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 MGM if… - MGM is primarily Python; GPTRouter is TypeScript. - License: MGM is Apache-2.0, GPTRouter is MIT. - Tags unique to MGM: additional-packages-training-cases, generation, large language models, multi-modality. - When working on projects requiring integration of text and visual data for generation tasks. ### Choose GPTRouter if… - GPTRouter is primarily TypeScript; MGM is Python. - License: GPTRouter is MIT, MGM 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 MGM - Avoid if your project requires commercial licensing, as MGM is strictly research-use only under CC BY NC 4.0. - Not suitable if you are unable to update or ensure the availability of required Python packages like flash-attn and ninja for training purposes. ## 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 MGM and GPTRouter?
