Questions
What is the best free AI model for the RTX 5090?
Gemma 4 31B (Arena score 1443) is the highest-voted open model that fits entirely in 32 GB of video memory at 4-bit, writing about 62 tokens per second.
How big a model can the RTX 5090 run?
About 48 billion parameters for a dense model at 4-bit with an 8K context, fully on the GPU. Mixture-of-experts models can be bigger, and with 64 GB of system RAM larger models still run, more slowly.
Is the RTX 5090 good for local LLMs?
It has 32 GB of memory and 1792 GB/s of bandwidth. Memory decides which models fit; bandwidth decides how fast they write. With 24 GB or more it runs 27–32 B models, the sweet spot of quality for home use.
