# Key features

* **Advanced Intelligent Routing:** Utilize the power of GPT-4, Claude, and other leading LLMs with our advanced scoring functionality. Pulze.ai’s unique algorithm rates responses based on relevance, accuracy, lucidity, completeness, succinctness, appropriateness, and usefulness.
* **Custom Labels for Easy Filtering:** Add custom labels as headers for your model requests. These labels will appear in the logs, making it easier for you to filter and locate specific requests.
* **Intelligent Routing Based on Your Preferences:** Choose your key settings based on speed, cost, and quality. We make routing decisions according to your preference, ensuring that all requests made with that key follow your set heuristic.
* **Transparent Response Conversions:** We uphold a clean interface with accurate conversions. If you send a request through our chat completion endpoint but we select a non-chat completion model, we'll handle the conversion for you.
* **Detailed Response Metrics:** We enrich your response data with extensive metrics, including unique ID, usage, costs, model selected, latency, tokens used, temperature, and cost savings compared to benchmark models.
* **Advanced Logging and Observability:** Pulze.ai acts as your outsourced logging provider for all requests made through our platform, ensuring streamlined large language model operations.
* **Cost Efficiency:** Save costs by letting us guide you to the most cost-effective solutions. Our platform tracks your costs and compares them to the leading top model to show you how much you're saving.
* **Comprehensive Evaluation:** With Pulze.ai, you secure thorough and automated evaluation of large language models. Save time and refine your choice for specific tasks and applications.
* **Pulze Playground:** Experiment with different settings, balancing speed, cost, and quality in our playground environment. Get a feel for the capabilities of our model routing layer or embed to your homepage easily.
* **API Access:** Generate a "secret key" to access our API. Equip your customers with access to the most advanced large language models (LLMs) currently available.
* **Source from Leading AI Labs:** Our models are obtained from industry-leading AI research labs such as AI21 Labs, Anthropic, Cohere, OpenAI, and GooseAI, each designed to operate at peak levels considering diverse factors.
* **Prompt Execution and Inference:** Enhance prompt generation, adjust pipelines, authenticate LLM outputs, and safeguard against prompt injection attacks with Pulze.ai. All of these benefits come standard with our platform.
* **Open source models:** Integrate with any open-source model and utilize in your application.

### Setting up and Using Pulze.ai API with OpenAI's Python SDK

Here's how to setup and use Pulze.ai API in your applications using OpenAI's Python SDK (1.12.0):

```python theme={null}
import openai
openai.api_key = "<$PULZE_API_KEY>"
openai.base_url = "https://api.pulze.ai/v1/" # with trailing slash!

text_response = openai.completions.create(
  model="pulze-v0",
  prompt="Say Hello World!",
)

chat_response = openai.chat.completions.create(
  model="pulze",
  messages=[{
    "role": "user",
    "content": "Say Hello World!"
  }],
)

print(text_response, chat_response)
```

### Using Pulze.ai with LangChain

You can also integrate Pulze.ai with LangChain as follows:

```python theme={null}
from langchain.models import OpenAI

pulze_model = OpenAI(
  openai_api_key="<$PULZE_API_KEY>",
  openai_api_base="https://api.pulze.ai/v1/"  # with trailing slash!
  model="pulze",
  max_tokens=256,
  temperature=0.4,
)

pulze_model.predict("Say Hello World!")
```
