## 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">

}

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

</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

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

Once you have the key, load the app using the config yaml file:

<CodeGroup>

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

os.environ["JINACHAT_API_KEY"] = "xxx"
# load llm configuration from config.yaml file
app = App.from_config(config_path="config.yaml")
```

```yaml config.yaml
llm:
  provider: jina
  config:
    temperature: 0.5
    max_tokens: 1000
    top_p: 1
    stream: false
```
</CodeGroup>


## Hugging Face


Install related dependencies using the following command:

```bash
pip install --upgrade 'embedchain[huggingface-hub]'
```

First, set `HUGGINGFACE_ACCESS_TOKEN` in environment variable which you can obtain from [their platform](https://huggingface.co/settings/tokens).

Once you have the token, load the app using the config yaml file:

<CodeGroup>

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

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

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

```yaml config.yaml
llm:
  provider: huggingface
  config:
    model: 'google/flan-t5-xxl'
    temperature: 0.5
    max_tokens: 1000
    top_p: 0.5
    stream: false
```
</CodeGroup>

### Custom Endpoints


You can also use [Hugging Face Inference Endpoints](https://huggingface.co/docs/inference-endpoints/index#-inference-endpoints) to access custom endpoints. First, set the `HUGGINGFACE_ACCESS_TOKEN` as above.

Then, load the app using the config yaml file:

<CodeGroup>

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

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

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

```yaml config.yaml
llm:
  provider: huggingface
  config:
    endpoint: https://api-inference.huggingface.co/models/gpt2 # replace with your personal endpoint
```
</CodeGroup>

If your endpoint requires additional parameters, you can pass them in the `model_kwargs` field:

```
llm:
  provider: huggingface
  config:
    endpoint: <YOUR_ENDPOINT_URL_HERE>
    model_kwargs:
      max_new_tokens: 100
      temperature: 0.5
```

Currently only supports `text-generation` and `text2text-generation` for now [[ref](https://api.python.langchain.com/en/latest/llms/langchain_community.llms.huggingface_endpoint.HuggingFaceEndpoint.html?highlight=huggingfaceendpoint#)].

See langchain's [hugging face endpoint](https://python.langchain.com/docs/integrations/chat/huggingface#huggingfaceendpoint) for more information. 

## Llama2

Llama2 is integrated through [Replicate](https://replicate.com/).  Set `REPLICATE_API_TOKEN` in environment variable which you can obtain from [their platform](https://replicate.com/account/api-tokens).

Once you have the token, load the app using the config yaml file:

<CodeGroup>

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

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

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

```yaml config.yaml
