Can someone please help me? I am new and I installed OpenClaw on my new Mac, which I bought for OpenClaw. I am currently using the Nemotron model by Nvidia and it has, I think, a 128K context limit but in my OpenClaw Chrome chat it is showing only 16K. Even if I give one prompt the context limit just gets almost full and I can't do anything about it. I tried fixing it but I am stuck and it is not fixed. I also told it to fix itself and asked it how to fix it but I am still unable to fix it. Please someone help me, I am stuck.
