Los 8 mejores open source AI video model para cada caso de uso

Morphic

Run open models like Wan and LTX, plus flagship closed ones like Veo and Kling, in one visual Canvas with no GPU setup.

  • Open source video models are powerful, but running them means a capable GPU, CUDA drivers, a ComfyUI or diffusers setup, and time. Morphic hosts open models like Wan and LTX so you can generate from a prompt without any of that.
  • The same workspace runs the flagship closed models too, Veo, Kling, Seedance, Hailuo, and Vidu, so you can compare an open model against a closed one on the exact same shot before you commit.
  • Clips land on a free-flowing visual Canvas and stay live. Line the selects up on Compose, the built-in timeline, add generated voiceover and music, and export the finished cut without leaving the workspace.
  • To be clear: Morphic is a hosted platform, not an open source project. If your requirement is downloading weights to self-host or fine-tune, run the open models directly. If your requirement is generating with them fast, this removes the setup.

#2

Wan (Alibaba)

Alibaba's open video model family, widely regarded as the leading open weights for quality and motion.

Wan is the model most self-hosters reach for first. Released under a permissive license with open weights, it delivers strong text-to-video and image-to-video quality that closes much of the gap to closed models, and its motion holds up on demanding prompts. A large community means abundant ComfyUI nodes, LoRAs, and fine-tunes. The heavier variants demand a serious GPU and VRAM, and getting the best results still takes tuning of samplers and settings that a hosted service hides.

Ideal para: Best overall open weights quality
Ventajas
  • Top-tier open quality on text and image-to-video
  • Large community with LoRAs and tooling
Desventajas
  • Heavier variants need a serious GPU and VRAM
  • Best results take sampler and setting tuning
#3

LTX Video (Lightricks)

An open model from Lightricks tuned for speed, capable of near real-time generation on consumer hardware.

LTX Video is built for efficiency. It generates markedly faster than most open models and runs on more modest GPUs, which makes it a favorite for rapid iteration and for creators without a data-center card. The speed suits previews, drafts, and high-volume experimentation. The trade is that raw fidelity and the hardest motion trail the heaviest models, so it is often used to iterate quickly and then finish elsewhere. Open weights and an active ecosystem keep it accessible.

Ideal para: Fast generation on consumer GPUs
Ventajas
  • Fast enough for rapid iteration
  • Runs on more modest consumer GPUs
Desventajas
  • Raw fidelity trails the heaviest models
  • Hardest motion suits larger models
#4

HunyuanVideo (Tencent)

Tencent's large open video model, known for cinematic quality and strong prompt adherence.

HunyuanVideo is one of the largest open models available, and it shows in the output: cinematic, detailed shots with good prompt adherence that rival closed offerings on the right prompt. Open weights and a growing ecosystem of adapters make it a serious option for teams that can host it. The size is the cost, though: it demands substantial VRAM and compute, generation is slower than lighter models, and the setup is more involved than a plug-and-play tool.

Ideal para: Cinematic quality from open weights
Ventajas
  • Cinematic detail that rivals closed models
  • Open weights with a growing adapter ecosystem
Desventajas
  • Demands substantial VRAM and compute
  • Slower generation and more involved setup
#5

Mochi 1 (Genmo)

Genmo's open model praised for fluid, high-fidelity motion under a permissive license.

Mochi 1 earned attention for motion quality. It produces smooth, physically believable movement that stands out among open models, released under a permissive Apache license that is friendly to commercial use. For creators who care most about how a shot moves, it is a strong pick. It centers on text-to-video, so image-to-video and some control features are lighter than rivals, and the full model needs capable hardware to run at its best resolution and length.

Ideal para: Fluid motion under a permissive license
Ventajas
  • Smooth, believable motion for an open model
  • Permissive license friendly to commercial use
Desventajas
  • Image-to-video and control features lighter
  • Full model needs capable hardware
#6

CogVideoX (Zhipu / THUDM)

An accessible open model line with variants that run on relatively modest GPUs.

CogVideoX is a practical entry point into open video generation. It ships in multiple sizes, including variants light enough to run on consumer cards, and both text-to-video and image-to-video are supported with solid, dependable results. Strong documentation and diffusers integration lower the setup barrier. It does not top the quality charts against the largest models, and the finest detail and longest clips are better served elsewhere, but the accessibility and reliability are the draw.

Ideal para: An accessible starting point for self-hosting
Ventajas
  • Runs on relatively modest GPUs
  • Good docs and diffusers integration
Desventajas
  • Does not top quality against the largest models
  • Finest detail and longest clips suit bigger models
#7

Stable Video Diffusion (Stability AI)

Stability AI's image-to-video model, one of the earliest widely-adopted open releases.

Stable Video Diffusion helped open the category and remains widely integrated across open tooling. It animates a still image into a short clip and benefits from the enormous Stable Diffusion ecosystem, so nodes, guides, and community support are everywhere. It is showing its age against 2026 models: clips are short, control is limited, and motion is simpler than newer releases. For image-to-video basics and learning the pipeline, it is still a reasonable, well-supported starting point.

Ideal para: Basic image-to-video with broad support
Ventajas
  • Widely supported across the open ecosystem
  • Simple image-to-video that is easy to run
Desventajas
  • Short clips and limited control
  • Motion simpler than newer 2026 models
#8

Open-Sora (HPC-AI Tech)

A fully open project that reproduces a Sora-style pipeline, transparent end to end.

