Step3-VL-10B

Step3-VL-10B combines a 1.8B PE-lang visual encoder with a Qwen3-8B decoder. StepFun jointly trained the components on 1.2 trillion multimodal tokens before supervised and reinforcement learning.

Check the inference method behind a result

The card distinguishes sequential reasoning from PaCoRe. It also records a correction to comparison-model benchmark settings. A result from parallel reasoning includes extra inference work.StepFun Step3-VL-10B model card

Compare one attempt with parallel attempts

Practical guidance. For image extraction, begin with the normal inference path. Use parallel reasoning only when the task benefits from multiple interpretations. Keep both latency and the total generated tokens in your comparison.
