Villanova-2B-VL-2603 is a fully open, multilingual Vision-Language Model developed by Villanova.AI. Part of the Villanova project, it extends our text-only Villanova-2B-2603 to visual understanding while preserving native support for five European languages. All model weights, training data sources, and training details are publicly released.
Built on a LLaVA-style architecture pairing a SigLIP vision encoder with the Villanova-2B-Base-2603 language backbone, this ~2.8B-parameter model delivers strong multimodal understanding, visual question answering, and multilingual image captioning under a fully open Apache 2.0 license.
European-focused, fully open VLM released under Apache 2.0
Native multilingual support for 5 European languages: English, French, German, Italian, and Spanish, including multilingual image captioning (XM3600) and visual instruction following
Broad visual understanding across general VQA (RealWorldQA, CVQA, MME) and multilingual benchmarks (Multi-MMBench, Multi-AI2D)
Preserves text-only capabilities of the Villanova-2B-2603 language backbone through text-only data mixing in Stage 2
Only ~2.8B parameters, efficient enough for single-GPU inference
Projector-only alignment on multilingual image-caption pairs

Training Recipe (Stage 1: Projector Alignment)
Stage 1 aligns the vision encoder output to the language model embedding space by training only the multimodal projector, with both the vision tower and the LLM fully frozen. This is a lightweight warmup that teaches the projector how to map SigLIP visual features into the Villanova-2B token space before any instruction tuning.
Both stages use only permissively-licensed data (no GPT/Claude-generated content). The curated multilingual derivatives (the Multi-* datasets, translated and post-processed in EN/DE/ES/FR/IT) are released by Villanova.AI on the HuggingFace Hub.

Evaluation
Villanova-2B-VL-2603 was evaluated using VLMEvalKit on a suite of standard and multilingual VLM benchmarks covering multiple-choice reasoning, general visual question answering, hallucination robustness, and cross-lingual visual understanding. All evaluations use exact_matching judging (no LLM-as-judge) for full reproducibility.
We compare against Salamandra-VL-7B, a strong European VLM built on the same language family.
Despite using less than a third of the parameters (~2.8B vs ~8.9B), Villanova-2B-VL-2603 matches Salamandra-VL-7B overall, with particular strengths on general VQA and multilingual benchmarks. Multilingual benchmarks are reported as the average across EN/DE/ES/FR/IT.

The Overall row is the unweighted average across the 10 benchmarks on the 0-100 scale. MME and OCRBench are excluded because they use different scoring scales (0-2800 and 0-1000 respectively).
Multilingual Evaluation (Per-Language Detail)
The multilingual benchmarks (Multi-MMBench, Multi-AI2D, Multi-MMStar) are extensions of the standard benchmarks with parallel test sets in 5 European languages. Below is the per-language breakdown.

Key takeaways:
Competitive overall average (53.9 vs 54.8) against a model with ~3.2x more parameters
Wins on general VQA: RealWorldQA, CVQA, and MME all outperform Salamandra-VL-7B
Solid multilingual capability across EN/DE/ES/FR/IT, with a particularly strong Multi-AI2D improvement (+8.0 avg, wins on all 5 languages) over Salamandra-VL-7B
Balanced per-language performance: on Multi-AI2D and Multi-MMBench, Villanova performs uniformly across DE/EN/ES/FR/IT (no language collapse)
Intended Use
Multilingual image captioning and description
Visual question answering (single-image)
Document and chart understanding (OCR-light tasks)
Multimodal instruction following in EN/DE/ES/FR/IT
Research on fully-open European VLMs
Limitations
Single-image inference only (no multi-image or video support)
OCR quality on dense, small-text documents is limited compared to specialized OCR-heavy VLMs
As with all VLMs, outputs can contain hallucinations; users should verify factual claims
