Getting Started
Before you get your hands dirty, make sure you have a few prerequisites in place:
Your OpenAI API key, which you'll need to access various models.
Basic knowledge of Python (if you're not familiar, don’t worry; examples will guide you).
Step 1: Setting Up Your Environment
Install Required Packages:
First off, you need to install the langchain-openai package. Go ahead and run this in your terminal:
1
2
bash
pip install langchain-openai
Set Your OpenAI API Key:
This is crucial! Set the environment variable for your API key. You can do this in your terminal with:
1
2
3
4
``bash
export OPENAI_API_KEY='your_api_key_here'
````
Make sure to replace
your_api_key_here` with your actual OpenAI API key. (You can also do this within your Python script, but it's usually best practice to keep secrets out of your code.)
Step 2: Instantiating ChatOpenAI
Let's start programming! Open your favorite Python environment and follow these steps:
```python
from langchain_openai import ChatOpenAI
temperature` parameter determines the randomness of the output; a lower value means more control and determinism.
Step 3: Invoking the Model
Toying around with your shiny new setup? It's the right time! Let’s start making it talk. You can invoke the model with messages like below:
```python
messages = [
("system", "You are a helpful assistant that translates English to French."),
("user", "I love programming.")
]
ai_msg = llm.invoke(messages)
print(ai_msg.content)
1
2
``
Your model will respond with its amazing translation powers! You should see:
J'adore la programmation.` That’s the beauty of ChatOpenAI at work!
Advanced Features
Now that you've got the basics, let's explore some advanced features that ChatOpenAI offers:
Tool Calling
Tool calling allows you to describe tools and arguments in your prompts. It helps in generating structured outputs which makes it super useful for applications like chatbots. Here’s how you set it up:
```python
from pydantic import BaseModel, Field
class GetWeather(BaseModel):
"""
Get current weather given location
"""
location: str = Field(..., description="The city state, e.g. San Francisco, CA")
llm_with_tools = llm.bind_tools([GetWeather])
ai_msg = llm_with_tools.invoke("What's the weather in San Francisco?")
print(ai_msg)
```
This neat setup allows your assistant to respond regarding the weather based on your queries. Tool calling makes it resourceful!
Chaining Calls
Want to make more complex interactions? Chaining is your savior!
```python
from langchain.prompts import ChatPromptTemplate
response = chain.invoke({"input_language": "English", "output_language": "German", "input": "I love programming."})
print(response.content)
```
This code will receive a structured response while maintaining the context based on your input.
