Chat GPT Online vs New API
Side-by-side comparison · Updated October 2026
| Description | ChatGPT is a flexible, general-purpose AI assistant designed to help with writing, brainstorming, coding, research, file and image analysis, and everyday problem solving. The interface includes a Theme Initialization Script that automatically manages the color scheme based on user preference or system settings, helping create a consistent browsing experience across sessions. When the theme is set to system, ChatGPT switches between light and dark modes to match the device’s preferences. When set to light or dark, it retains that choice across page reloads for a personalized, predictable experience. This theme behavior improves readability, reduces eye strain, and supports a more comfortable, intuitive user experience on the ChatGPT platform. | New API is a self-hosted AI gateway and model-management project maintained in the QuantumNous repository. It brings provider channels, access tokens, model restrictions, usage statistics and cost accounting into one interface. Teams supply their own authorized model-provider access and operate the gateway in their chosen environment. The gateway supports several API formats, including OpenAI-compatible requests, Claude Messages and Google Gemini. Compatibility has boundaries: the README marks Gemini-to-OpenAI conversion as text-only without function calling, and OpenAI-compatible to Responses conversion as in development. Test the exact endpoints, streaming behavior and tool calls your application uses before switching traffic. Routing features include weighted channel selection, automatic retry after failures and user-level model rate limits. The dashboard supports request-based, usage-based and cache-hit cost accounting, with token grouping and model-access controls. These controls can help organize usage, but retries and a common API format do not guarantee uninterrupted service or identical behavior across providers. The current repository license is AGPLv3. Docker Compose is the recommended quick-start path in the README, which also documents Docker commands with SQLite or MySQL. Running the software still involves infrastructure, operations and upstream model charges. Review the current license, secure your deployment and validate accounting against provider bills. Compare LiteLLM if you also want a Python SDK or a documented gateway for MCP servers and agents. |
