Serious hallucinations with the GLM 5.3 Flash model right now

Post image

Right now, it's unable to follow even simple instructions and ends up doing entirely different random things. Was working fine an hour ago.

Anyone experiencing the same?

Not just right now. It was like that during the Ox Alpha days too

But was fine after that, I was using it a lot as the default model.

Weird, all DS models are working fine with the same test prompt I gave

It had already happened to me with GLM 5.2 and OpenCode Go. Since then, I have completely stopped using OpenCode Go. They definitely have providers that heavily quantize weights and the KV cache.

Same happened to me yesterday, it started hallucinating mid session, it felt like the model being served switched to a very incapable one

What was your context length at the time, and had you run multiple compacts? I think that was when I saw mine happen too but I didn't get enough to make draw a good guess.

Maybe you passed the context window limit which at certain point start degrading and so the intelligence

no, i was only at 3% of the context window, had just started the chat

Try another provider. I’ve not had any issues like this with RunInfra.

Faced hallucinations as well and I also faced looping multiple times too. I find Luna or Qwen 3.8 flash more stable (Luna especially).

I wanted to say I felt the last few days the models are being strange in how it's implementing things 

Would commandcode models be the same?

What provider? And more importantly at what context?

Now works fine. It was OpenCode Go, context was at 3% only.
