Covers installation from scratch, downloading the LTX 2.3 model (~40GB), generating videos from text prompts, and animating existing images using the image-to-video workflow — all without API keys, subscriptions, or usage fees. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How can I generate AI videos for free on my own PC without a subscription? ComfyUI, a free open-source application, lets you run AI video models directly on your own PC with no per-video charges once installed. Install the desktop version, download a text-to-video model such as LTX 2.3 (around 40 gigabytes), enter a text prompt, and click Run to generate a video locally without API keys or usage credits. _daily.dev surfaces guides like this for developers experimenting with local AI video generation setups._ ### Which free video generation model works best in ComfyUI for text-to-video on an RTX graphics card? LTX 2.3 is recommended because it runs on a wide range of NVIDIA RTX graphics cards, generates results quickly, and produces high-quality output. Other free options available in ComfyUI include WAN 2.2, Hunyuan, Kandinsky, and SVD, all filterable by selecting models that run locally rather than through paid cloud services. _developers comparing local AI video models can track option tradeoffs on daily.dev before committing hardware resources._ ## Similar posts on daily.dev - [How to Get Started With Visual Generative AI on NVIDIA RTX PCs](https://daily.dev/posts/how-to-get-started-with-visual-generative-ai-on-nvidia-rtx-pcs-9apbreq9m) · NVIDIA · 0 upvotes · 0 comments - [How to Build, Run, and Scale High-Quality Creator Workflows in ComfyUI](https://daily.dev/posts/how-to-build-run-and-scale-high-quality-creator-workflows-in-comfyui-ivevkjcrg) · NVIDIA Developer · 1 upvotes · 0 comments - [NVIDIA and ComfyUI Streamline Local AI Video Generation for Game Developers and Creators at GDC](https://daily.dev/posts/nvidia-and-comfyui-streamline-local-ai-video-generation-for-game-developers-and-creators-at-gdc-mdw9odwdf) · NVIDIA · 0 upvotes · 0 comments --- Tags: [#ai-video-generation](https://daily.dev/tags/ai-video-generation), [#text-to-video](https://daily.dev/tags/text-to-video) [View this post on daily.dev](https://daily.dev/posts/how-to-generate-ai-videos-for-free-with-comfyui-step-by-step-tutorial--h96qykvba) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"How to Generate AI Videos for FREE with ComfyUI (Step-by-Step Tutorial)","url":"https://daily.dev/posts/how-to-generate-ai-videos-for-free-with-comfyui-step-by-step-tutorial--h96qykvba","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/how-to-generate-ai-videos-for-free-with-comfyui-step-by-step-tutorial--h96qykvba"},"datePublished":"2026-07-16T00:43:28.639Z","dateModified":"2026-09-13T19:52:09.329Z","description":"A beginner-friendly walkthrough for generating AI videos locally using ComfyUI Desktop on a Windows PC with an NVIDIA RTX GPU.
