Evaluate screenshot-assisted coding, interactive 3D code, visual Q&A and multi-step tools. Generated code still needs a runtime and acceptance checks.
How to evaluate it
Test text first, then add screenshots and tool results while measuring visual understanding, coding quality, and per-task cost.
What to check before integration
Use the exact LongCat-2.5 ID. The vendor has released the non-Preview version with up to 256K output. The gateway reference lists 1M context and vision; verify actual output limits and availability with the endpoint in use.
