Technical Specifications
| Feature | ChatGPT | Qodo (formerly Codium) |
|---|---|---|
| Core AI Model(s) | 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. | 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 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). | 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 | 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. | 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 | 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. | 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. |
