Qwen2-VL-7B-Geometry

The Geometry expert of the OptMerge MLLM merging benchmark (ICLR 2026). It is one of five capability experts (VQA, Geometry, Chart, OCR, Grounding) fine-tuned from the same base model, so that they can be merged into one model without training data.

Paper: OptMerge: Unifying Multimodal LLM Capabilities and Modalities via Model Merging (OpenReview)
Extended version (SWUDI): Closed-Form Spectral Regularization for Multi-Task Model Merging, which also uses these experts in its multimodal merging benchmark
Code: WalkerWorldPeace/MLLMerging
All experts: MLLMerging collection

Training

Base model: Qwen/Qwen2-VL-7B
Method: LoRA fine-tuning (rank 8, learning rate 1e-5, warmup ratio 0.1, cosine schedule, 1 epoch). The LoRA weights are merged into this full checkpoint.
Data: GeoQA+ (zh), G-LLaVA (190K samples, Table 1 of the paper).

Results

From Table 3 of the paper. The last row merges this expert with the other four experts using OptMerge.

Model	VizWiz	GQA	MathVista	MATH-Vision	ChartQA	TextVQA	OCRVQA	RefCOCO	RefCOCO+	RefCOCOg	Avg.
Qwen2-VL-7B (base model)	5.52	5.39	47.85	23.68	0.36	20.22	1.07	45.32	37.55	31.26	21.82
Qwen2-VL-7B-Geometry	35.57	44.63	42.50	28.95	14.56	73.95	45.96	5.57	2.31	3.90	29.79
OptMerge (5 experts merged)	41.61	61.16	48.66	40.79	74.08	81.54	60.06	80.92	65.90	78.24	63.30

Usage

from transformers import AutoProcessor, Qwen2VLForConditionalGeneration

model_id = "yongxianwei/Qwen2-VL-7B-Geometry"
model = Qwen2VLForConditionalGeneration.from_pretrained(model_id, torch_dtype="auto", device_map="auto")
processor = AutoProcessor.from_pretrained(model_id)
# Build chat messages and call model.generate(...) as in the official Qwen2-VL model card.
