# Octo-planner: On-device Language Model for Planner-Action Agents Framework

We're thrilled to introduce the Octo-planner, the latest breakthrough in on-device language models from Nexa AI. Developed for the Planner-Action Agents Framework, Octo-planner enables rapid and efficient planning without the need for cloud connectivity, this model together with [Octopus-V2](https://huggingface.co/NexaAIDev/Octopus-v2) can work on edge devices locally to support AI Agent usages.

### Key Features of Octo-planner:
- **Efficient Planning**: Utilizes fine-tuned plan model based on Phi-3 Mini (3.82 billion parameters) for high efficiency and low power consumption.
- **Agent Framework**: Separates planning and action, allowing for specialized optimization and improved scalability.
- **Enhanced Accuracy**: Achieves a planning success rate of 98.1% on benchmark dataset, providing reliable and effective performance.
- **On-device Operation**: Designed for edge devices, ensuring fast response times and enhanced privacy by processing data locally.


## Example Usage
Below is a demo of Octo-planner:
<p align="center" width="100%">
<a><img src="1-demo.png" alt="ondevice" style="width: 80%; min-width: 300px; display: block; margin: auto;"></a>
</p>


Run below code to use Octopus Planner for a given question:
```python
import torch
from transformers import AutoModelForCausalLM, AutoTokenizer

model_id = "NexaAIDev/octopus-planning"
model = AutoModelForCausalLM.from_pretrained(model_id, device_map="auto", torch_dtype=torch.bfloat16, trust_remote_code=True)
tokenizer = AutoTokenizer.from_pretrained(model_id)

question = "Find my presentation for tomorrow's meeting, connect to the conference room projector via Bluetooth, increase the screen brightness, take a screenshot of the final summary slide, and email it to all participants"
inputs = f"<|user|>{question}<|end|><|assistant|>"
input_ids = tokenizer(inputs, return_tensors="pt").to(model.device)
outputs = model.generate(
        input_ids=input_ids["input_ids"], 
        max_length=1024,
        do_sample=False)
res = tokenizer.decode(outputs.tolist()[0])
print(f"=== inference result ===\n{res}")
```

## Training Data
We wrote 10 Android API descriptions to used to train the models, see this file for details. Below is one Android API description example
```
def send_email(recipient, title, content):
    """
    Sends an email to a specified recipient with a given title and content.

    Parameters:
    - recipient (str): The email address of the recipient.
    - title (str): The subject line of the email. This is a brief summary or title of the email's purpose or content.
    - content (str): The main body text of the email. It contains the primary message, information, or content that is intended to be communicated to the recipient.
    """
