A: Based on the specifications:
Llama 3.1-8B: Requires at least 8GB of VRAM, which is fully supported by our Medium, Large, Large Pro, and Ultra plans.
Llama 3.1-70B: Requires approximately 70-75GB of VRAM. Unfortunately, this exceeds the capacity of even our Ultra plan, which provides 48GB VRAM.
Llama 3.1-405B: Requires extremely high VRAM and hardware resources, around 400-450GB VRAM, which is currently beyond the scope of what we offer.
So, the best Llama 3.1 version that our Ultra plan can support is the Llama 3.1-8B model.
