Technical Specifications
| Feature | Claude Code | JetBrains AI Assistant |
|---|---|---|
| Core AI Model(s) | Claude Code utilizes the Claude Opus 4, Claude Sonnet 4, and Claude Haiku 3.5 models. | JetBrains AI Assistant uses a combination of models. It leverages its own proprietary LLM, Mellum, which is optimized for coding. It also provides access to third-party cloud models from providers like OpenAI, Google (Gemini 2.5 Pro), and Anthropic (Claude 3.7 Sonnet). |
| Context Window | Claude Code features deep codebase awareness, using agentic search to understand entire project structures, including million-line codebases, without requiring manual file selection. | The assistant is deeply integrated into the IDE and is context-aware, using information from the current project, including language versions, libraries, and related files, to generate more accurate prompts and suggestions. |
| Deployment Options | Claude Code is a command-line tool installed via npm that runs in the user's terminal. It integrates with VS Code and JetBrains IDEs and can be run in automated workflows using GitHub Actions. For enterprise use, it can be hosted on AWS Bedrock or Google Cloud Vertex AI. | The AI Assistant is available as a plugin within JetBrains' commercial IDEs. For enterprise customers with strict data privacy needs, an on-premises solution is available through IDE Services, which can run in an air-gapped environment using local models like Llama 3.1 via Hugging Face. |
| Offline Mode | No, Claude Code is a cloud-based tool that requires an internet connection to communicate with Anthropic's APIs and does not have an offline mode. | Yes, JetBrains AI Assistant supports an offline mode. Users can connect to locally hosted models through tools like Ollama or LM Studio, allowing most AI features to function without an internet connection. However, some advanced features like multi-file edits are not available in offline mode. |
