Qwen3-VL-8B-Abliterated-Caption-it-FP8

Qwen3-VL-8B-Abliterated-Caption-it-FP8 is an FP8-compressed variant built on top of prithivMLmods/Qwen3-VL-8B-Abliterated-Caption-it. This edition applies BF16 · FP8 (F8_E4M3) precision formats to significantly reduce memory usage and improve inference throughput while preserving the dense captioning strength and abliterated behavioral characteristics of the original 8B architecture. The base Qwen3-VL-8B-Abliterated-Caption-it model is a fine-tuned version of Qwen3-VL-8B-Instruct, tailored for Abliterated Captioning and uncensored image description. It is designed to generate highly detailed, descriptive captions across a broad range of visual categories, including complex, sensitive, or nuanced content, while supporting varying aspect ratios and resolutions.

FP8 (8-bit floating point) weight and activation quantization using hardware acceleration on GPUs – FP8 W8A8. Quantization W8A8 FP8-dynamic recipe – examples.

Key Highlights

• BF16 · FP8 (F8_E4M3) Compression: Transformer Engine based FP8 quantization reduces VRAM footprint and improves generation speed while maintaining caption quality.
• Abliterated Caption Fine-Tuning: Optimized for highly descriptive, dense caption generation with minimized refusal behavior.
• 8B Vision-Language Architecture: Balanced performance and deployment efficiency compared to larger parameter scales.
• High-Density Descriptions: Produces richly detailed captions suitable for dataset generation, metadata enrichment, archival systems, and accessibility pipelines.
• Dynamic Resolution Support: Handles diverse image sizes and aspect ratios effectively.
• Optimized Deployment: FP8 compression enables smoother deployment on Hopper and other compatible GPU architectures.
