Frequently asked
Quick answers to common questions
How much VRAM does SkyCaptioner-V1 need?
SkyCaptioner-V1 with 8.3B parameters needs approximately 5 GB at Q4_K_M quantization. Use our VRAM calculator for an exact estimate.
Is SkyCaptioner-V1 better than other Skywork models?
SkyCaptioner-V1 has 8.3B parameters with 128,000 context - a strong choice for video-understanding, vision.
What license is SkyCaptioner-V1 under?
SkyCaptioner-V1 is released under the apache-2.0 license, making it suitable for most commercial and personal projects.
What hardware runs SkyCaptioner-V1 well?
With 8.3B parameters, SkyCaptioner-V1 requires adequate VRAM. High-end GPUs like the RTX 4090 (24GB), RTX 5090 (32GB), or Mac Studio with unified memory are good options. Check our hardware directory for specific recommendations.
What is the best quantization for SkyCaptioner-V1?
Q4_K_M is the recommended sweet spot - ~98% of FP16 quality at ~27% of the size. Q5_K_M (~6 GB) is an option if you have spare VRAM. Use our VRAM calculator to compare.
How long can SkyCaptioner-V1's context window handle?
SkyCaptioner-V1 supports a 128,000-token context window - enough for very long documents, codebases, or multi-turn conversations. Real-world usable context may vary by implementation.
