Can the NVIDIA GeForce RTX 5090 run Leanstral 119B-A6B?

51Fair quality (C) · 51 of 100: how capable the model is at Q2_K, whatever it runs on. Match score 57/100 (quality, fit, speed and memory use) sets the ranking.

Yes, but slowly (heavy RAM offload)

Slow (heavy RAM offload). At Q2_K it needs about 50.1 GB of 32.0 GB usable, with an estimated speed of 44.2 tok/s.

Best app to run it on the NVIDIA GeForce RTX 5090

On Windows

Docker Model Runner

Command line + local API · runs on llama.cpp, vLLM

  • Splits the model between GPU memory and system RAM, which this setup needs.
  • Handy if you already work in Docker.
docker model run hf.co/mistralai/Leanstral-2603

On Linux

How it’s rated

Quality 51Fair quality (C) · 51 of 100: how capable the model is at Q2_K, whatever it runs on. Match score 57/100 (quality, fit, speed and memory use) sets the ranking.
How capable the model itself is at Q2_K, from its editorial quality tier scaled by the quantization or precision. It’s the same on any hardware that runs this variant. Scale: A+ 85+ · A 70+ · B 55+ · C 40+ · D under 40.
Runs Slowheavy RAM offload
How well it runs on the NVIDIA GeForce RTX 5090: speed, capped by how well it fits in memory. Runs great: 30+ tokens/s (or near the image, video or decision speed target) · Runs well: 10+ tokens/s · Slow: 3+ tokens/s · Very slow: under 3 · Won’t run: doesn’t fit even with offload. A tight fit or RAM offload caps it at Runs well; heavy offload caps it at Slow.

Match score

To order lists, each result also gets a match score out of 100 from four parts. It favors the most capable model that still runs well.

Quick answers

How much memory does Leanstral 119B-A6B need on the RTX 5090 32GB?

At Q2_K it needs about 50.1 GB. The RTX 5090 32GB has 32.0 GB usable.

How fast is Leanstral 119B-A6B on the RTX 5090 32GB?

About 44.2 tok/s at Q2_K, an estimate from the hardware’s memory bandwidth and the size of the model.

Which quantization of Leanstral 119B-A6B should I use on the RTX 5090 32GB?

Q2_K. Of the versions that fit, it is the one that runs best; when two run equally well, the check prefers the higher-rated one.

Estimates come from published hardware specs and our open formulas, not from running the model on your machine. Real speed varies with runtime, drivers and settings. Numbers marked “Measured” come from a linked benchmark.
