Use-case guide · Summarisation

Should you pick RTX 4090 for summarisation?

RTX 4090 has 24 GB VRAM. Whether it's the right fit for summarisation depends on your model size, expected QPS, and budget. Below is what we're seeing in production.

VRAM + model fit

RTX 4090 fits models up to ~17B parameters in BF16 comfortably with room for KV-cache. For summarisation specifically, you'll want to leave headroom for context length growth.
