OTA-v1

Introduction

OTA-v1 is a specialized Browser Agent Model (BAM) fine-tuned from the Qwen2.5-14B base model. Designed to excel in controlling browser environments, OTA-v1 leverages frameworks like browser-use to perform automated browser tasks with high precision. Unlike traditional instruction-tuned models, OTA-v1 is optimized for reasoning and tool use within browser contexts, making it a powerful tool for web automation and interaction.

Features

Cost-Efficient Deployment:
- Optimized for consumer-grade GPUs (NVIDIA 3090/4090) with 16-bit precision (20GB VRAM) and 4-bit quantization (10GB VRAM)
- Enabling local execution without cloud dependencies
Multi-step Planning Engine:
- Automatically decomposes complex tasks into executable action sequences
- Implements conditional logic for error recovery and retry mechanisms
- Maintains state awareness across browser sessions (tabs/windows)
Precision Tool Utilization:
- Native support for browser agent frameworks (browser-use)
- Automatic detection of interactive elements and form fields
Long-context Optimization:
- Processes full-page DOM structures (up to 128K tokens)
- YARN-enhanced attention patterns for efficient HTML traversal
- Context-aware element resolution within dynamic web applications
Structured Execution: Generates battle-tested tool use instructions with:
- Formatted tool use output under long context
- Self correction based on previous action history

Quickstart

Here provides a code snippet with apply_chat_template to show you how to load the tokenizer and model and how to generate contents.

from transformers import AutoModelForCausalLM, AutoTokenizer

model_name = "OTA-AI/OTA-v1"

model = AutoModelForCausalLM.from_pretrained(
    model_name,
    torch_dtype="auto",
    device_map="auto"
)
tokenizer = AutoTokenizer.from_pretrained(model_name)

prompt = "Give me a short introduction to large language model."
messages = [
    {"role": "system", "content": "You are Qwen, created by Alibaba Cloud. You are a helpful assistant."},
    {"role": "user", "content": prompt}
]
text = tokenizer.apply_chat_template(
    messages,
    tokenize=False,
    add_generation_prompt=True
)
model_inputs = tokenizer([text], return_tensors="pt").to(model.device)

generated_ids = model.generate(
    **model_inputs,
    max_new_tokens=512
)
generated_ids = [
    output_ids[len(input_ids):] for input_ids, output_ids in zip(model_inputs.input_ids, generated_ids)
]

response = tokenizer.batch_decode(generated_ids, skip_special_tokens=True)[0]
