## Choose when

### Choose litellm if…

- litellm is primarily Python; GPTRouter is TypeScript.
- License: litellm is Other, GPTRouter is MIT.
- Requirements: Min 4 GB RAM; - Requires Python for installation and operation.; - Supports deployment as a standalone application or integrated into larger applications via library calls..
- GPTRouter and LiteLLM both serve as gateways for connecting to various language models (LLMs), offering fallbacks and performance optimizations.
- Tags unique to litellm: rust, bedrock, ai-gateway, openai.
- Also covers Inference & Serving.
- - You require a unified interface to integrate multiple LLM providers (OpenAI, Anthropic, Bedrock, Azure, etc.) using the OpenAI format.

### Choose GPTRouter if…

- GPTRouter is primarily TypeScript; litellm is Python.
- License: GPTRouter is MIT, litellm is Other.
- Pricing: GPTRouter is available under the MIT license, which supports free use and modification for both personal and commercial projects without requiring attribution..
- GPTRouter and LiteLLM both serve as gateways for connecting to various language models (LLMs), offering fallbacks and performance optimizations.
- Tags unique to GPTRouter: mlops, llama-index, cohere, google-gemini.
- Also covers Model Training, LLM Frameworks.
- - When you need flexible management across various AI models to ensure non-stop service without being dependent on just one model.
- If your application requires handling latency issues effectively,GP

## When NOT to use litellm

- - If your application only needs to integrate with a single LLM provider that does not require the OpenAI standard interface.
- - Your project prioritizes proprietary or closed-source solutions; LiteLLM is open source and may lack some commercial support or enterprise-grade add-ons available in paid alternatives.

## When NOT to use GPTRouter

- - When the requirement is to use only one specific AI model for all requests and not switching models.
- If you need streaming capabilities specifically with Image Models, as GPTRouter currently does
