## 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
Embedchain supports OpenAI [Function calling](https://platform.openai.com/docs/guides/function-calling) with a single function. It accepts inputs in accordance with the [Langchain interface](https://python.langchain.com/docs/modules/model_io/chat/function_calling#legacy-args-functions-and-function_call).

<Accordion title="Pydantic Model">
  ```python
  from pydantic import BaseModel

  class multiply(BaseModel):
      """Multiply two integers together."""

      a: int = Field(..., description="First integer")
      b: int = Field(..., description="Second integer")
  ```
</Accordion>
  
<Accordion title="Python function">
  ```python
  def multiply(a: int, b: int) -> int:
      """Multiply two integers together.

      Args:
          a: First integer
          b: Second integer
      """
      return a * b
  ```
</Accordion>
<Accordion title="OpenAI tool dictionary">
  ```python
  multiply = {
    "type": "function",
    "function": {
      "name": "multiply",
      "description": "Multiply two integers together.",
      "parameters": {
        "type": "object",
        "properties": {
          "a": {
            "description": "First integer",
            "type": "integer"
          },
          "b": {
            "description": "Second integer",
            "type": "integer"
          }
        },
        "required": [
          "a",
          "b"
        ]
      }
    }
  }
  ```
</Accordion>

With any of the previous inputs, the OpenAI LLM can be queried to provide the appropriate arguments for the function.

```python
import os
from embedchain import App
from embedchain.llm.openai import OpenAILlm

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

llm = OpenAILlm(tools=multiply)
app = App(llm=llm)

result = app.query("What is the result of 125 multiplied by fifteen?")
```

## 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

from embedchain import App

os.environ["GOOGLE_API_KEY"] = "xxx"

app = App.from_config(config_path="config.yaml")

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)
```

```yaml config.yaml
llm:
  provider: google
  config:
    model: gemini-pro
    max_tokens: 1000
    temperature: 0.5
