Memory is the weights at that precision plus 20% for the runtime and a short context; a long context needs more. Prices are the lowest on-demand hourly rates in the SAVRN Index, read Sep 18, 2026.

SAVRN's Notes on Qwen3.5-0.8B

Half a gigabyte of memory runs Qwen3.5-0.8B at 4-bit; 16-bit needs 2.1 GB and 8-bit 1.0 GB. It takes images and text in and returns text, with 873 million parameters and a 262,144-token context, and the evaluations the file reports, ScreenSpot-Pro and ExtractBench among them, point at screen and extraction work. The cheapest place to put it is a 192 GB MI300X at $1.85 an hour on demand, where dozens of copies fit, so the hourly rate is the cost that matters, not memory.

The file traces it to Qwen/Qwen3.5-0.8B-Base, and Apache License 2.0 allows commercial use, modification and redistribution, with notices kept and significant changes stated, so a tuned variant of your own is within the terms. Check the long-context path before leaning on the 262,144-token window: the ExtractBench figures in the file fall from 46.63 mean to 26.98 medium to 6.65 long, all third-party reported.

PaddleOCR-VL-1.5: Towards a Multi-Task 0.9B VLM for Robust In-the-Wild Document Parsing PaddleOCR-VL-1.5 is an advanced next-generation model of PaddleOCR-VL, achieving a new state-of-the-art accuracy of 94.5% on OmniDocBench v1.5. To rigorously evaluate robustness against real-world physical distortions—including scanning artifacts, skew, warping, screen photography, and illumination—we propose the Real5-OmniDocBench benchmark. Experimental results demonstrate that this enhanced model attains SOTA performance on the newly curated benchmark. Furthermore, we extend the model’s capabilities by incorporating seal recognition and text spotting tasks, while remaining a 0.9B ultra-compact VLM…

SmolVLM2-500M-Video is a lightweight multimodal model designed to analyze video content. The model processes videos, images, and text inputs to generate text outputs - whether answering questions about media files, comparing visual content, or transcribing text from images. Despite its compact size, requiring only 1.8GB of GPU RAM for video inference, it delivers robust performance on complex multimodal tasks. This efficiency makes it particularly well-suited for on-device applications where computational resources may be limited. SmolVLM2 can be used for inference on multimodal (video / image / text) tasks where the input consists of text queries along with video or one or more images.…

This Hub repository contains a HuggingFace's transformers implementation of Florence-2 model from Microsoft. Florence-2 is an advanced vision foundation model that uses a prompt-based approach to handle a wide range of vision and vision-language tasks. Florence-2 can interpret simple text prompts to perform tasks like captioning, object detection, and segmentation. It leverages our FLD-5B dataset, containing 5.4 billion annotations across 126 million images, to master multi-task learning. The model's sequence-to-sequence architecture enables it to excel in both zero-shot and fine-tuned settings, proving to be a competitive vision foundation model.
