Flui3d Chat Model Qwen 2.5 Reasoning
Model Description
This model is a Fine-tuned version of Qwen 2.5 designed for microfluidic chip design generation . The model incorporates Chain-of-Thought (CoT) reasoning to translate high-level design requirements into structured microfluidic system descriptions.
The model generates outputs in a
structured JSON format following a predefined schema (see:
Output Format ). The generated JSON describes a
complete microfluidic chip , including:
microfluidic components
component parameters
channel connections
structural relationships between elements
This allows the model to act as a design file generator for microfluidic systems , enabling automated or AI-assisted microfluidic chip design workflows.
The repository includes:
LoRA Adapter weights Quantized, split GGUF model files compatible with Ollama, may require merging before use
GGUF files can be merged using tools provided by llama.cpp (see:
Merging Split GGUF Files ).
Intended Use
This model is intended for:
Automated microfluidic chip design generation AI-assisted CAD workflows for microfluidics Research in AI-assisted scientific design Programmatic generation of microfluidic device specifications
The model converts natural language design requirements into structured microfluidic design specifications .
Example Applications
Rapid prototyping of microfluidic devices
Automated generation of chip layouts
Integration with microfluidic CAD pipelines
AI-driven design exploration

Repository Contents
This repository includes:
1. LoRA Adapter
The LoRA adapter can be loaded on top of the base Qwen model for inference or further fine-tuning.
2. Quantized GGUF Models
Quantized GGUF format models compatible with:
Due to file size limitations, the GGUF models are split into multiple parts . These files must be merged before use.
Merging Split GGUF Files
To merge the split GGUF files, use the merging utilities from llama.cpp :
https://github.com/ggml-org/llama.cpp/blob/master/tools/gguf-split/README.mdUsage with Ollama
The merged GGUF file can be used with:
Example prompt:
Design a microfluidic chip with two inlets, one mixer, and a single outlet.
Limitations
The model assumes valid schema-based output format and may produce invalid JSON if prompts are poorly structured.
Generated designs should be validated before fabrication .
The model does not replace domain expert verification .
