2.2B video-native VLM fitting in 5.2 GB VRAM with strong document and science understanding
HuggingFaceTB/SmolVLM2-2.2B-Instructmixpeek://image_extractor@v1/hf_smolvlm2_22b_v1Overview
SmolVLM2 is Hugging Face's lightweight multimodal model designed for efficient video, image, and text analysis at only 2.2B parameters. Built on a SigLIP vision encoder and SmolLM2 text decoder, it processes videos natively while fitting in just 5.2 GB of GPU RAM: small enough for consumer GPUs and edge devices.
On Mixpeek, SmolVLM2 enables cost-efficient visual captioning and understanding for high-volume video pipelines where larger VLMs would be prohibitively expensive. It scores 72.9% on OCRBench and 90% on ScienceQA, making it effective for document understanding and structured content analysis at a fraction of the compute cost of 7B+ models.
Architecture
SigLIP vision encoder with SmolLM2 text decoder in a Llama-style architecture. 2.2B parameters. Supports native video frame processing with temporal understanding. Only 5.2 GB GPU RAM for video inference. Apache 2.0 license.
Mixpeek SDK Integration
// No extractor parameter takes a Hugging Face model id (checked against
// GET /v1/discovery/extractors, which returns 13), so SmolVLM2-2.2B-Instruct runs
// on your side and the output is upserted through POST
// /v1/namespaces/{namespace_id}/documents/upsert. On Enterprise the other
// path is to upload the weights instead: POST /v1/namespaces/{id}/models
// accepts the huggingface format and a custom plugin loads them.
