📜 Table of Contents
Text-to-video was a closed API in 2025; by 2026 the open models are good enough for real projects. Here is the current landscape.
The Contenders
Open-Sora (29,251 stars) democratizes efficient video generation - shorter clips, lower hardware requirements, active community. HunyuanVideo (12,415 stars) from Tencent focuses on quality and longer coherent motion. CogVideo (12,940 stars) from THUDM has strong community support and Chinese-language understanding. All are open weights.
Hardware Reality
You need a serious GPU: 24GB+ VRAM for reasonable generation times, or cloud GPUs (runpod-style rental) for bigger jobs. Output quality varies wildly by prompt - motion coherence is the weak point. Short clips (2-5 seconds) look best; extend by chaining.
FAQ
Q: Can I run these on my laptop?
A: Not realistically - you need a workstation GPU or cloud rental. Some models offer quantization for smaller cards.
Q: What is the quality ceiling?
A: Impressive for short clips, but faces and complex motion still break. Treat outputs as drafts for human editing.
