Model Overview

Orsta-32B-0321 is a cutting-edge vision-language model (VLM) designed to achieve superior performance across a wide spectrum of both visual reasoning and visual perception tasks. This model is a result of post-training with V-Triune, our novel unified reinforcement learning (RL) system.

The V-Triune system enables VLMs to be jointly optimized on diverse multimodal tasks within a single, cohesive training pipeline. Orsta-32B-0321 has been specifically trained using V-Triune on a carefully curated set of eight challenging visual tasks, fostering robust generalization and enhanced capabilities.

Training with V-Triune

Orsta-32B-0321's advanced abilities stem from its training with the V-Triune system. Key aspects of its training include:

• Unified RL Framework (V-Triune): V-Triune is a Visual Triple-Unified Reinforcement Learning system featuring three core complementary components:

  • Sample-Level Data Formatting (to unify diverse task inputs)
  • Verifier-Level Reward Computation (to deliver custom rewards via specialized verifiers)
  • Source-Level Metric Monitoring (to diagnose problems at the data-source level)   * It also incorporates an innovative Dynamic IoU reward mechanism, crucial for optimizing visual perception tasks. You can find more details in our paper: V-Triune

• Diverse Joint Task Optimization: Orsta-32B-0321 was jointly optimized on the following eight visual tasks:

  • Visual Reasoning Tasks: Mathematics, Science Question Answering, Chart Understanding, and Puzzle Solving.
  • Visual Perception Tasks: Object Detection, Visual Grounding, Optical Character Recognition (OCR), and Object Counting.

This comprehensive training allows Orsta-32B-0321 to develop a deeper understanding of visual content and its relation to textual prompts, excelling in tasks that require intricate reasoning and precise perception.

How to Use

Orsta-32B-0321 is developed by post-training the Qwen2.5-VL-32B-Instruct (0321 checkpoint) model using our V-Triune reinforcement learning system. The Qwen2.5-VL-32B-Instruct (0321 checkpoint) is a publicly available baseline known for its reliable core reasoning abilities, alongside certain recognized limitations in perception and output formatting (which have been addressed in subsequent Qwen releases). Applying V-Triune to this specific baseline demonstrates its powerful post-training capability to unlock the model's inherent potential and significantly elevate its performance by refining and amplifying existing strengths.

Consequently, the core usage of Orsta-32B-0321, particularly regarding input formatting and model interaction, largely follows the established patterns of the Qwen2.5-VL series. Users familiar with Qwen2.5-VL models should find the interface intuitive.

For comprehensive details on the general capabilities of Qwen2.5-VL models, including multi-turn dialogue format and image input specifics, we recommend referring to the official Qwen2.5-VL series documentation (please ensure to consult information relevant to the 32B Instruct version).
