· Updated
Windsurf, an AI-native IDE built by Codeium, now includes
GPT-5.4 mini as an available model. According to OpenAI, the model is optimized for coding, computer use, multimodal understanding, and subagent workflows — covering the core capabilities developers rely on in agentic coding sessions. It runs 2x faster than GPT-5 mini, making it a lower-latency option for agentic tasks inside the editor.For developers already using Windsurf's agentic features, the 2x speed gain directly reduces wait times across multi-step workflows. OpenAI's subagent optimization aligns with how coding agents work in practice — generating code, running tests, and iterating across files in a single session, where each step involves a model call.
GPT-5.4 mini is available now in Windsurf's model selector. It's worth testing on longer agentic sessions where latency compounds across multiple sequential model calls.
