JetBrains Is Moving Beyond AI Chat, Here’s What Comes Next

AI chat isn’t dead, but for serious coding workflows, agents are taking over. JetBrains AI is moving to an agent-first experience, giving developers a capable coding agent from the moment they start instead of making them begin in chat mode and configure everything themselves. But which agent should be the default? We tested multiple agents on real-world Java, Python, and C# tasks, including bug fixes, feature development, and codebase enhancements. We compared their ability to solve each task while balancing three things developers care about: correctness, speed, and cost. In this video, we break down: Why JetBrains AI is becoming agent-first Why Codex became the recommended default How Codex compared with Junie in our benchmarks and user testing Where Junie may still be the better choice How to switch agents and choose the right setup for your project The benchmarks were closer than you might expect, and the default won’t necessarily be the best option for every developer.
