[OpenPipe](https://openpipe.ai) reports 2.8k GitHub stars, 178 forks, and 8 open issues, last pushed May 25, 2024. [GPTRouter](https://gpt-router.writesonic.com/) has 455 stars, 38 forks, and 10 open issues, last pushed Apr 10, 2024.

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 OpenPipe if… - License: OpenPipe is Apache-2.0, GPTRouter is MIT. - Tags unique to OpenPipe: ai, fine-tuning, llm, model-hosting. - If you need to integrate with OpenAI's SDK in Python or TypeScript easily ### Choose GPTRouter if… - License: GPTRouter is MIT, OpenPipe 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 OpenPipe - Avoid if requiring real-time support or updates as development is currently paused for integration of proprietary code - Not ideal for users needing immediate access to the latest features due to its transition phase ## 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 OpenPipe and GPTRouter?
