It's likely this is going to happen anyway, the new Mistral just dropped
and seems to perform roughly on par with llama3 and gpt4o, so the next wave
of fine tuned versions like dolphin are almost certainly coming soon.

OpenAI also has announced free fine tuning of gpt4o mini until late
September (up to 2m tokens/day) so it may be possible to fine tune around
some of its guardrails for a reasonable cost.
