The Subagent Era Is Officially Here - Learn this Now

OpenAI just released GPT-5.4 mini and nano - and they didn't just bill them as cheap models. They explicitly framed them as models built for the subagent era. That's a signal worth paying attention to! Because it's not just OpenAI. Every major coding agent - Claude Code, Codex, Cursor, Gemini CLI, VS Code Copilot, Mistral Vibe, Goose - is doubling down on subagents as a core part of how serious AI workflows get structured. The entire industry is converging on an architecture. This video breaks down what subagents actually are, why they solve the context window problem in a bigger way than you would think, and what this industry shift means for how you build agentic workflows. ~~~~~~~~~~~~~~~~~~~~~~~~~~ - Try Oracle Database 26AI and build AI apps right where your data lives: https://fandf.co/4sDnV9h - Here is my Agentic RAG agent notebook: https://github.com/oracle-devrel/oracle-ai-developer-hub/blob/main/notebooks/oracle_agentic_rag_hybrid_search.ipynb ~~~~~~~~~~~~~~~~~~~~~~~~~~ - Want a complete AI transformation?
