About

JetBrains ships AI as IDE-integrated tiers rather than a standalone app: AI Assistant handles completion, chat, and inline transformations; Junie executes multi-step coding tasks autonomously; Grazie handles prose. Mellum, JetBrains' own code model, anchors the stack alongside OpenAI, Anthropic, Google, xAI, and Bedrock models, with BYOK and locally hosted Ollama/LM Studio models supported. The Agent Client Protocol is the differentiator — Claude, Codex, Gemini CLI, and other external agents can run inside JetBrains IDEs through ACP rather than being locked to first-party features. Pricing runs from a free tier to AI Pro ($100/user/year), AI Ultimate ($300), and AI Enterprise ($720), with enterprise on-premises and hybrid options.
