Junie in particular, or just their various other "AI Assistant" / "Chat" things? They have multiple confusing overlapping products/modes going on. "JetBrains AI" -- which may or may not be same as "Junie"?, "AI Chat", then there's the "Agents" tab which integrates outside coding agents.
I guess they iterated quite a few products to "not get behind" and see what sticks.
Most recently they integrated air, which is basically an "agent management/orchestrator" where you can run any ACP-compatible agent with any model you want and it's just the single place where you manage them, see their progress, steer them, merge their results etc.
