Use-case guide · Long context

Should you pick TPU v4 for long context?

TPU v4 has 32 GB VRAM. Whether it's the right fit for long context depends on your model size, expected QPS, and budget. Below is what we're seeing in production.

VRAM + model fit

TPU v4 fits models up to ~22B parameters in BF16 comfortably with room for KV-cache. For long context specifically, you'll want to leave headroom for context length growth.
