
They are reliable on well-scoped, common tasks and less so on novel or ambiguous ones. Agents like Devin and Codex work best with clear requirements, tests, and review. Treat their output as a strong draft that a developer verifies, not finished, unchecked code.
