When NOT to use GPTRouter
Constraint-first guidance from category fit and live maintenance signals - not marketing copy.
- Avoid using GPTRouter if your project strictly uses Python without the flexibility to adopt TypeScript, as it may hinder seamless integration.
- If your application exclusively focuses on a single LLM or image model provider lacking the need for managing multiple providers, consider alternatives more focused in scope and potentially lighter.
