Hi, Hoarder's developer here.
I highly recommend against the `gpt-4` model. `gpt-4` costs $30 / 1M tokens which is extremely expensive. Hoarder defaults to `gpt-3.5-turbo-0125` for text which costs $0.5 / 1M tokens (notice the huge difference!). If you want `gpt-4` level of inference, go for `gpt-4o` which is $5 / 1M tokens still much cheaper than the `gpt-4` model.
