GPT-5.1 and GPT-5.1-Codex are now available in Windsurf.
GPT-5.1 and GPT-5.1-Codex deliver a solid upgrade from GPT-5 for agentic coding workflows. They're noticeably better at understanding what you're asking for and working with you to get it done.
The new variable thinking feature dynamically adjusts reasoning depth—providing quick responses for simple tasks and more thoughtful analysis when complexity demands it.
Priority processing support for GPT-5.1 models, providing guaranteed low-latency responses for faster (~50 tokens/sec), more reliable AI assistance.
Priority processing costs 2x the standard rate, which will be reflected in the Windsurf credit system.
