Skywork-R1V

LLMs Skywork Vision + text 1 build Open weights 36k dl/mo

Skywork-R1V is an open-weight language model from Skywork. Skywork-R1V-38B (BF16) weighs 76.8 GB; the smallest configuration that runs it is 4× RTX 4090 24 GB.

  • Skywork-R1V is a 38.4B parameter image-text-to-text model developed by Skywork.
  • It combines the InternViT-6B vision encoder with the DeepSeek-R1-Distill-Qwen-32B language model to perform visual chain-of-thought reasoning.
  • The model is designed for mathematical and scientific analysis of visual inputs and is released under the MIT license.
