Model overview
**VisionPsy-Nano-460M-Flash-GGUFs** provides GGUF weights of VisionPsy-Nano-460M-Flash for fast, fully on-device multimodal inference with our patched **llama.cpp** fork (not stock upstream). Flash is the **efficiency-optimized** sibling of VisionPsy-Nano-460M: same ~460M nanoVLM architecture, but it processes each image with **far fewer visual tokens (as few as 64 at 512x512)**, so it responds an order of magnitude faster on real phones while giving up only a small amount of accuracy. Unquantized **FP32** and **BF16 GGUFs** are included alongside a family of quantization formats, from near-lossless **8-bit** through a high-quality **5-bit** option down to ultra-compact **3-bit**. All sub-8-bit variants (except the legacy `Q4_0`) use **importance-matrix (imatrix) calibration**. If VisionPsy-Nano-460M-GGUF is our best-quality ~0.5B GGUF, **Flash-GGUF is the one you ship when time-to-first-token, battery, and RAM are the binding constraints.** > Each GGUF is a **vision-language** model: alongside the text weights (`*.gguf`) you also need the > multimodal projector (`mmproj-*.gguf`, the SigLIP2 vision encoder) to run image inputs. See > Usage.
Key features

Limitations & considerations
Sources are insufficient to establish specific limitations. Verify task performance, latency, data policies, licensing and version lifecycle.
Source prices & cost analysis
Prices vary by channel, region and configuration. Channel quotes are listed independently and are not treated as a single official provider price.

Do open weights permit free commercial use?
Not necessarily. Check the version license, commercial conditions and usage policies. Self-hosting incurs compute and maintenance costs.
Are these real-time billing prices?
These are timestamped source snapshots, not live billing prices. Check the channel for current versions, regions, discounts and billing methods.
