Technical Specifications

Feature JetBrains AI Assistant Tabnine
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). Tabnine uses its own proprietary, private AI models for code completion and chat. It also allows users to switch to third-party models from providers like Anthropic (Claude), OpenAI (GPT), Cohere, and Mistral.
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. Tabnine is context-aware, analyzing your local IDE environment and project files to provide relevant suggestions. The Enterprise plan allows connecting to an organization's entire codebase (GitHub, GitLab, Bitbucket) for more deeply personalized, context-aware recommendations.
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. Tabnine offers flexible deployment. It is available as a secure multi-tenant SaaS for all users. For Enterprise customers, it offers fully private deployments on-premises, in a Virtual Private Cloud (VPC), or in a completely air-gapped environment.
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. Yes, Tabnine's AI can run locally on a developer's machine, on a server behind a firewall, or in the cloud, supporting offline use cases.
