The verdict
Pick GPT-5.5 if…
- →you want our editor's pick for this category
- →your primary use case is developers and teams needing a frontier reasoning model for agentic coding workflows and large-codebase context handling.
Pick Windsurf if…
- →budget is the constraint
- →your primary use case is developers who want an ai ide that autonomously plans, codes, tests, and iterates across a project with minimal input.
