Today Databricks announced [0] 6b parameter model from EleutherAI finetuned on Alpaca dataset. According to their CEO[1], training took 3 hours, and costed $30. They didn't release any details on how it was trained, but likely with LoRa.
I haven't done any formal tests on this yet, but with llama-13b, the overall structure of its responses definitely becomes much more ChatGPT-like. It would be very interesting to see how the 65B model performs.

Perhaps it’s in the paper…
