Apple's Xcode 27 adds native support for Google Gemini, joining existing integrations with Anthropic's Claude and OpenAI's Codex. The update also introduces improved interfaces, interactive planning, and multiturn Q&A capabilities for AI-assisted development.

OpenAI released GPT-5.5 on April 23, 2026, seven weeks after GPT-5.4. The model features a 400K context window in Codex and claims improvements in multi-step tasks, agentic coding, and computer use, though at higher pricing than its predecessor.
