## Overview

Embedchain comes with built-in support for various popular large language models. We handle the complexity of integrating these models for you, allowing you to easily customize your language model interactions through a user-friendly interface.

## OpenAI

To use OpenAI LLM models, you have to set the `OPENAI_API_KEY` environment variable. You can obtain the OpenAI API key from the [OpenAI Platform](https://platform.openai.com/account/api-keys).

Once you have obtained the key, you can use it like this:

```python
import os
from embedchain import Pipeline as App

os.environ['OPENAI_API_KEY'] = 'xxx'

app = App()
app.add("https://en.wikipedia.org/wiki/OpenAI")
app.query("What is OpenAI?")
```

If you are looking to configure the different parameters of the LLM, you can do so by loading the app using a [yaml config](https://github.com/embedchain/embedchain/blob/main/configs/chroma.yaml) file.

<CodeGroup>

```python main.py
import os
from embedchain import Pipeline as App

os.environ['OPENAI_API_KEY'] = 'xxx'

# load llm configuration from config.yaml file
app = App.from_config(config_path="config.yaml")
```

```yaml config.yaml
llm:
  provider: openai
  config:
    model: 'gpt-3.5-turbo'
    temperature: 0.5
    max_tokens: 1000
    top_p: 1
    stream: false
```
</CodeGroup>

### Function Calling
To enable [function calling](https://platform.openai.com/docs/guides/function-calling) in your application using embedchain and OpenAI, you need to pass functions into `OpenAILlm` class as an array of functions. Here are several ways in which you can achieve that:

Examples:
<Accordion title="Using Pydantic Models">
  ```python
import os
from embedchain import Pipeline as App
from embedchain.llm.openai import OpenAILlm
import requests
from pydantic import BaseModel, Field, ValidationError, field_validator

os.environ["OPENAI_API_KEY"] = "sk-xxx"

class QA(BaseModel):
    """
    A question and answer pair.
    """

    question: str = Field(
        ..., description="The question.", example="What is a mountain?"
    )
    answer: str = Field(
        ..., description="The answer.", example="A mountain is a hill."
    )
    person_who_is_asking: str = Field(
        ..., description="The person who is asking the question.", example="John"
    )

    @field_validator("question")
    def question_must_end_with_a_question_mark(cls, v):
        """
        Validate that the question ends with a question mark.
        """
        if not v.endswith("?"):
            raise ValueError("question must end with a question mark")
        return v

    @field_validator("answer")
    def answer_must_end_with_a_period(cls, v):
        """
        Validate that the answer ends with a period.
        """
        if not v.endswith("."):
            raise ValueError("answer must end with a period")
        return v

llm = OpenAILlm(config=None,functions=[QA])
app = App(llm=llm)

result = app.query("Hey I am Sid. What is a mountain? A mountain is a hill.")

print(result)
  ```
  </Accordion>
  
  <Accordion title="Using OpenAI JSON schema">
```python

</Accordion>

## Google AI

To use Google AI model, you have to set the `GOOGLE_API_KEY` environment variable. You can obtain the Google API key from the [Google Maker Suite](https://makersuite.google.com/app/apikey)

<CodeGroup>
```python main.py

app.add("https://www.forbes.com/profile/elon-musk")

response = app.query("What is the net worth of Elon Musk?")
if app.llm.config.stream: # if stream is enabled, response is a generator
    for chunk in response:
        print(chunk)
else:
    print(response)
