[gateway](https://www.missing.studio) reports 160 GitHub stars, 17 forks, and 10 open issues, last pushed Apr 8, 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 gateway if… - gateway is primarily Go; GPTRouter is TypeScript. - License: gateway is Apache-2.0, GPTRouter is MIT. - Tags unique to gateway: ai-gateway, grpc, inference, production-ready. - Use when you need to deploy applications that require low-latency communication like gRPC services. ### Choose GPTRouter if… - GPTRouter is primarily TypeScript; gateway is Go. - License: GPTRouter is MIT, gateway 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 LLM Frameworks. - 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 gateway - Avoid if the project does not involve production-grade AI application deployment or specific needs of grpc and protobuf technologies. - Not suitable for teams preferring other programming languages over Go, as this tool is written entirely in Go. ## 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 gateway and GPTRouter? gateway: Core infrastructure stack for building production-ready AI Applications.
