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. LangChain Example
Self-ask
Explicitly have question text generated and use an external search engine
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.

Socratic Models
Memetic Proxy
Make them behave in a specific context by having them play a role.
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.
