March 2026 DigitalOcean Tutorials: GPT-5.4 and Nemotron 3

AI development continues to change with the consistent release of new models, standards, and system architectures. It can often be a lot to keep track of and learn. But DigitalOcean has you covered with our community tutorials and resources. These 10 tutorials from last month cover both practical, hands-on topics (such as building a game with GPT-5.4) and explanatory concepts (like migrating to multi-agent systems). Take a look and try them out—or bookmark them for some weekend coding! Getting Started with Qwen3.5 Vision-Language Models This tutorial walks through how to run and experiment with Qwen 3.5, an open-source multimodal model family that handles text, images, and even video. It breaks down the model’s architecture and demonstrates how to deploy it on GPU infrastructure so you can build apps like coding assistants or document analyzers on your own stack. You’ll see how high-performing multimodal AI is becoming accessible without relying on proprietary APIs. A2A vs MCP: How The
