Technical Specifications
| Feature | Windsurf | Qodo (formerly Codium) |
|---|---|---|
| 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. | 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 | Supports large context windows via OpenAI's frontier models. Cascade agent maintains multi-file context for complex refactoring tasks. | 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 | Desktop application for macOS, Windows, and Linux. Enterprise plans available with SSO and team management features. | 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 | Limited offline capabilities; core AI features require cloud connectivity to OpenAI's infrastructure. | 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. |
