## Decision facts: Prompt-Engineering-Guide

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

## Choose when

### Choose Prompt-Engineering-Guide if…

- Prompt-Engineering-Guide is primarily MDX; speech-to-speech is Python.
- License: Prompt-Engineering-Guide is MIT, speech-to-speech is Apache-2.0.
- Tags unique to Prompt-Engineering-Guide: llms, deep-learning, agents, generative-ai.
- When you seek comprehensive documentation and educational materials specifically focused on the nuance of prompt engineering techniques.

### Choose speech-to-speech if…

- speech-to-speech is primarily Python; Prompt-Engineering-Guide is MDX.
- License: speech-to-speech is Apache-2.0, Prompt-Engineering-Guide is MIT.
- Tags unique to speech-to-speech: assistant, ai, machine-learning, speech.
- Also covers Speech & Audio.
- speech-to-speech ships Docker support for self-hosted deployment.

## 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.

## When NOT to use speech-to-speech

- 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.
