Their hardware – an NVIDIA GeForce RTX 3060 with **6 GB** of VRAM – could not load the model using standard PyTorch, resulting in a “CUDA Out of Memory” error.\n\nTo bypass the memory wall they built **lowvram**, an open‑source wrapper that intercepts CUDA allocation calls and tricks the driver into using system RAM when VRAM runs out. With lowvram the same YuE2 code produces **43.1 tokens per second** (range 41.0‑46.0), about **95 %** of the oracle speed that runs from device memory. By contrast, the standard Accelerate method reaches only **1.9 tokens per second**, making lowvram roughly **23 ×** faster. The tool also enables other models such as Llama‑TTS with Qwen3‑TTS‑12Hz‑1.7B‑Base‑Q80, which would otherwise fail immediately.\n\nLowvram is not a universal fix; it trades raw speed for functionality and may break with driver or library updates. Still, for developers and hobbyists with limited GPU resources, a single line of code can turn an otherwise unusable model into a workable prototype.","keyPoints":["lowvram intercepts CUDA calls, allowing 6 GB GPUs to run models that need 24 GB VRAM","YuE2 runs at 43.1 tokens/s with lowvram, 95 % of the full‑memory oracle speed","Accelerate reaches only 1.9 tokens/s on the same hardware, making lowvram ~23× faster"],"whyItMatters":"Enabling large AI models on consumer‑grade GPUs lowers the cost barrier for experimentation and prototyping, expanding access for developers and small teams.","category":{"slug":"agents","name":"Agents & Tools","url":"https://digestai.news/category/agents"},"entities":{"companies":["NVIDIA","GitHub"],"models":["YuE2","Llama-TTS","Qwen3-TTS-12Hz-1.7B-Base-Q80"],"people":[]},"firstPublishedAt":"2026-11-06T14:50:02Z","updatedAt":"2026-11-06T14:50:02Z","sourceCount":1,"hasPrimarySource":false,"sources":[{"outlet":"soarhen.com","title":"lowvram: How I ran large AI models in low VRAM GPUs","url":"https://soarhen.com/how-run-ai-in-low-vram","publishedAt":"2026-11-06T14:50:02Z","type":"press","primary":false,"lead":true}],"sourceNotes":null,"discussions":[{"site":"Reddit","url":"https://www.reddit.com/r/LocalLLaMA/comments/1xpense/lowvram_how_i_ran_large_ai_models_in_low_vram_gpus/","points":null}],"thread":null,"cite":{"text":"Digest AI, \"Lowvram lets 6 GB GPUs run large models like YuE2 with reduced speed\", 6 November 2026, https://digestai.news/story/lowvram-lets-6-gb-gpus-run-large-models-like-yue2-with-reduced-speed","publisher":"Digest AI","title":"Lowvram lets 6 GB GPUs run large models like YuE2 with reduced speed","datePublished":"2026-11-06T14:50:02Z","url":"https://digestai.news/story/lowvram-lets-6-gb-gpus-run-large-models-like-yue2-with-reduced-speed"},"generatedBy":"Written by Digest AI's editorial model from the linked sources; the sources are the record.","license":"Headlines, digests and key points are written by Digest AI and may be quoted with a link to the story page.
