It's odd. Running inference on this (and other models in its class) and I keep running into a "repeating token" situation with moderate-to-long context windows.
It feels almost as if, during inference, the model hits some format of local minimum that it careens around, and while temperature seems to affect this - it doesn't really fix it.

- gpderetta 3y agoThat's seems a perfect story to put a little child to bed :D. I have used a similar recursive story in the past. My son still jokes about it.
- fho 3y agoThere actually was a podcast around that concept when (I think) GPT2 was current. Basically one generated story per day. Absurd in places.
- polygamous_bat 3y agoFrom what I heard through the grapevine, OLMo is not nearly the best model for its size or compute budget. Apparently something didn’t quite go right and AI2 didn’t have the money to train until they got it right.
