Comparison
ai-gateway vs GPTRouter
Verdict
Pick ai-gateway if ai-gateway from Ferro Labs supports over 30 LLMs with integrated caching, guardrails, A/B testing, and cost controls, making it ideal for managing multiple language models in a production environment; pick GPTRouter if gPTRouter is notable for TypeScript and handles multiple LLMs and image models like OpenAI, Anthropic, Azure, Dall-E, SDXL with improved reliability and speed.

Choose ai-gateway if…
- ai-gateway is primarily Go; GPTRouter is TypeScript.
- License: ai-gateway is Apache-2.0, GPTRouter is MIT.
- Tags unique to ai-gateway: ai-gateway, litellm, llm-cost, llm-proxy.
- When you need to integrate more than 30 different LLM services including OpenAI and Anthropic
When NOT to use ai-gateway
- If your project only involves one or two LLMs which does not necessitate the gateway's broad compatibility features
- For small-scale projects that do not require comprehensive cost analysis tools
- When custom integration for specific guardrails is required, as ai-gateway offers generalized settings
Choose GPTRouter if…
- GPTRouter is primarily TypeScript; ai-gateway is Go.
- License: GPTRouter is MIT, ai-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.
- 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 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.
