# ViCA-7B: Visuospatial Cognitive Assistant > You may also be interested in our other project, **ViCA2**. Please refer to the following links: [![GitHub](https://img.shields.io/badge/GitHub-ViCA2-181717?logo=github&logoColor=white)](https://github.com/nkkbr/ViCA) [![Hugging Face Models](https://img.shields.io/badge/%F0%9F%A4%97%20Hugging%20Face-ViCA2-blue)](https://huggingface.co/nkkbr/ViCA2) ## Overview **ViCA-7B** is a vision-language model specifically fine-tuned for *visuospatial reasoning* in indoor video environments. Built upon the LLaVA-Video-7B-Qwen2 architecture, it is trained using our newly proposed **ViCA-322K dataset**, which emphasizes both structured spatial annotations and complex instruction-based reasoning tasks. ViCA-7B achieves **state-of-the-art performance** on [VSI-Bench](https://github.com/vision-x-nyu/thinking-in-space), outperforming both proprietary models like **GPT-4o** and **Gemini-1.5 Pro**, as well as larger open-source baselines. > **ViCA-7B sets a new standard for open-source multimodal spatial reasoning on indoor videos, making it a strong candidate for embodied AI and robotics use cases.**

Figure 1: Performance comparison of ViCA-7B and other models on VSI-Bench.

## Model Architecture and Training Strategy ViCA-7B is built upon the [LLaVA-NeXT](https://github.com/LLaVA-VL/LLaVA-NeXT) framework, using **Qwen2-7B** as the language backbone and **SigLIP** as the visual encoder. **Key Training Features** - **Fixed-Length Visual Tokenization** Each video is uniformly sampled into 64 frames, and each frame is encoded into 210 visual tokens, resulting in a total of **13,440 visual tokens per example**. This fixed-length design ensures consistent memory usage and stable optimization across batches. - **Multimodal Alignment via Lightweight Projector** A simple MLP-based projector maps visual embeddings into the language embedding space, enabling effective fusion between video content and textual prompts during both training and inference. - **Efficient Distributed Training with DeepSpeed** Training is conducted using **DeepSpeed ZeRO-3 Offload** on **8Γ— NVIDIA H100 80GB GPUs**, with full parameter and optimizer state partitioning across devices. This setup supports large batch sizes and minimizes GPU memory overhead. - **Mixed-Precision Computation (fp16)** We adopt **mixed-precision training (fp16)** to accelerate computation and reduce memory usage, without compromising accuracy. This is combined with ZeRO-3 partitioning to further enhance training scalability. The training was conducted over **55 hours**, covering both base and complex spatial reasoning subsets. ## Training Dynamics

## Dataset ViCA-7B is fine-tuned on two complementary datasets: - [**ViCA-322K**](https://huggingface.co/datasets/nkkbr/ViCA-322K): A large-scale dataset covering both **base spatial reasoning tasks** (e.g., object distance, size, count, appearance order) and **complex spatial reasoning tasks** involving natural language questions and scene understanding. This dataset forms the core of the model's spatial reasoning capabilities. - [**ViCA-thinking-2.68k**](https://huggingface.co/datasets/nkkbr/ViCA-thinking-2.68k): A focused dataset used for instruction tuning to enhance the model's ability to **generate step-by-step reasoning traces** before outputting final answers. This supports more interpretable and cognitively-aligned response generation. For details, please refer to the individual dataset pages linked above. ## Evaluation: VSI-BENCH Benchmark

Figure 3: Quantitative comparison of ViCA-7B and baseline models on VSI-Bench. ViCA-7B achieves the best overall performance across both numerical and multiple-choice tasks.

### Effect of CSR Data | Configuration | Avg Score | |----------------------|-----------| | Base-only (281K) | 55.35 | | Full with CSR (322K) | **60.56** | > CSR(Complex Spatial Reasoning) boosts generalization and **accelerates learning**, with notable performance jumps at intermediate checkpoints (e.g., +2.02 at 50–55%). ### Data Scale vs. Performance Performance improves significantly between **5% β†’ 60%** of data usage. After **80%**, improvements plateau, indicating dataset is well-matched to model capacity.

