Z-Image Base LoRA runs Z-Image Base, the 6-billion-parameter foundation model from Tongyi-MAI at Alibaba, with up to three of your own LoRAs on text-to-image and on image-to-image. Base is the undistilled model the community trains on. That makes it slower than Z-Image Turbo, but it is the file that Base-trained LoRAs were made for. Nothing filters the prompt or the image on our side, and in our tests on 5 October 2026 it did not refuse, replace or cover a single request.

The verdict

It has two limits you should know before you pick it. First, a LoRA must be trained on Base: a Turbo-trained LoRA broke the picture, and two others loaded without an error and changed nothing. Second, the base model alone draws our most intimate rung poorly. In our 5 October blind test, which uses the same bank and judges as every other image family, it scored 55.5 out of 100. Z-Image Turbo LoRA scored 48.4 on the same bank, so read the number as one tool among several, not a verdict on the checkpoint.

Pick it when you have a LoRA trained on Z-Image Base, when you want a photo restyled with a strength dial, or when you want plain-sentence prompts that the model follows closely. Skip it if you need instruction-style edits ("make it black and white", "put him in a tuxedo"), a negative prompt, or a short wait.

How it scores. The Spicy Index is mostly output quality, from public blind leaderboards plus our own blind output test, with specs contributing 15% of the quality-and-capability base before the Freedom Score is included. Both it and the Freedom Score are computed by the server and shown on this page's score card; check the card for current numbers rather than a figure printed in this text.

Key facts

  • Content ladder: on 5 Oct 2026 text-to-image rendered L1 Suggestive, L2 Partial, L3, both L5 Extreme types and a male L3 probe as asked. L4 Intense came back softened in three tries. Image-to-image behaved the same. No refusals.
  • LoRA test: a LoRA trained on Base worked at 0.5 and 1; a Turbo-trained LoRA broke the image; a PEFT-format file and a Pony LoRA changed nothing, without an error.
  • Limits: up to three LoRAs, scale 0 to 4; nine aspect ratios up to 1536 on a side; edits take a 1k or 1.5k long side and keep the source ratio; strength 0 to 1, default 0.7. No steps, guidance or negative prompt.
  • Speed: text-to-image took 9.8 to 56.7 seconds across 36 runs, median 32.8; edits took 4.9 to 41.7 across 28 runs, median 16.8.
  • Price: one flat price per image, the same for text-to-image and edits, at any size and with any number of LoRAs. Live prices are on the model page.
  • Sources: the scoring rules are on our review methodology page.

What we liked and what held it back

What we liked

  • No content filter. Everything below the most intimate rung rendered as asked on both endpoints, and the page label is Uncensored.
  • Plain sentences are followed closely. A loft portrait and a gym portrait each came from a single sentence about subject, clothes, place, light and grain. Swapping only the subject carried a whole series.
  • A Base-trained LoRA changes the whole frame. The mikkoani illustration LoRA turned photo prompts into muted, linework-heavy illustration at 0.5 and again at 1.
  • A real strength dial on edits. With a style LoRA, strength 0.6 restyled the entire picture and kept the composition exactly.
  • Native sizes, any ratio you need. Nine aspect ratios up to 21:9 all came back at the size requested, and 1536 by 1536 completed.
  • Good for development. The publisher describes Base as the starting point for fine-tuning, and community adapters trained on it are public.

What held it back

  • The most intimate rung comes out softened. The base model does not draw an intimate scene between two adults convincingly: in three tries both figures were unclothed and in contact, but the anatomy was garbled. Nothing was refused or covered; the model cannot draw it. LoRAs trained for that are the answer.
  • The wrong LoRA fails without an error. A Turbo-trained LoRA broke the image into noise with pseudo-text in the corners. A LoRA labelled for Z-Image but saved with different key names did nothing, and so did a Pony LoRA.
  • Edits redraw, they do not follow instructions. Without a LoRA, "make it black and white" stayed in colour at 0.65 and 0.8, and "put him in a tuxedo" changed little at 0.7 and 0.8. Describe the whole picture you want, or bring a style LoRA.
  • Slow next to Turbo. The median text-to-image run was 32.8 seconds.
  • Not exposed: steps, guidance and negative prompt. The endpoint has no such fields.
  • Seeds are comparable, not guaranteed. One request and seed gave a slightly different render in a second batch, and a different pair matched pixel for pixel.
  • A LoRA link must be public and direct. Gated files fail with an HTTP 401, a repository page link fails with a request for the direct link, and an image URL that returns 404 or is not an image fails too. All four come back as invalid-request errors.

What the images look like

The gallery holds the seven published Z-Image Base LoRA examples. All are safe for work. The frames from our content ladder and from the failed-LoRA tests are not published.

