About
Solar Pro 4 is an agentic AI model built to carry real work to the finish: reading documents, running tools, producing deliverables, and stopping when the evidence runs out. It targets longer, more complex workloads that move across multiple documents, execute tasks in a terminal, and chain tool calls over many steps. The model supports a 512K context window with up to 128K output tokens, allowing agents to load contracts, reports, and data files into a single session without splitting them. It handles English, Korean, and Japanese for both input and output, while adjustable reasoning effort lets users choose deeper analysis or faster, real-time interaction. Solar Pro 4 is designed to stay accurate through long documents, multi-turn tool use, and terminal tasks, and to preserve values and conclusions across sequential deliverables such as Excel workbooks, reports, and slide decks.

About
Step 5 Preview is StepFun’s flagship model for agentic work, designed for real-world tasks across software engineering and professional knowledge work, with particular strength in finance. It natively supports text, image, and video input and provides a 1M-token context window, enabling tasks that require large amounts of information, tool calls, and continuous progress toward a deliverable. The model can analyze long documents, multiple source materials, and conversation history for cross-document question answering and research organization. For programming and software engineering, it works across multiple languages and can support troubleshooting, code changes, verification, and test creation. Its multi-step agent capabilities let applications provide tools for retrieving information, processing documents, conducting deep research, and producing analytical reports. Multimodal understanding combines images, video, and text for chart analysis, screenshot question answering, etc.
