# Glossary
|
||
|
||
This is a collection of terminology commonly used when developing LLM applications.
|
||
It contains reference to external papers or sources where the concept was first introduced,
|
||
as well as to places in LangChain where the concept is used.
|
||
|
||
## Chain of Thought Prompting
|
||
|
||
A prompting technique used to encourage the model to generate a series of intermediate reasoning steps.
|
||
A less formal way to induce this behavior is to include “Let’s think step-by-step” in the prompt.

|
||
## Action Plan Generation
|
||
|
||
A prompt usage that uses a language model to generate actions to take.
|
||
The results of these actions can then be fed back into the language model to generate a subsequent action.

||
## ReAct Prompting
|
||
|
||
A prompting technique that combines Chain-of-Thought prompting with action plan generation.
|
||
This induces the to model to think about what action to take, then take it.

||

|
||
|
||
## Self-ask
|
||
|
||
A prompting method that builds on top of chain-of-thought prompting.
|
||
In this method, the model explicitly asks itself follow-up questions, which are then answered by an external search engine.

|

|
||
## Prompt Chaining
|
||
|
||
Combining multiple LLM calls together, with the output of one-step being the input to the next.

|

||
## Memetic Proxy
|
||
|
||
Encouraging the LLM to respond in a certain way framing the discussion in a context that the model knows of and that will result in that type of response. For example, as a conversation between a student and a teacher.

|
||
|
||
## Self Consistency
|
||
|
||
A decoding strategy that samples a diverse set of reasoning paths and then selects the most consistent answer.
|
||
Is most effective when combined with Chain-of-thought prompting.

|
||
|
||
## Inception
|
||
|
||
Also called “First Person Instruction”.
|
||
Encouraging the model to think a certain way by including the start of the model’s response in the prompt.

## MemPrompt
|
||
|
||
MemPrompt maintains a memory of errors and user feedback, and uses them to prevent repetition of mistakes.
