## Decision facts: llm-twin-course

- **Adopt for:** Provides a comprehensive, free course on building production-ready LLM & RAG systems, including 12 hands-on lessons.

## Decision facts: LLM-Engineers-Handbook

- **Pricing:** freemium - The repository itself is free under the MIT license; however, AWS services (like SageMaker and ECR) require paid usage based on your consumption.
- **Requirements:** Min 8 GB RAM; Requires Docker; - Requires Docker for managing local infrastructure.; - Python version 3.11 is required; Poetry should already be installed to manage dependencies.
- **Adopt for:** A comprehensive guide for deploying advanced LLM and RAG apps on AWS using LLMOps best practices.

## Choose when

### Choose llm-twin-course if…

- Tags unique to llm-twin-course: bytewax, comet-ml, docker, infra-as-code.
- Also covers Data & Retrieval.
- When seeking an extensive guide with practical implementation for setting up LLM and RAG systems using industry best practices.

### Choose LLM-Engineers-Handbook if…

- Pricing: The repository itself is free under the MIT license; however, AWS services (like SageMaker and ECR) require paid usage based on your consumption..
- Requirements: Min 8 GB RAM; Requires Docker; - Requires Docker for managing local infrastructure.; - Python version 3.11 is required; Poetry should already be installed to manage dependencies..
- Tags unique to LLM-Engineers-Handbook: fine-tuning-llm, genai, llm-evaluation, ml-system-design.
- Also covers Developer Tools, Inference & Serving.
- - You are an engineer looking to deploy large language models (LLMs) or retrieval-augmented generation (RAG) applications specifically in an AWS environment.

## When NOT to use llm-twin-course

- Avoid if you're looking for cost-free development, as it requires use of paid APIs from services like OpenAI and AWS.
- Not suitable if your primary goal is to learn theory only, as this repository emphasizes hands-on lessons over in-depth theoretical explanations.

## When NOT to use LLM-Engineers-Handbook

- - If your project is not hosted on AWS, as this tool heavily integrates with AWS services like SageMaker, ECR, and S3, making it less suitable for non-AWS cloud providers.
- - You do not want to manage dependencies via Poetry. The guide assumes you are comfortable working within a Poetry-managed environment.
