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 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 Gemma-2b (2.51 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:

import torch
from transformers import AutoModelForCausalLM, AutoTokenizer
model_id = "NexaAIDev/octo-planner-2b"
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.
    """
