## Choose when

### Choose LLM-Agents-Ecosystem-Handbook if…

- LLM-Agents-Ecosystem-Handbook is primarily Python; ReAct is Jupyter Notebook.
- Requirements: Min 2 GB RAM; Requires Python for full functionality.; Suitable for both local development and deployment..
- Tags unique to LLM-Agents-Ecosystem-Handbook: ai-agent, fine-tuning, finetuning-llms, framework.
- Also covers Evaluation & Observability.
- Use this when you need comprehensive guides covering the entire development lifecycle of a language model agent, from setup through deployment.

### Choose ReAct if…

- ReAct is primarily Jupyter Notebook; LLM-Agents-Ecosystem-Handbook is Python.
- Tags unique to ReAct: decision-making, large language models, llm, prompting.
- Also covers LLM Frameworks.
- When aiming for better decision-making in HotpotQA, alfworld environments, or WebShop scenarios with GPT-3

## When NOT to use LLM-Agents-Ecosystem-Handbook

- When you seek only theoretical knowledge without hands-on projects. This repository is heavily focused on practical aspects.
- If your project needs languages other than Python or uses frameworks not discussed here, the LLM-Agents-Ecosystem-Handbook may not be suitable as it concentrates exclusively on Python tools and LLM ecosystems.
- If you're aiming to work with a very niche aspect of LLMs that isn't yet covered by this extensive but still limited set of resources.

## When NOT to use ReAct

- If requiring extensive custom task integration beyond provided notebooks, LangChain's zero-shot ReAct agent may be more preferable
- When PaLM outperforms GPT-3 on specific tasks or if an alternative model is preferred
