GPT-3 is a different model than gpt-oss and is therefore not an answer to the question.

I cannot stand using gpt-oss, but I miss some of the creative spark of GPT-3 davinci dearly.

Reading "davinci" brought a smile to my face. I had forgotten and this really took me back

Yes, The two couldn't be more different.

GPT-3 is probably one of the last models trained without synthetic data. Meanwhile gpt-oss is rumored to be only trained on synthetic data.

I also miss the 2020 GPT-3 based AI Dungeon fine tune.

I’ve found a very similar creative spark with Gemma4 base models. You’ll have to do old school prompting, but it’s kinda fun too.

At release, GPT-OSS was arguably a few generations behind the open frontier.

No? They were the frontier, or near it, at the time of release: https://artificialanalysis.ai/models/releases/gpt-oss-120b
