Use-case guide · Reasoning / agentic

Should you pick A40 for reasoning / agentic?

A40 has 48 GB VRAM. Whether it's the right fit for reasoning / agentic depends on your model size, expected QPS, and budget. Below is what we're seeing in production.

VRAM + model fit

A40 fits models up to ~34B parameters in BF16 comfortably with room for KV-cache. For reasoning / agentic specifically, you'll want to leave headroom for context length growth.
