Step3 VL 10B
Step3 VL 10B is StepFun’s compact vision-language reasoning model, combining an approximately 1.8B visual encoder with a language backbone. It targets visual STEM reasoning and language generation from images. PaCoRe mode combines evidence from sixteen parallel rollouts, so its scores should be separated from ordinary single-model sampling. Apache-licensed base and post-trained checkpoints support research and local evaluation. The full weight footprint, context length, and selected reasoning mode affect deployment cost and latency.
