Also supports connections to completely FREE providers like Kiro AI and OpenCode Free without any sign-up or on - **Adopt for:** 9router is a gateway service that connects multiple coding AI agents with free providers, providing token savings through RTK and offering unlimited free access to certain AI models. ## Decision facts: openpi - **Adopt for:** openpi is a specialized tool for model training, inference & serving that leverages advanced GPU capabilities and has specific requirements for memory and hardware configurations. ## Choose when ### Choose 9router if… - 9router is primarily JavaScript; openpi is Python. - License: 9router is MIT, openpi is Apache-2.0. - Pricing: Offers a 'TOKEN SAVER' tier with built-in RTK for FREE, which saves up to 40% on tokens. Also supports connections to completely FREE providers like Kiro AI and OpenCode Free without any sign-up or on. - Tags unique to 9router: ai-agents, free-ai, openai-proxy, token-saver. - Also covers AI Agents. - 9router ships Docker support for self-hosted deployment. - Use when you need to connect to various coding AI agents like Claude Code, Codex, Cursor, Cline, Copilot, and others via a unified gateway. ### Choose openpi if… - openpi is primarily Python; 9router is JavaScript. - License: openpi is Apache-2.0, 9router is MIT. - Tags unique to openpi: fine-tuning, lora, model parallelism, nvidia gpu. - Also covers Model Training. - When you have an NVIDIA GPU with at least 8 GB of VRAM for inference or at least 22.5 GB to fine-tune models using LoRA (Low-Rank Adaptation) on a single GPU. ## When NOT to use 9router - Not suitable if you specifically need advanced or high-priority services from premium providers like Claude Code Pro/Max or Codex Plus/Pro, which offer dedicated support and higher limits. - Avoid using this tool if your coding requirements exceed the capabilities of free models connected via 9router's gateway service. ## When NOT to use openpi - When your project is not compatible with Ubuntu 22.04 or if you do not have access to a supported GPU configuration. - If you need to support multi-node training, as this capability has yet to be implemented in the current version of openpi. ## Common questions ### What is the difference between 9router and openpi? 9router: Unlimited FREE AI coding with auto-fallback and token savings. openpi: Repository for running AI models with GPU requirements specified..
