Step 1V 32K is StepFun's vision-language model offering a 32,000-token context window for handling longer documents and multi-turn conversations that include image inputs. StepFun, a Shanghai-based AI lab, built Step 1V to process both text and visual information within a single unified model.
The model suits tasks where images must be understood alongside extended textual context — such as analyzing charts with accompanying reports, document Q&A with embedded diagrams, or multi-image comparisons. Its context length advantage over smaller vision models makes it practical for document-heavy multimodal workflows.
