Ask HN: Has anyone used a Tenstorrent Grayskull card with an LLM?

I was curious, considering the price of GPUs, if anyone had tried using a Tenstorrent Grayskull card with something like Llama 2, or am I completely misunderstanding the use case for Tenstorrent cards? If the latter is the case, can anyone provide a link to somewhat concise summary of what all the differing "AI" hardware is used for?
