Qt's platform is a central hub for developers and UI/UX designers, offering insights into cross-platform application development, graphical user interface (GUI) design, and software development tools. Through articles, tutorials, and documentation, Qt offers insights into building responsive and intuitive applications with Qt framework. Developers can learn about Qt widgets, QML language, and Qt Creator IDE to create modern and visually appealing user interfaces.

Qt AI Assistant 0.9.9 for Qt Creator adds support for three updated LLMs. GPT 5.3-Codex achieves 75% on the QML100 benchmark (up from 64%), making it a viable option again for Qt development. Claude Sonnet 4.6 shows a regression in QML coding performance (64%), with issues around layout sizing and reserved property names. Gemini 3.1 Pro Preview leads the pack at 88% on QML100, offering concise outputs and better token efficiency compared to Anthropic models.
