Jules is Google's asynchronous coding agent, powered by Gemini. Unlike interactive agents, you assign it tasks — bug fixes, dependency bumps, small features — and it clones your repo into a cloud VM, writes and tests the change, and comes back with a pull request and an audio changelog summary. The free tier makes it an easy add to any workflow, but the async model means it suits queued, well-defined tasks rather than tight pair-programming loops, and turnaround depends on task queue and complexity.
Windsurf (formerly Codeium) is an AI-first code editor featuring Cascade — an agentic flow that can handle multi-file, multi-step coding tasks. It combines the familiarity of VS Code with powerful AI capabilities including code generation, refactoring, and terminal integration.
Whichever AI agent you choose, Standard Compute gives you unlimited LLM compute at one flat monthly price. No rate limits, no per-token billing.