Figure 4: Performance of ViCA-7B under varying training data sizes (from 5% to 100%). The full dataset (including Complex Spatial Reasoning, CSR) consistently outperforms the base-only configuration. Notably, the CSR-enhanced model shows a +2.02 score jump between 50% and 55%, and a final performance gain of +4.75 at full scale. Performance plateaus beyond 80%, indicating the dataset is well-aligned with the model capacity.

## Intermediate Checkpoints and Evaluation Outputs To support detailed analysis and reproducibility, we provide two sets of intermediate checkpoints saved at every **5% increment** of the training data. These models are trained for a single epoch and are useful for understanding how performance evolves as training progresses. We also release the corresponding **raw evaluation outputs** (e.g., `.json` prediction files) for each checkpoint. The evaluation script used to produce these outputs is available in our [GitHub repository](https://github.com/nkkbr/ViCA). ### Full Dataset (ViCA-322K: Base + CSR) This series corresponds to the full training set, including both base spatial reasoning and complex spatial reasoning (CSR): | Data Usage | Checkpoint | Data Usage | Checkpoint | | ---------- | --------------------------------------------------------- | ---------- | ----------------------------------------------------------- | | 5% | [`nkkbr/ViCA-5p`](https://huggingface.co/nkkbr/ViCA-5p) | 55% | [`nkkbr/ViCA-55p`](https://huggingface.co/nkkbr/ViCA-55p) | | 10% | [`nkkbr/ViCA-10p`](https://huggingface.co/nkkbr/ViCA-10p) | 60% | [`nkkbr/ViCA-60p`](https://huggingface.co/nkkbr/ViCA-60p) | | 15% | [`nkkbr/ViCA-15p`](https://huggingface.co/nkkbr/ViCA-15p) | 65% | [`nkkbr/ViCA-65p`](https://huggingface.co/nkkbr/ViCA-65p) | | 20% | [`nkkbr/ViCA-20p`](https://huggingface.co/nkkbr/ViCA-20p) | 70% | [`nkkbr/ViCA-70p`](https://huggingface.co/nkkbr/ViCA-70p) | | 25% | [`nkkbr/ViCA-25p`](https://huggingface.co/nkkbr/ViCA-25p) | 75% | [`nkkbr/ViCA-75p`](https://huggingface.co/nkkbr/ViCA-75p) | | 30% | [`nkkbr/ViCA-30p`](https://huggingface.co/nkkbr/ViCA-30p) | 80% | [`nkkbr/ViCA-80p`](https://huggingface.co/nkkbr/ViCA-80p) | | 35% | [`nkkbr/ViCA-35p`](https://huggingface.co/nkkbr/ViCA-35p) | 85% | [`nkkbr/ViCA-85p`](https://huggingface.co/nkkbr/ViCA-85p) | | 40% | [`nkkbr/ViCA-40p`](https://huggingface.co/nkkbr/ViCA-40p) | 90% | [`nkkbr/ViCA-90p`](https://huggingface.co/nkkbr/ViCA-90p) | | 45% | [`nkkbr/ViCA-45p`](https://huggingface.co/nkkbr/ViCA-45p) | 95% | [`nkkbr/ViCA-95p`](https://huggingface.co/nkkbr/ViCA-95p) | | 50% | [`nkkbr/ViCA-50p`](https://huggingface.co/nkkbr/ViCA-50p) | 100% (This repo) | [`nkkbr/ViCA`](https://huggingface.co/nkkbr/ViCA) | Raw evaluation outputs are available [here](https://huggingface.co/nkkbr/ViCA/tree/main/raw_evaluation_outputs/vsi-bench_all_data/). ### Base-only Subset (ViCA-322K: Base) This series is trained **only** on the base spatial reasoning subset of ViCA-322K, without any CSR examples: | Data Usage | Checkpoint | Data Usage | Checkpoint | | ---------- | ------------------------------------------------------------------- | ---------- | --------------------------------------------------------------------- | | 