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.

Pros & Cons from Real Users

Pros

  • For my scientific conference presentation, I received surprisingly high-quality and comprehensive assistance. I was provided with excellent examples regarding the content of my slides. The number of slides was perfectly tailored to the time allotted for the presentation—a very smart approach.
  • I like Z.Ai because it is full power, there is no half-heartedness in writing code compared to others.

Cons

  • So far, I haven't found any flaws. Perhaps after the entire process is complete, I might identify something that could be improved.
  • Still haven't found any weaknesses because up to now I have been helped a lot in making the program.
