(8GB → 24GB VRAM)", "summary": "As of mid-2026, open-source AI video models like Wan 2.2, Open-Sora 2.0, and HunyuanVideo can run on consumer GPUs with 8GB to 24GB VRAM, generating 5-20 second clips at 720p or 1080p. However, leaderboards and aggregator sites often misrepresent VRAM requirements and model performance, making it difficult to choose the best self-hosted option versus commercial services like Runway.", "body_md": "Member-only story\n\n# What’s the Best Open-Source AI Video Model You Can Actually Run? (8GB → 24GB VRAM)\n\n*The honest case for self-hosting in 2026 — and when paying Runway still wins.*\n\nRead the article for free\n\n[.]here\n\nThe graphics card in your desk is doing a lot less than it could. Most of the time it sits idle. When you do use it, you’re running games or maybe a local language model. As of mid-2026, that same card can also generate video — five to twenty seconds at a time, in 720p or 1080p depending on which model you pick and how patient you are with render times.\n\nSearch ‘**best open-source AI video model 2026**’ and the first six results disagree on which model is best, which numbers to trust, and which ones will fit in 12GB of VRAM.\n\n## The landscape is louder than it is honest\n\nThe current leaderboards and aggregator sites paint a picture of an open-source ecosystem that has already surpassed commercial APIs.\n\nTheir headline numbers: **Wan 2.2** at 84.7% on VBench, **Open-Sora 2.0** closing the Sora gap to 0.69%, **HunyuanVideo’s** 96.4% visual quality on a 4090.\n\nThese aggregators scrape GitHub READMEs, mix up model versions, hallucinate VRAM requirements, and present it all as a buying guide.