5% | [`nkkbr/ViCA-base-5p`](https://huggingface.co/nkkbr/ViCA-base-5p) | 55% | [`nkkbr/ViCA-base-55p`](https://huggingface.co/nkkbr/ViCA-base-55p) | | 10% | [`nkkbr/ViCA-base-10p`](https://huggingface.co/nkkbr/ViCA-base-10p) | 60% | [`nkkbr/ViCA-base-60p`](https://huggingface.co/nkkbr/ViCA-base-60p) | | 15% | [`nkkbr/ViCA-base-15p`](https://huggingface.co/nkkbr/ViCA-base-15p) | 65% | [`nkkbr/ViCA-base-65p`](https://huggingface.co/nkkbr/ViCA-base-65p) | | 20% | [`nkkbr/ViCA-base-20p`](https://huggingface.co/nkkbr/ViCA-base-20p) | 70% | [`nkkbr/ViCA-base-70p`](https://huggingface.co/nkkbr/ViCA-base-70p) | | 25% | [`nkkbr/ViCA-base-25p`](https://huggingface.co/nkkbr/ViCA-base-25p) | 75% | [`nkkbr/ViCA-base-75p`](https://huggingface.co/nkkbr/ViCA-base-75p) | | 30% | [`nkkbr/ViCA-base-30p`](https://huggingface.co/nkkbr/ViCA-base-30p) | 80% | [`nkkbr/ViCA-base-80p`](https://huggingface.co/nkkbr/ViCA-base-80p) | | 35% | [`nkkbr/ViCA-base-35p`](https://huggingface.co/nkkbr/ViCA-base-35p) | 85% | [`nkkbr/ViCA-base-85p`](https://huggingface.co/nkkbr/ViCA-base-85p) | | 40% | [`nkkbr/ViCA-base-40p`](https://huggingface.co/nkkbr/ViCA-base-40p) | 90% | [`nkkbr/ViCA-base-90p`](https://huggingface.co/nkkbr/ViCA-base-90p) | | 45% | [`nkkbr/ViCA-base-45p`](https://huggingface.co/nkkbr/ViCA-base-45p) | 95% | [`nkkbr/ViCA-base-95p`](https://huggingface.co/nkkbr/ViCA-base-95p) | | 50% | [`nkkbr/ViCA-base-50p`](https://huggingface.co/nkkbr/ViCA-base-50p) | 100% | [`nkkbr/ViCA-base`](https://huggingface.co/nkkbr/ViCA-base) | Raw evaluation outputs are available [here](https://huggingface.co/nkkbr/ViCA/tree/main/raw_evaluation_outputs/vsi-bench_only_base/). ## Source-wise Checkpoints While the full **ViCA-322K** dataset was curated by us, the underlying videos and associated metadata are sourced from three distinct indoor video datasets: * **[ARKitScenes](https://machinelearning.apple.com/research/arkitscenes)** * **[ScanNet](http://www.scan-net.org)** * **[ScanNet++](https://kaldir.vc.in.tum.de/scannetpp/)** To better understand how each source contributes to model performance, we fine-tuned ViCA-7B on subsets of ViCA-322K that exclusively use data from each source. For each subset, we provide checkpoints trained with **10% increments** of the available data, from 10% to 100%. Corresponding **raw evaluation outputs** (e.g., `.json` predictions) are also provided for all checkpoints. ### ARKitScenes-Only Checkpoints | Data Usage | Checkpoint | Data Usage | Checkpoint | | ---------- | --------------------------------------------------------------------------------- | ---------- | ----------------------------------------------------------------------------------- | | 10% | [`nkkbr/ViCA-ARKitScenes-10p`](https://huggingface.co/nkkbr/ViCA-ARKitScenes-10p) | 60% | [`nkkbr/ViCA-ARKitScenes-60p`](https://huggingface.co/nkkbr/ViCA-ARKitScenes-60p) | | 20% | [`nkkbr/ViCA-ARKitScenes-20p`](https://huggingface.co/nkkbr/ViCA-ARKitScenes-20p) | 70% | [`nkkbr/ViCA-ARKitScenes-70p`](https://huggingface.co/nkkbr/ViCA-ARKitScenes-70p) | | 30% | [`nkkbr/ViCA-ARKitScenes-30p`](https://huggingface.co/nkkbr/ViCA-ARKitScenes-30p) | 80% | [`nkkbr/ViCA-ARKitScenes-80p`](https://huggingface.co/nkkbr/ViCA-ARKitScenes-80p) | | 