Questions
What is the best free AI model for the RTX 5080?
No voted model fits entirely in 16 GB at 4-bit. Small models without Arena votes do, and larger ones run with help from system RAM, more slowly.
How big a model can the RTX 5080 run?
About 23 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 5080 good for local LLMs?
It has 16 GB of memory and 960 GB/s of bandwidth. Memory decides which models fit; bandwidth decides how fast they write. With 16 GB it runs models up to about 20 B fully on the GPU; 27–32 B models need help from system RAM.
