Technical Specifications
| Feature | JetBrains AI Assistant | ChatGPT |
|---|---|---|
| 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). | ChatGPT utilizes a range of OpenAI's models, including the GPT-4 series (GPT-4o, GPT-4.1) and the o-series for reasoning (o1, o3, o4-mini). The specific model used can vary based on the user's subscription plan (Free, Plus, Pro, Enterprise) and the selected mode. |
| 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 significantly by model and subscription tier. API and Enterprise users can access up to a 128k or 200k token context window with models like GPT-4o and o3. However, for users of the standard ChatGPT Plus web interface, the effective context window is often smaller (around 32k tokens), with larger documents being handled via Retrieval-Augmented Generation (RAG). |
| 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. | ChatGPT is primarily a cloud-based SaaS application. While a full on-premise deployment of ChatGPT is not offered, businesses can use the OpenAI API to integrate the models into their own applications. For enterprises with strict privacy needs, solutions like Azure OpenAI or third-party platforms enable private cloud or on-premise knowledge stores that can connect to OpenAI's models. |
| 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, ChatGPT requires a constant internet connection to function as it is a cloud-based service. There are open-source, third-party applications that allow users to run different, smaller language models offline, but these are not the official ChatGPT models. |
