Also, it seems like something more is needed to make gpt-3.5-turbo-16k work. The below prompt works with the regular model but not the 16k version.

Thank you so much for patching this! There were two PRs to address this problem and I merged the one based on Regex since it will be more future proof when new checkpoints come out. Closing this, but let me know if I missed something with the other PR. (the fix will hit PyPI on 0.0.63)
