[aikit](https://kaito-project.github.io/aikit/) reports 534 GitHub stars, 57 forks, and 43 open issues, last pushed Jul 20, 2026. [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 aikit if… - aikit is primarily Go; GPTRouter is TypeScript. - Tags unique to aikit: ai, buildkit, chatgpt, docker. - - You need a flexible solution specifically built using Go and prefer its concurrency model. ### Choose GPTRouter if… - GPTRouter is primarily TypeScript; aikit is Go. - 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. - 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 aikit - - You have a preference or requirement for Python-based tools due to the lack of native support in Aikit. - - If your deployment setup strictly uses cloud-specific platforms and you do not use Kubernetes or Docker, as Aikit heavily integrates with containerized environments like these. ## 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 aikit and GPTRouter? aikit: Fine-tune, build, and deploy open-source LLMs easily!. GPTRouter: Manage multiple LLMs and image models for reliable and fast responses. See the comparison table for live GitHub stats and shared categories. ### When should I choose aikit over GPTRouter?