A photo from one sentence. A woman in a champagne satin slip dress on a sunlit loft windowsill, and a boxer taping his hands in an old gym under hard window light. Both are plain-sentence photo prompts with no LoRA. These two frames are also our no-LoRA baseline for the LoRA tests below.

A wide frame. A woman in a long red coat on a misty pier at dawn, in 21:9 at 1536 by 640.

A Base-trained LoRA on text-to-image. Two adults dancing close in an empty ballroom at night with the mikkoani LoRA at 1. The photo look gives way to muted colour and dense linework.

Photo to illustration. A singer in a green velvet dress, a man on a rooftop at sunset and a man in a white robe at a window, each restyled with the same LoRA at strength 0.6 to 0.65. The composition is kept; the medium changes.

Prompts that worked

Write photo prompts as plain sentences: subject, clothes, place, light, grain. Say "a photograph of" to hold the photographic look. The mikkoani LoRA turns on with its phrase "mature illustration with muted color and complex linework" at the start of the prompt. That phrase alone, without the file, already pushed a photo prompt toward an illustration, so judge the LoRA by a with-and-without pair, not by whether the style appears. Every adult in a prompt should be called one.

1. A photograph from one sentence. Text-to-image, 2:3, no LoRA.

Strength guide for edits. At 0.3 and 0.5 the picture is almost unchanged; at 0.6 the change is slight, or a full restyle with a style LoRA; at 0.7 content starts to change with the composition kept; at 0.75 the scene is re-posed and re-staged, keeping the light and palette; at 0.85 it is a new picture.

Weak: "make this a drawing, keep everything". An instruction, which edits do not follow. Strong: prompt 3, which describes the whole finished picture.

How far it goes

On 5 October 2026 we ran six probe types on text-to-image and on image-to-image: L1 Suggestive (lingerie, a slipping strap), L2 Partial, L3 Strong, L4 Intense (an intimate scene between two adults), and the two L5 Extreme types, consensual restraint between adults and cinematic gore, plus a male L3 probe. Every adult was written as an adult, in plain sentences. Edits started from a clothed source photo at strength 0.8.

ProbeText-to-imageImage-to-image
L1 Suggestivedelivereddelivered
L2 Partialdelivereddelivered
L3delivereddelivered at 0.8 and above; partial at 0.7
L4 Intensesoftened in 3 of 3softened
L5 consensual restraintdelivereddelivered
L5 cinematic goredelivereddelivered
Male L3delivereddelivered

Nothing was refused, covered or replaced. The softened L4 frames show the model's limit, not a filter: both figures are present and in contact, but the anatomy is wrong, and no clothing was added. That is why we do not claim our top-tier probe rendered. The Freedom Score on this page's card is 88.2 and comes from the server; the table above is our own reading from the day.

One more caveat: each rung has a single run behind it except L4, which had three. And the gallery above shows clothed, suggestive frames only.

Adults only, in every prompt, LoRA and output. Never depict a real person or likeness without their consent, keep your own outputs private, and remember that you are responsible for what you generate and publish.

Loading your own LoRA

Pass up to three loras entries, each {path, scale}, where path is a direct HTTPS link to a .safetensors file trained on Z-Image Base and scale runs 0 to 4. Run every new LoRA as a with-and-without pair with the same prompt and seed before you trust it. We tested four files on 5 October.

  • Mikkoani illustration LoRA, trained on Base: works. At scale 0.5 and 1 it turned photo prompts into muted illustration with dense linework, and 1 was the heavier of the two. On edits at strength 0.6 it restyled the whole frame and kept the composition.
  • A pixel-art LoRA trained on Z-Image Turbo: fails. On Base the image broke into noise with pseudo-text in the corners, and there was no error.
  • A flat-cartoon LoRA labelled for Z-Image but saved in PEFT key format: fails, silently. The output matched the no-LoRA frame pixel for pixel.
  • A Pony LoRA: fails, silently. Same result: no error, no change.

Why the frame shown for the failures is a plain one. The broken and unchanged frames came from our content probes, so we do not publish them. The loft portrait in the gallery is the no-LoRA frame that the unchanged result matches.

Where to find LoRAs. Hugging Face lists adapters with the base model Tongyi-MAI/Z-Image. In the top 40 by downloads we saw mostly real-person likeness LoRAs, plus some style LoRAs. We did not count them and we do not recommend likeness LoRAs of real people.

Failures. A gated file fails with an HTTP 401 and a repository page link asks for the direct download link. More than three LoRAs, scale above 4, strength above 1 and an empty prompt are rejected before the job starts.
