# 🤖 Large language models (LLMs)

## 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 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 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 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

              }
          },
          "required": ["question", "answer", "person_who_is_asking"],
      },
  }

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

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

  print(result)
  ```

<Accordion title="Using actual python functions">
  ```python

    return req.json()

  llm = OpenAILlm(config=None,functions=[find_info_of_pokemon])

  result = app.query("Tell me more about the pokemon pikachu.")

  print(result)
  ```
</Accordion>
