## Decision facts: Prompt-Engineering-Guide

- **Adopt for:** Decision-critical facts for Prompt-Engineering-Guide

## Choose when

### Choose LLM-RL-Visualized if…

- LLM-RL-Visualized is primarily Python; Prompt-Engineering-Guide is MDX.
- License: LLM-RL-Visualized is Other, Prompt-Engineering-Guide is MIT.
- Tags unique to LLM-RL-Visualized: reinforcement-learning, llm, ai, algorithm.
- Also covers Vector Databases.

### Choose Prompt-Engineering-Guide if…

- Prompt-Engineering-Guide is primarily MDX; LLM-RL-Visualized is Python.
- License: Prompt-Engineering-Guide is MIT, LLM-RL-Visualized is Other.
- Tags unique to Prompt-Engineering-Guide: llms, agents, generative-ai, chatgpt.
- When you seek comprehensive documentation and educational materials specifically focused on the nuance of prompt engineering techniques.

## When NOT to use LLM-RL-Visualized

- LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves.
- AI Agents: Don't use an agent loop when a deterministic workflow would do; agents add latency, cost, and non-determinism.
- Vector Databases: Don't reach for a dedicated vector DB under ~100k vectors; pgvector on your existing Postgres is simpler to operate.

## When NOT to use Prompt-Engineering-Guide

- Avoid using if your focus is entirely on deep-learning frameworks without a need for detailed instructions or examples related to prompt crafting.
- Not suitable when you require tools that go beyond guiding materials, such as custom prompts or direct software plugins provided by competitors focused more on practical implementation over learning.
