There’s a couple models on huggingface that uses NTK/linear RoPE that you can play with. Vicuna and WizardLM both have a 16K context model. The biggest issue is that if you go to really high context, it sometimes does these weird repetitions. But to be fair, I only have tried the quantized models and 13B (highest I can run locally). Not sure if the repetition are an artifact of the rope or quantization or both.
