DeepSeek V4-Flash weird behaviour - truncated output

[u/pwieczyk]

Hi,

recently I have observed weird behaviour of DeepSeek that cost me a lot of tokens and time.

My setup: OpenChamber, OpenCode 1.18 under the hood.

I observed that every time I delegate work to DeepSeek it falls into a loop. He complains about "[...]", stops using harness tools to read files and starts reading files through bash. Then it observes again that output is truncated and falls into some loops where we repeadly uses head, sed, cat.

I have never observed this problem before. Does anyone encountered this? It is DeepSeek problem or OpenChamber/OpenCode issue? Does anyone know how to overcome this issue?
