Luma Ray3 and Ray3.2: What Luma Actually Documents
Ray3 was the first video model to generate true 16-bit HDR — that still stands. It does not do 4K, and it is no longer Luma's current model.
Two things get repeated about Ray3 that Luma's own documentation contradicts: that it reaches 4K, and that it is the latest release. This page quotes Luma's machine-readable model page line by line, dates every check, and marks what is still unverified. Last verified August 7, 2026.
Luma Ray is not in our generator — and some of our own pages used to say otherwise
You cannot generate with any Luma model on ImagineToVideo. Until August 7, 2026 two of our own landing pages listed "Luma Ray" among the models we offer, and one of them said so inside an answer about what a subscription includes. That was wrong, and it was corrected in the same change that published this page. We would rather say that plainly than correct other people's pages while carrying an error on our own.

Open the generatorWhat Luma's documentation states
Ray3.2 is the current model
Luma's own words: "Ray3.2 is Luma's current video generation model." Ray3 and Ray3.14 came before it; Ray2 and Dream Machine are marked deprecated.
Maximum resolution is 1080p
Luma's model page lists 1080p as the maximum. No 4K tier is documented — which settles the single most repeated claim about this model.
Native 16-bit HDR
Ray3 was the first video model to generate true high-fidelity 16-bit HDR, and HDR generation remains documented in the current model. This first has not been overturned.
EXR export at ACES2065-1
Output can be exported as EXR in the ACES2065-1 colour space for grading and VFX, which is what makes this line unusual for professional pipelines rather than social clips.
Confirmed, with the source for each line
Every statement below comes from Luma's own machine-readable model page or its launch press release. Nothing here is sourced from a third-party spec summary.
Ray3.2, released June 2026, is Luma's current video generation model.
Luma's wording is "Ray3.2 is Luma's current video generation model, built for production pipelines." Ray3 and Ray3.14 precede it.
The documented maximum resolution is 1080p.
This is the figure that matters most on this page: it is the reason the widely repeated "up to 4K HDR" claim does not hold.
HDR generation is native and in 16-bit colour.
Not a post-process tone map — the model generates in high bit depth, which is what allows the EXR pipeline below to be useful.
Output exports to EXR at ACES2065-1 for grading and VFX.
ACES2065-1 is the interchange colour space used by film and advertising pipelines, which is what distinguishes this line from models aimed at social video.
Modify Video V2 runs up to 20 seconds at 1080p.
Modify Video is Luma's video-editing surface rather than a generation mode; the 20-second figure applies to it specifically.
Ray2 and Dream Machine are marked deprecated.
Worth knowing before following any tutorial written before mid-2026 — a large amount of published Luma guidance targets surfaces Luma no longer recommends.
Ray3 launched on September 18, 2025 as the first video model to generate high-fidelity 16-bit HDR.
This is a vendor claim from Luma's launch announcement, but unlike most "first" and "best" claims on these pages we have found nothing that overturns it. It is still standing.
Which Luma version is which
The version numbering is genuinely confusing — 3.14 reads like it comes after 3.2 but does not. Here is what Luma's own page says about each.
| Version | Official status | What Luma says |
|---|---|---|
Ray3.2 | Current model, released June 2026 | |
Ray3.14 | Superseded by Ray3.2 | |
Ray3 | Superseded; historically significant | |
Ray2 | Deprecated | |
Dream Machine | Deprecated |
Ladder as documented on 2026-08-07. If you arrived searching for "Ray3", the model you would actually use today is Ray3.2.
Claims in circulation, checked one by one
These are the Ray3 specs being repeated across the web. For each one, what Luma's own documentation says.
| Claim in circulation | What Luma's documentation says | Verdict |
|---|---|---|
Up to 4K HDR output | Contradicted by Luma's own documentation HDR and resolution are separate axes. 16-bit HDR at 1080p is exactly what is documented — the HDR half of the claim is right, the 4K half is not. | |
Ray3 is Luma's latest model | Contradicted — superseded by Ray3.2 | |
Ray3.14 was released on January 26, 2026 | ⚠️ Unconfirmed — date not on any official page we found | |
More than 25 million registered users | ⚠️ Unconfirmed — no official figure on the pages we checked | |
First video model to generate 16-bit HDR | Confirmed and still standing Not every vendor claim on these pages fails. This one holds. |
Every verdict reflects the state of the sources on 2026-08-07 and is re-checked weekly.
