Summary
Windsurf announced GPT-5.5 availability on April 24, 2026, adding OpenAI's latest model to the editor's multi-model coding-agent stack. The release follows Windsurf 2.0 and extends the same environment that now includes Devin Local, Claude Opus 4.7, and SWE-1.6.
What changed
Windsurf added GPT-5.5 as a selectable model in the editor.
Why it matters
Model choice is becoming a competitive workflow surface for coding tools, not just a backend detail. Adding GPT-5.5 keeps Windsurf current with leading agentic coding models and helps it compete with Cursor, Codex, and Claude Code on frontier-model access inside one product.
