First lets define the prompt: ```python -from langchain.prompts import PromptTemplate +from langchain import Prompt -prompt = PromptTemplate( +prompt = Prompt( input_variables=["product"], template="What is a good name for a company that makes {product}?", ) ``` +Next, let's instantiate the LLM (we'll use OpenAI's text-davinci-002 model in this example, with a temperature setting of 0.5. + +```python +from langchain import OpenAI + +llm = OpenAI(model_name="text-davinci-002", temperature=0.5) +``` + We can now create a very simple chain that will take user input, format the prompt with it, and then send it to the LLM: ```python -from langchain.chains import LLMChain +from langchain import LLMChain chain = LLMChain(llm=llm, prompt=prompt) ``` Now we can run that can only specifying the product! ```python -chain.run("colorful socks") +chain.predict("colorful socks") ``` There we go! There's the first chain. -That is it for the Getting Started example. +That is it for the Getting Started example. As a next step, we would suggest checking out the more complex chains in the [Demos section](/examples/demos)
