Technical Specifications
| Feature | JetBrains AI Assistant | Gemini |
|---|---|---|
| Core AI Model(s) | 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). | Gemini is a family of multimodal models developed by Google DeepMind, including Gemini 2.5 Pro, Gemini 2.5 Flash, Gemini 2.0, and Gemini Nano. |
| Context Window | 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. | The context window varies by model. For instance, Gemini 1.5 Pro supports a context window of up to 2 million tokens. |
| Deployment Options | 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. | Gemini is primarily a cloud-based service available via its web interface and the Gemini API. An on-premises solution is becoming available through Google Distributed Cloud (GDC), which allows organizations to run Gemini models in their own data centers, including in air-gapped environments. |
| 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. | No, Gemini is a cloud-based service and requires an internet connection. The on-premise GDC deployment still requires the managed hardware solution and is not a standalone offline application. |
