Qwen2.5-Coder-7B-SysMLv2

Qwen2.5-Coder-SysMLv2 is a domain-specialized model adapted from Qwen 2.5 Coder to generate, understand, and reason about SysML v2 textual modeling. This model focuses specifically on structure modeling, option-space exploration, and low-syntax-error generation for automated MBSE pipelines.

🚀 Overview

🎯 Purpose

Qwen2.5-Coder-SysMLv2 is optimized for scenarios where you want to turn natural language requirements into SysML v2 architecture options — reliably — with significantly reduced syntax issues compared to direct SysML generation.

This model is especially suited for agentic orchestration pipelines where the SysML is either:

1. directly returned as SysML syntax or
2. generated as JSON → converted into valid SysML v2

🧠 Capabilities

• ✅ SysML v2 Structure Generation Generates SysML v2 package / part definitions from requirement text.

• 🔁 Multiple Architecture Options Generates usually 3 alternative model structures per prompt (for architectural trade-off exploration).

• 🧩 Pipeline Friendly Supports JSON → XMI → SysML v2 conversion workflows (lowest syntax error mode).

• 🔍 Domain Reasoning Good at structural decomposition of warehouses, manufacturing, logistics, robotics, automation, sensor networks, cyber-physical systems.

• 🧱 Toolchain Integration Ready

  • LangGraph → multi-step modeling agents
  • MCP → SysML diagram rendering pipeline
  • vLLM & Ollama → inference serving

🧩 Example Usage Prompt Pattern

prompt

You are a SysML v2 structural model architect.

Given the requirement text below:
- generate 3 candidate SysML v2 structural architecture options
- do NOT include behavior
- output only valid SysML v2 textual syntax

Requirement:
"The warehouse needs an automated guided vehicle fleet, inventory storage racks, and a central planning server that dispatches missions to AGVs."

Notes

This model is intended to be chained inside agent graph / multi-step workflows — NOT to replace formal SysML tools — but to massively accelerate first-pass structure modeling, alternative exploration, and early model formation inside engineering loops.

This is a research-focused domain adaptation intended for actual industrial MBSE work.
