Technical Specifications
| Feature | Windsurf | Tabnine |
|---|---|---|
| Core AI Model(s) | Primarily powered by OpenAI models (GPT-4.1, o3) with the Cascade agent for agentic workflows. Legacy Codeium models may still be used for low-latency autocomplete. | 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 | Supports large context windows via OpenAI's frontier models. Cascade agent maintains multi-file context for complex refactoring tasks. | 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 | Desktop application for macOS, Windows, and Linux. Enterprise plans available with SSO and team management features. | 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 | Limited offline capabilities; core AI features require cloud connectivity to OpenAI's infrastructure. | 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. |