40% | [`nkkbr/ViCA-ARKitScenes-40p`](https://huggingface.co/nkkbr/ViCA-ARKitScenes-40p) | 90% | [`nkkbr/ViCA-ARKitScenes-90p`](https://huggingface.co/nkkbr/ViCA-ARKitScenes-90p) | | 50% | [`nkkbr/ViCA-ARKitScenes-50p`](https://huggingface.co/nkkbr/ViCA-ARKitScenes-50p) | 100% | [`nkkbr/ViCA-ARKitScenes`](https://huggingface.co/nkkbr/ViCA-ARKitScenes) | πŸ”— Raw evaluation outputs: [ARKitScenes results](https://huggingface.co/nkkbr/ViCA/tree/main/raw_evaluation_outputs/vsi-bench_arkitscenes/) ### ScanNet++-Only Checkpoints | Data Usage | Checkpoint | Data Usage | Checkpoint | | ---------- | ----------------------------------------------------------------------------- | ---------- | ------------------------------------------------------------------------------- | | 10% | [`nkkbr/ViCA-ScanNetPP-10p`](https://huggingface.co/nkkbr/ViCA-ScanNetPP-10p) | 60% | [`nkkbr/ViCA-ScanNetPP-60p`](https://huggingface.co/nkkbr/ViCA-ScanNetPP-60p) | | 20% | [`nkkbr/ViCA-ScanNetPP-20p`](https://huggingface.co/nkkbr/ViCA-ScanNetPP-20p) | 70% | [`nkkbr/ViCA-ScanNetPP-70p`](https://huggingface.co/nkkbr/ViCA-ScanNetPP-70p) | | 30% | [`nkkbr/ViCA-ScanNetPP-30p`](https://huggingface.co/nkkbr/ViCA-ScanNetPP-30p) | 80% | [`nkkbr/ViCA-ScanNetPP-80p`](https://huggingface.co/nkkbr/ViCA-ScanNetPP-80p) | | 40% | [`nkkbr/ViCA-ScanNetPP-40p`](https://huggingface.co/nkkbr/ViCA-ScanNetPP-40p) | 90% | [`nkkbr/ViCA-ScanNetPP-90p`](https://huggingface.co/nkkbr/ViCA-ScanNetPP-90p) | | 50% | [`nkkbr/ViCA-ScanNetPP-50p`](https://huggingface.co/nkkbr/ViCA-ScanNetPP-50p) | 100% | [`nkkbr/ViCA-ScanNetPP`](https://huggingface.co/nkkbr/ViCA-ScanNetPP) | πŸ”— Raw evaluation outputs: [ScanNet++ results](https://huggingface.co/nkkbr/ViCA/tree/main/raw_evaluation_outputs/vsi-bench_scannetpp/) ### ScanNet-Only Checkpoints | Data Usage | Checkpoint | Data Usage | Checkpoint | | ---------- | ------------------------------------------------------------------------- | ---------- | --------------------------------------------------------------------------- | | 10% | [`nkkbr/ViCA-ScanNet-10p`](https://huggingface.co/nkkbr/ViCA-ScanNet-10p) | 60% | [`nkkbr/ViCA-ScanNet-60p`](https://huggingface.co/nkkbr/ViCA-ScanNet-60p) | | 20% | [`nkkbr/ViCA-ScanNet-20p`](https://huggingface.co/nkkbr/ViCA-ScanNet-20p) | 70% | [`nkkbr/ViCA-ScanNet-70p`](https://huggingface.co/nkkbr/ViCA-ScanNet-70p) | | 30% | [`nkkbr/ViCA-ScanNet-30p`](https://huggingface.co/nkkbr/ViCA-ScanNet-30p) | 80% | [`nkkbr/ViCA-ScanNet-80p`](https://huggingface.co/nkkbr/ViCA-ScanNet-80p) | | 40% | [`nkkbr/ViCA-ScanNet-40p`](https://huggingface.co/nkkbr/ViCA-ScanNet-40p) | 90% | [`nkkbr/ViCA-ScanNet-90p`](https://huggingface.co/nkkbr/ViCA-ScanNet-90p) | | 50% | [`nkkbr/ViCA-ScanNet-50p`](https://huggingface.co/nkkbr/ViCA-ScanNet-50p) | 100% | [`nkkbr/ViCA-ScanNet`](https://huggingface.co/nkkbr/ViCA-ScanNet) | πŸ”— Raw evaluation outputs: [ScanNet results](https://huggingface.co/nkkbr/ViCA/tree/main/raw_evaluation_outputs/vsi-bench_scannet/) ## Additional Probing ### Time Instructions Including 64 frame timestamps in the prompt slightly **hurts** performance, suggesting that models fail to leverage temporal alignment and are negatively impacted by instruction verbosity.

