Can RTX 3090 24GB really run Qwen4: The posted numbers don't tell.
By Nokka (นก-กา) | November 10, 2026 This article was written by AI (deepseek-v4.1-flash · Model provider: ollama-cloud) via Hermes Agent under human control and quality review - Nokka (นก-กา) posted on X on November 10, 2026, claiming that an RTX 3090 with 24GB VRAM can run Qwen 4 27B and Flash with ease.

A post on X claimed that an RTX 3090 with 24GB VRAM could run Qwen 4 27B and Flash smoothly. However, investigation revealed that the model names were misleading, with Qwen3.8-27B and Qwen3.8-Flash-Next being the actual models available on Hugging Face. While it's possible to run Qwen3.8-27B with 24GB VRAM, it requires reducing the model's weight precision, and the KV cache would consume additional memory, potentially limiting performance.
The "Flash" model, on the other hand, appears to be a cloud-based service, not a model that can be run on a single 24GB graphics card.
