• Model Type: Multimodal, Vision-Language Model
• Architecture: llava-v1.5-13b
• Model Size: 13.4B parameters (FP16)

Model Overview

SpaceLLaVA is a vision-language model adapted from LLaVA-1.5 (13B) and fine-tuned by LoRA to improve spatial reasoning. Trained using a synthetic VQA dataset inspired by the methods described in SpatialVLM. SpaceLLaVA demonstrates strong qualitative and quantitative spatial reasoning after distilling 3D scene understanding from the pipelines in VQASynth.

Running SpaceLLaVA

GGUF

Use this notebook to query spatial relationships between objects in a scene with llama-cpp-python.

⚠️ Limitations & Ethical Considerations

• Performance may degrade in cluttered environments or camera perspective.
• This model was fine-tuned using synthetic reasoning over an internet image dataset.
• Multimodal biases inherent to the base model (LLaVA) may persist.
• Not intended for use in safety-critical or legal decision-making.

Users are encouraged to evaluate outputs critically and consider fine-tuning for domain-specific safety and performance.