Figure 5: Adding explicit frame timestamps (64 values) degrades model performance on VSI-Bench, indicating an inability to exploit temporal alignment and sensitivity to prompt length.

--- ### More Frames Increasing input from 64 to 128 frames doubles the number of visual tokens (13,440 β†’ 26,880) but yields **no performance gain**, highlighting overfitting to fixed token length and architectural inflexibility.

Figure 6: Comparison between 64-frame and 128-frame inputs. Despite doubling the visual token count, performance remains unchanged, indicating overfitting to fixed-length input and limited adaptability to variable-length sequences.

## Potential Applications ViCA-7B supports a broad range of spatially grounded multimodal applications: - Indoor navigation assistants - Robotics planning and spatial querying - Smart room arrangement and AR layout analysis - Scene understanding for embodied AI agents ## Known Limitations - Limited temporal reasoning: Time instructions not effectively utilized - Frame scaling issues: Models expect fixed input lengths - No depth/point cloud: Only RGB video input supported - Zero-shot generalization is good, but not task-agnostic ## Download You can download the model weights to your local environment (optional). ```python from huggingface_hub import snapshot_download save_dir = "./ViCA" repo_id = "nkkbr/ViCA" cache_dir = save_dir + "/cache" snapshot_download(cache_dir=cache_dir, local_dir=save_dir, repo_id=repo_id, local_dir_use_symlinks=False, resume_download=True, ) ``` ## Inference *Here is a runnable example using ViCA-7B on a VSI-Bench question.* ```python # This inference script is adapted from: # https://huggingface.co/lmms-lab/LLaVA-Video-7B-Qwen2 # pip install git+https://github.com/LLaVA-VL/LLaVA-NeXT.git from llava.model.builder import load_pretrained_model from llava.mm_utils import get_model_name_from_path, process_images, tokenizer_image_token from llava.constants import IMAGE_TOKEN_INDEX, DEFAULT_IMAGE_TOKEN, DEFAULT_IM_START_TOKEN, DEFAULT_IM_END_TOKEN, IGNORE_INDEX from llava.conversation import conv_templates, SeparatorStyle from PIL import Image import requests import copy import torch import sys import warnings from decord import VideoReader, cpu import numpy as np import json from tqdm import tqdm import os warnings.filterwarnings("ignore") def load_video(video_path, max_frames_num,fps=1,force_sample=False): if max_frames_num == 0: return np.zeros((1, 336, 336, 3)) vr = VideoReader(video_path, ctx=cpu(0),num_threads=1) total_frame_num = len(vr) video_time = total_frame_num / vr.get_avg_fps() fps = round(vr.get_avg_fps()/fps) frame_idx = [i for i in range(0, len(vr), fps)] frame_time = [i/fps for i in frame_idx] if len(frame_idx) > max_frames_num or force_sample: sample_fps = max_frames_num uniform_sampled_frames = np.linspace(0, total_frame_num - 1, sample_fps, dtype=int) frame_idx = uniform_sampled_frames.tolist() frame_time = [i/vr.get_avg_fps() for i in frame_idx] frame_time = ",".join([f"{i:.2f}s" for i in frame_time]) spare_frames = vr.get_batch(frame_idx).asnumpy() # import pdb;pdb.set_trace() return spare_frames,frame_time,video_time pretrained = 'nkkbr/ViCA' model_name = "llava_qwen" device = "cuda" device_map = "auto" tokenizer, model, image_processor, max_length = load_pretrained_model(pretrained, None, model_name, torch_dtype="bfloat16", device_map=device_map) # Add any other thing you want to pass in llava_model_args model.eval() from datasets import load_dataset vsi_bench = load_dataset("nyu-visionx/VSI-Bench") vsi_bench = vsi_bench['test'] data_curr = vsi_bench[1000] video_path = f"[VIDEO PATH]" max_frames_num = 64 video,frame_time,video_time = load_video(video_path, max_frames_num, 1, force_sample=True) video = image_processor.preprocess(video, return_tensors="pt")["pixel_values"].cuda().to(torch.bfloat16) video = [video] conv_template = "qwen_1_5" # time_instruciton = f"The video lasts for {video_time:.2f} seconds, and {len(video[0])} frames are uniformly sampled from it.
