However, costs might arise from using associated models like OpenAI or Anthropic. - **Requirements:** Min 2 GB RAM - **Adopt for:** GPTRouter is notable for TypeScript and handles multiple LLMs and image models like OpenAI, Anthropic, Azure, Dall-E, SDXL with improved reliability and speed. - **License detail:** The MIT license applies to GPTRouter, offering permissive use with conditions only requiring preservation of copyright and license notices. ## Choose when ### Choose tiger if… - tiger is primarily Jupyter Notebook; GPTRouter is TypeScript. - License: tiger is Apache-2.0, GPTRouter is MIT. - Tags unique to tiger: ai safety, classification, data-augmentation, fine-tuning. - Also covers Data & Retrieval. - Projects demanding enhanced model safety and reliability in production. ### Choose GPTRouter if… - GPTRouter is primarily TypeScript; tiger is Jupyter Notebook. - License: GPTRouter is MIT, tiger is Apache-2.0. - Pricing: GPTRouter is open-source under the MIT License. However, costs might arise from using associated models like OpenAI or Anthropic.. - Requirements: Min 2 GB RAM. - Tags unique to GPTRouter: anthropic, azure-openai, cohere, google-gemini. - Also covers Inference & Serving. - GPTRouter ships Docker support for self-hosted deployment. - When your project requires seamless integration of different language models such as OpenAI, Anthropic, and Azure and demands reliability and fast response times. ## When NOT to use tiger - For teams needing a comprehensive low-level LLM framework like Hugging Face Transformers due to lack of foundational models support by Tiger. - If priority lies with real-time model deployment automation as opposed to pre-deployment reliability checks and training enhancements. ## When NOT to use GPTRouter - 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. ## Common questions ### What is the difference between tiger and GPTRouter? tiger: Open Source LLM toolkit for trustworthy applications.
