# LlamaIndex Llms Integration: Perplexity
## Installation
To install the required packages, run:
```bash
%pip install llama-index-llms-perplexity
!pip install llama-index
```
## Setup
### Import Libraries and Configure API Key
Import the necessary libraries and set your Perplexity API key:
```python
from llama_index.llms.perplexity import Perplexity
pplx_api_key = "your-perplexity-api-key" # Replace with your actual API key
```
### Initialize the Perplexity LLM
Create an instance of the Perplexity LLM with your API key and desired model settings:
```python
llm = Perplexity(
api_key=pplx_api_key, model="mistral-7b-instruct", temperature=0.5
)
```
## Chat Example
### Sending a Chat Message
You can send a chat message using the `chat` method. Here’s how to do that:
```python
from llama_index.core.llms import ChatMessage
messages_dict = [
{"role": "system", "content": "Be precise and concise."},
{"role": "user", "content": "Tell me 5 sentences about Perplexity."},
]
messages = [ChatMessage(**msg) for msg in messages_dict]
# Get response from the model
response = llm.chat(messages)
print(response)
```
### Async Chat
To send messages asynchronously, you can use the `achat` method:
```python
response = await llm.achat(messages)
print(response)
```
### Stream Chat
For streaming responses, you can use the `stream_chat` method:
```python
resp = llm.stream_chat(messages)
for r in resp:
print(r.delta, end="")
```
### Async Stream Chat
To stream responses asynchronously, use the `astream_chat` method:
```python
resp = await llm.astream_chat(messages)
async for delta in resp:
print(delta.delta, end="")
```
