Is there an easy way to use the March 14th model ChatGPT-4 model?

Like many people, I strongly suspected that OpenAI lobotomized the May 24th GPT-4 model (perhaps to speed up response times or save on computing resources). Recently, I've confirmed this by testing a few prompts against the original "gpt-4-0314" (March 14th) model in the OpenAI playground where it still responds beautifully.

My question is: Do any of the myriad of bring-your-own-API-key alternative ChatGPT frontends allow the user to select the "gpt-4-0314" model?

I've already tried a couple (ChatBotUI & TypingMind), but neither seem to offer this feature.
