 title: "Generate In-Context Examples"
-description: ""
+description: "If we do not have examples for our task, we can utilize *self-generated* in-context learning (SG-ICL), where we use a model to generate in-context examples."

-How can we generate examples for our prompt?
+How can we generate examples of our task to improve model outputs?
 
-Self-Generated In-Context Learning (SG-ICL) is a technique which uses an LLM to generate examples to be used during the task. This allows for in-context learning, where examples of the task are provided in the prompt.
+In-context learning is a prompting technique where examples are provided in the prompt for the model to learn from at inference time. If we do not already have examples for our task, we can utilize *self-generated* in-context learning (SG-ICL), where we use a model to generate these in-context examples.
 
-We can implement SG-ICL using `instructor` as seen below.
+## Implementation
 
 ```python
 import instructor
-from pydantic import BaseModel
 from openai import OpenAI
-from typing import Literal

-n = 4  # num examples to generate per class

-class GeneratedReview(BaseModel):
-    review: str
-    sentiment: Literal["positive", "negative"]
+class GeneratedExample(BaseModel):
+    input: str
+    output: str
 
 
-class SentimentPrediction(BaseModel):
-    sentiment: Literal["positive", "negative"]
+class Response(BaseModel):
+    output: str
 
 
 client = instructor.from_openai(OpenAI())
