## Choose when

### Choose AI-Infra-from-Zero-to-Hero if…

- License: AI-Infra-from-Zero-to-Hero is MIT, semantic-router is Apache-2.0.
- Tags unique to AI-Infra-from-Zero-to-Hero: ai-infra, genai, large language models, llmsys.
- Also covers Developer Tools, Model Training.
- When you are aiming to understand the foundational research papers, industry practices, video tutorials specific to ML systems and LLM infrastructures without requiring implementation details.

### Choose semantic-router if…

- License: semantic-router is Apache-2.0, AI-Infra-from-Zero-to-Hero is MIT.
- Pricing: Open-source under Apache-2.0 license, enabling free usage and modification with no cost for the core service..
- Requirements: Min 2 GB RAM; Requires Docker; Requires Go runtime and Docker setup, suitable environments include Kubernetes clusters..
- Tags unique to semantic-router: ai-gateway, bert-classification, fine-tuning, golang.
- - Semantic-Router is ideal when you need an intelligent system to manage a mixture of AI models in different deployment contexts like edge, data center, or cloud.

## When NOT to use AI-Infra-from-Zero-to-Hero

- If you need step-by-step implementations for AI infrastructure setup as the repository focuses on resources rather than detailed technical instructions.
- Avoid if seeking guidance specifically for real-time system deployment and tuning, since it does not cover operational tactics in depth.

## When NOT to use semantic-router

- - Avoid Semantic-Router if your organization strictly uses languages other than Go since the system is language-specific, which might complicate integration.
- - For projects that do not require cross-environment deployment capabilities (such as those exclusively running on cloud infrastructure), Semantic-Router may introduce unnecessary complexity.
