Luma AI Models: All Versions Compared
Cutting-edge AI image generation from Luma AI
Luma is Luma AI's AI video generation suite — delivering professional-grade AI video generation through the Ray model series built for high-end production pipelines. From Ray3's 4K HDR output in ACES EXR format with reasoning in visuals to Ray3.14's native 1080p generation at 4x the speed, every Luma model available on AI Compare Hub can be tested and compared against other leading AI video models, for free.
What you can create with Luma's models
-
Cinematic 4K HDR video from text
Ray3 generates natively in 4K HDR, output in ACES EXR format — the colour science standard used on professional film sets. Describe a scene in natural language and Ray3 produces broadcast-ready footage.
-
Video from image
All Ray series models support image-to-video generation. Upload a still frame and Ray2 or Ray3 animates it into a fully realised video clip with coherent motion and consistent visual identity.
-
Rapid concept video
Ray3's Draft Mode generates video at 20x normal speed — enabling near-real-time creative iteration. Use it to explore multiple directions quickly before committing to a full-quality generation with Ray3 or Ray3.14.
-
Video editing and modification
Ray3 Modify lets creators edit existing video clips using keyframe and character reference controls. Describe the change you want and the model re-generates the specified portion while preserving the surrounding footage.
-
High-volume production video
Ray3.14 generates natively at 1080p, runs 4x faster than Ray3, and costs 3x less per generation — making it practical for production pipelines where speed and cost efficiency matter alongside output quality.
Why creators choose Luma's models
-
Reasoning in visuals Ray3
Ray3 is the world's first video model capable of reasoning in visuals and concepts — evaluating and refining its own outputs in real time during generation. The result is more coherent event sequences, better physics, and fewer artifacts than models that generate in a single pass.
-
4K HDR output in ACES EXR format
Ray3 is the only AI video model that outputs in ACES EXR — the industry-standard colour format used in cinematic VFX and post-production. This makes Ray3 the most compatible AI video model for professional editorial workflows.
-
Draft Mode for 20x faster ideation
Ray3's Draft Mode enables rapid concept exploration at a fraction of the generation cost. It is purpose-built for the ideation phase — generate a dozen concept directions before selecting the one to render at full 4K quality.
-
Video modification from existing footage
Ray3 Modify allows precise, reference-controlled editing of existing clips — a capability that most video generation models don't offer. Feed it a clip and a description of what should change, and Ray3 applies the edit while keeping the rest of the scene intact.
-
Speed, quality, and cost tiers
Ray2 delivers ultra-realistic 60-second video at 1080p. Ray3 adds 4K HDR and visual reasoning. Ray3.14 is 4x faster and 3x cheaper than Ray3, with improved motion consistency. Together they give creators a full spectrum from rapid iteration to cinema-grade output.
How to use Luma's models on AI Compare Hub
- Choose your generation type. Luma's Ray series supports Text-to-Video and Image-to-Video workflows. Select the generation type that fits your project from the AI Compare Hub interface.
- Select a Luma model version. Choose Ray3 for the highest quality with 4K HDR and visual reasoning, Ray3.14 for faster results at lower cost, or Ray2 for long-form video up to 60 seconds. Add one or more other video models to compare outputs directly.
- Enter your prompt and generate. Write your prompt, set aspect ratio and resolution, then generate. Browse and compare the generated outputs from different model versions on AI Compare Hub.
Common questions
What AI models does Luma offer on AI Compare Hub?
Luma's model family on AI Compare Hub includes Ray2 and Ray3 for AI video generation, as well as Ray3.14 — a faster, more cost-efficient variant of Ray3 with native 1080p output. Ray2 supports text-to-video and image-to-video up to 60 seconds at 1080p. Ray3 and Ray3.14 bring enhanced quality, visual reasoning, and 4K HDR capabilities.
What is the difference between Ray2 and Ray3?
Ray2 (scaled to 10x the compute of its predecessor) generates up to 60-second video at 1080p with ultra-realistic motion and strong character consistency. Ray3 is more than twice the size of Ray2 and adds visual reasoning, 4K HDR output in ACES EXR format, and Draft Mode for rapid ideation — making it purpose-built for professional production pipelines rather than general creative use.
What is Ray3.14?
Ray3.14 is a refined variant of Ray3 that generates natively at 1080p, runs 4x faster, and costs 3x less per generation compared to Ray3. It delivers improved motion consistency and is optimised for higher-volume production workflows where speed and cost efficiency are priorities alongside output quality.
Which Luma model is best for AI video generation?
Ray3 is the highest-quality option — recommended for cinema-grade productions requiring 4K HDR, ACES EXR output, and the visual reasoning that produces the most coherent and physically accurate results. Ray3.14 is the better choice for most production workflows needing fast turnaround at lower cost. Ray2 is ideal when video length up to 60 seconds is the primary requirement.
Does Luma support video editing, not just generation?
Yes — Ray3 Modify allows creators to edit and reimagine existing video clips using precise keyframe and character reference controls. Describe the change you want to apply and Ray3 re-generates the specified portion while keeping the surrounding content intact.

About Luma
Luma develops the Ray video generation and Photon image generation model families. Luma's models are known for their natural motion quality, realistic lighting, and efficient generation speeds.
The video lineup includes Ray 2 at 720p and 540p resolutions for high-quality video generation, plus Ray Flash 2 variants for faster turnaround. The original Ray model remains available for earlier-generation workflows. For image generation, Photon and Photon Flash deliver photorealistic text-to-image output with fast generation times.
Luma models are available on AI Compare Hub via the Replicate API, supporting both text-to-video and image-to-video workflows.
