Summarizing https://www.reddit.com/r/LocalLLaMA/comments/15rxlrq/openorcaplatypus_is_out_a_13b_that_surpasses/
Here's my try:
We're releasing OpenOrca-Platypus2-13B, a new large language model that is a merge of OpenOrcaxOpenChat Preview2 and Platypus2. It's available on HuggingFace now, and we have the model running unquantized for you to play with in your browser too.
