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

  • It is a good terminal program and I like it for terminal operation with COM ports. It is a good all round terminal application that is easy to use and reasonably robust.
  • Met my needs. I was connecting to USB devices over serial terminal on Linux I used screen. This is sort of a hyperterminal.

Cons

  • 1) Every time I start logging to file, the target folder defaults back to its preset path. That is annoying and the older versions did not do that. 2) Setting the font size is seems buggy as size 7 is tiny small and cannot be read on the output screen but setting to size 8 is at super huge and cannot fit the screen width. This used to work beautifully on the older versions. Where even size 10 could be used for the same output and fitted. 3) On Win11 it often seems becomes inoperative if the USB/COM cable is pulled out. It then has to be closed and restarted. The older versions seemed to just say "disconnected " and work again when the cable is reconnected.
  • Lot of menus.