Where Luma sits on the public leaderboard today
Ray3 drew a lot of coverage at launch. Here is what the blind-test arena shows now.
| Claim | Who said it, and when | As of 2026-08-07 |
|---|---|---|
First to generate high-fidelity 16-bit HDR | Still standing — we found nothing that overturns it | |
Position on Artificial Analysis text-to-video | Various third-party rankings quoted since launch | No Luma model appears on the leaderboard we checked. The leader is Gemini Omni Flash at Elo 1244. Absence from an arena can reflect its coverage decisions, not model quality. It is not evidence that Ray3.2 got worse. |
Elo is a relative score: everyone's number moves when new models enter. Check the live leaderboard rather than any figure quoted in an article — including this one.
What this means for you
If you are grading footage in a professional pipeline
This is the case where Luma is genuinely differentiated and we are not: native 16-bit HDR with EXR export at ACES2065-1 drops straight into a colour pipeline. Nothing on this site does that. If that is your requirement, Luma is where to go — just plan around 1080p rather than 4K.
If you saw "4K HDR" and that was the appeal
The HDR half is real; the 4K half is not in Luma's documentation. If resolution is what you actually need, VEO 3.1 on this site documents 720p, 1080p and 4K. If bit depth is what you need, resolution is not the axis to optimise and Luma is the better fit.
How to check any Luma claim yourself
Four steps, no account required. Luma publishes a page specifically for this.
Open Luma's model information page
Go to lumalabs.ai/llm-info. Luma maintains it as a machine-readable summary of its own models, which makes it the cleanest primary source of any vendor on these pages.
Search the page for "current"
That sentence names the model you would actually be using. Today it says Ray3.2 — which is how you catch every article still presenting Ray3 as the newest release.
Search for "resolution"
The maximum is stated outright. This is the one step that settles the 4K question, and it takes about five seconds.
Trace every other number to Luma
Release dates, user counts and benchmark positions should trace back to lumalabs.ai or a Luma announcement. For several of the figures in circulation, that trail stops at somebody else's blog.
Update log
Both sources are re-checked weekly. Every change lands here with its date.
Page published; 4K claim refuted and our own pages corrected
Luma's model page was found to list 1080p as the maximum resolution, which contradicts the widely repeated "up to 4K HDR" claim, and to name Ray3.2 rather than Ray3 as the current model. Two of our own landing pages incorrectly listed Luma Ray as an available model; both were corrected in the same change.
Ray3 launches as the first 16-bit HDR video model
Luma announced Ray3 with native high-fidelity 16-bit HDR and EXR export in ACES2065-1. That specific first has not been overturned since.
Questions people are asking about Luma Ray3
Does Luma Ray3 support 4K?
No. Luma's own model information page lists the maximum resolution as 1080p, and no 4K tier appears on it. The confusion comes from conflating HDR with resolution: Ray3 generates native 16-bit HDR, but it does so at up to 1080p. If you need 4K, VEO 3.1 documents it and runs on this site.
What is Luma's latest video model?
Ray3.2, released June 2026. Luma's page states plainly that "Ray3.2 is Luma's current video generation model." Ray3 and Ray3.14 came before it, and Ray2 and Dream Machine are marked deprecated — worth knowing before following any older tutorial.
What does 16-bit HDR actually get me?
Bit depth, not sharpness. Generating in 16-bit high dynamic range preserves far more tonal information than a standard 8-bit output, which is what makes the footage hold up under aggressive colour grading rather than banding. Combined with EXR export at ACES2065-1, it drops into a professional finishing pipeline instead of needing to be treated as a finished clip.
How long can Modify Video output be?
Luma documents Modify Video V2 at up to 20 seconds at 1080p. Modify Video is Luma's editing surface rather than a generation mode, so that figure applies to it specifically.
Can I still use Dream Machine?
Luma marks Dream Machine and Ray2 as deprecated on its model page. A large amount of Luma guidance still online was written for Dream Machine, so check the publication date before following any walkthrough.
Was Ray3 really the first 16-bit HDR video model?
That is Luma's claim from its September 18, 2025 launch announcement, and we have found nothing that overturns it. Unlike most "first" and "best" claims we check on these pages, this one is still standing.
Can I use Luma Ray on ImagineToVideo?
No. No Luma model is in our generator. Two of our own landing pages listed "Luma Ray" as available until August 7, 2026 — that was an error and it has been corrected. Luma is available directly from Luma, including a full API.
Ray3 is 1080p HDR. If you need 4K, we have it.
VEO 3.1 documents 720p, 1080p and 4K, and it runs on this site alongside Seedance 2.5, Kling V3 and Seedance 2.0 — with their real parameter limits listed.