Open-Sora is aimed at the research and tinkering crowd. It open-sources not just weights but the training pipeline and data recipe, so the whole stack is transparent and reproducible, which is valuable for teams that want to understand or extend the model rather than just call it. That openness is the point. The trade is that out-of-the-box quality trails the polished flagship open models, and it expects more comfort with training code and infrastructure than a ready-to-use release.

Ideal para: Full transparency and research use
Ventajas
  • Entire stack is transparent and reproducible
  • Ideal for extending and researching the model
Desventajas
  • Out-of-the-box quality trails flagship open models
  • Expects comfort with training infrastructure

¿Qué es un modelo de video con IA de código abierto?

Un modelo de video con IA de código abierto (open source) es un modelo de generación cuyos pesos están publicados para que cualquiera los descargue, los corra y, casi siempre, los ajuste a su gusto. En vez de llamar a la API de una empresa, tienes el modelo mismo y lo corres en tu propio hardware o en una GPU en la nube que alquilas. La categoría va de modelos grandes y cinematográficos, como HunyuanVideo, hasta otros livianos, como LTX Video, pensados para correr en una tarjeta de consumo.

El atractivo es el control. Con los pesos abiertos no pagas por cada generación, puedes ajustar el modelo con tu propio material, tus datos se mantienen privados y tienes libertad para integrarlo en tu propio pipeline. El costo es que tú administras la infraestructura y la configuración: es un compromiso técnico real, no un simple registro.

Modelos de video con IA de código abierto frente a los cerrados

Los modelos cerrados, como Veo, Kling y Sora, funcionan como un servicio alojado: envías un prompt, ellos corren el modelo en su propio hardware y tú recibes el clip. Suelen liderar en calidad máxima y no exigen ninguna configuración, al precio de pagar por uso, tener límites de consumo y no tocar los pesos que hay debajo. Tu material pasa por sus servidores, y construyes solo con lo que ellos deciden exponer.

Los modelos de código abierto invierten esa lógica. Tienes los pesos, así que puedes correr todo sin conexión, ajustar el modelo, cuidar tus datos y pagar solo por el cómputo que usas, a cambio de administrar tú mismo las GPU, los drivers y el pipeline de generación. Ninguno de los dos es mejor por naturaleza: un equipo que necesita personalización, privacidad o control de costos a gran escala se inclina por lo abierto, y uno que busca el mejor resultado sin ninguna configuración se inclina por lo cerrado. Muchos estudios independientes de la región usan los dos, según el proyecto.

Cómo funcionan los modelos de video con IA de código abierto

Estos modelos son transformers de difusión: el modelo parte de ruido y lo refina paso a paso, guiado por tu prompt, hasta llegar a una secuencia de cuadros temporalmente consistente. Para correr uno, cargas los pesos en un framework como diffusers o en un grafo de ComfyUI, le das suficiente VRAM, y ajustas samplers, pasos y resolución según la calidad y la velocidad que buscas. Para ajustarlo a tu gusto, sumas un LoRA o una pasada de entrenamiento completa con tus propios datos.

Morphic llega a esos mismos modelos por otro camino. En vez de alojarlos tú mismo, eliges un modelo abierto como Wan o LTX desde el navegador y generas desde un prompt o una imagen fija, sin GPU, sin drivers y sin instalar nada. El clip aparece en el Canvas junto a modelos cerrados como Veo y Kling, así que los comparas sobre la misma toma, y después armas la secuencia en Compose, la línea de tiempo integrada, sin salir del espacio de trabajo.

Preguntas frecuentes

What is the best open source AI video model in 2026?
Wan is the common answer for overall open weights quality, with HunyuanVideo close behind on cinematic detail and Mochi 1 leading on motion. The best choice depends on your GPU and license needs. If you would rather skip the hardware, Morphic runs Wan and LTX hosted, next to closed models like Veo and Kling.
What hardware do I need to run open source video models?
It varies widely. Lighter models like LTX Video and smaller CogVideoX variants run on consumer GPUs, while HunyuanVideo and heavier Wan variants want a data-center card with lots of VRAM. If you do not want to manage hardware, Morphic runs the open models in the cloud with no setup.
Are open source video models free to use commercially?
Often, but check the license per model. Mochi 1 and Wan ship under permissive licenses friendly to commercial use, while some releases carry restrictions. Always read the specific license before shipping commercial work, since terms differ across projects and can change between versions.
Is Morphic an open source video model?
No. Morphic is a hosted platform, not an open source model, and you cannot download its weights or self-host it. What it does is run open models like Wan and LTX, alongside flagship closed models, so you can generate with them fast without any GPU or setup. For self-hosting or fine-tuning, run the open models directly.
Can I fine-tune an open source video model?
Yes, that is a key reason to use one. Open weights let you train LoRAs or fine-tune on your own footage, and models like Wan have large communities sharing adapters. This needs your own hardware and ML setup; a hosted platform like Morphic trades that flexibility for zero-setup generation.
Open source vs closed video models: which is better?
Closed models like Veo and Kling still lead on peak quality and ease, while open models win on control, cost at scale, privacy, and customization. Many teams use both. On Morphic you can compare an open model against a closed one on the same prompt before deciding which fits the shot.
