Technical Specifications
| Feature | JetBrains AI Assistant | Qodo (formerly Codium) |
|---|---|---|
| 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). | Qodo uses a combination of its own proprietary, fine-tuned models (such as TestGPT and embedding models for code) and allows users to select from leading third-party models, including OpenAI's GPT series, Anthropic's Claude models, and Google's Gemini 2.5 Pro. |
| 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. | Qodo is context-aware, utilizing Retrieval-Augmented Generation (RAG) and a codebase intelligence engine to index and understand an organization's entire codebase across multiple repositories for more accurate and tailored suggestions. |
| 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. | Qodo offers a multi-tenant SaaS solution for its free and team plans. The Enterprise plan provides flexible deployment options, including single-tenant SaaS, a private cloud (VPC), and fully on-premise or 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. | Partially. While most advanced features require an internet connection, some basic functions like code completion can work offline. Full offline capability is available through the on-premise and air-gapped enterprise deployments. |
