This is an interleaved merge of Xwin-longLORA-70b-rope8-32k-fp16 and Euryale-1.3-longLORA-70b-rope8-32k-fp16, using the same merge formula as alpindale's goliath-120b.
There is no additional fine-tuning. The resulting model seems to not be broken... you can test whether it is truly the original model + 32K capability (use linear rope scaling 8).
ChuckMcSneed did a benchmark here, indicating 30% degradation with 8x the context length.
A 6-bit EXL2 quantization is available here. More EXL2 quants here, thanks to aikitoria.
See this discussion for how the original 70B merges were created with longLORA.
