Imagine Heart 1.5 is 4 credits at 4K

imagine-heart-1-5 is a text-to-image row at 4 credits and 4K — the same credit figure as Imagen 4, a different provider page, not a video family.

Four credits and a 4K ceiling show up twice on the stills shelf. That is a meter coincidence, not a twin. ImagineArt 1.5 is the Imagine-provider row whose catalog slug is imagine-heart-1-5: stylised, mood-led image generation that leans expressive rather than literal. Imagen 4 is Google’s photoreal, text-only stills row. Same listed credit figure. Same 4K chip. Different vendor, different look, no duration on either. Neither one is a clip.

Four credits and 4K are the catalog facts

Quote the Imagine Heart row and stop inventing a second product:

• 4 credits per generate
• 4K max output
• text-to-image only
• no duration list
• audio is null
• provider Imagine
• catalog slug imagine-heart-1-5
• display name ImagineArt 1.5

The catalog description is blunt: stylised, mood-led image generation that leans expressive rather than literal. Emotive social visuals, album-art energy, illustrative looks. That is the job. There is no 5s slider because there is no time. Prompting “the song swells” will not produce a stem. Prompting “slow orbit of the cover” will not produce a clip. You type. You get a still.

The door is text-to-image. Pick this row when the still should feel like a cover: a campaign key, a story thumbnail, a poster that has to hit from a lock screen. If the brief is a literal SKU on a white sweep, you are on the wrong stills row. Imagine Heart 1.5 will give you album-art energy whether you asked for it or not; that is the description. Mixing the jobs — “photoreal bottle, album-art energy” — is how you get a bottle from a dream and a label legal cannot read.

Four credits is the named cost of one still, not a sketch pad you reroll until a video model “feels it.” Approve the illustration. Then decide whether anything else should happen to the file.

Imagen 4 is the same meter, a different provider page

Imagen 4 is also 4 credits, also 4K, also text-to-image, also no duration, also audio null. The catalog line is Google’s premium photoreal still, described as text-only. Provider is Google, not Imagine. Photoreal is the listed strength. requires_image is false: you describe the shot.

That is the whole overlap. Same credit figure. Same resolution chip. Different provider page. Different look. Scanning the catalog by “4 credits, 4K” and picking whichever row is on screen is how a photoreal pack shot becomes an illustrated cover, or how a mood key becomes a literal bottle nobody asked for.

Use Imagen 4 when the brief is a photoreal hero — product plate, key art, a face the brand already signed — and the input is a prompt, not a reference upload. Use Imagine Heart 1.5 when the brief is expressive stills. Do not name-swap them because the meter matches. The meter is not the model.

Each row will do what its description says, at the same listed 4 credits. Pick the description. The credit figure does not pick for you. 4K on an image row is a stills ceiling. 4K on Veo is a video tier. Do not read them as one family.

This is not a video family

Content type is image. Category is text-to-image. There is no image-to-video sibling hiding under the Heart name, and there is no native-audio flag to flip. People open a video UI because it is already on screen, spend a motion row, and call the first frame “the Imagine look.” A first frame is not an approved still. It is a side effect.

When the still is signed and the next job is motion, change rows. Image-to-video is the launcher for that later job. The motion prompt should describe only motion: camera, grain, a slow push. Do not re-describe the illustration. The still already is the illustration. Do not generate the cover inside the video model and hope the 4K chip on Heart meant the clip would match.

There is no 4s / 6s / 8s list on this slug because those numbers belong to video rows. Asking Imagine Heart 1.5 for an eight-second take is a category error, not a missing setting. Asking it for a soundtrack is the same error. Audio is null because there is nothing to mix.

If you needed type that reads as type on a dense layout, that is a lettering stills row, not this mood row. If you needed a cheap iterate on an approved photograph, that is an edit-image row. If you needed cinematic frames with time, that is a video row after the still exists. Imagine Heart 1.5 is the mood-led 4K still at 4 credits. Do not stretch the slug.

Photo editor is a later instruction, not this row

The AI photo editor is instruction-based editing: you hand it a photograph and a sentence — remove an object, swap a colour, leave what you did not mention — and it hands back the same file with that one thing different. It is not text-to-image. It is not Imagine Heart 1.5.

Do not open the photo editor expecting a 4-credit 4K Heart generate. Do not open Heart expecting it to “keep this photo, make it moody.” Heart’s input is a prompt. The editor’s input is a file plus an instruction. Running Heart because the editor was the last tab is how an approved photograph becomes a cousin illustration. Running the editor on a Heart still after you like the still is a different, later job: one change, same plate.

Imagen 4 does not take a reference still and lock identity. Heart 1.5 does not either. If you already have a plate and you need a change, you are on an edit-image path. If you need a new mood key from a sentence, you are on Heart. If you need photoreal from a sentence, you are on Imagen 4. If you need seconds, you are not on any of those three. Generate the still. Pick it. Stop. Change the row when the job changes.

FAQ

Is Imagine Heart 1.5 the same as Imagen 4 because both are 4 credits at 4K?

No. Same listed credit figure and the same 4K ceiling. Imagine Heart 1.5 is the Imagine-provider mood-led still at slug imagine-heart-1-5. Imagen 4 is Google’s photoreal, text-only stills row. Pick by description, not by the meter.

Can Imagine Heart 1.5 generate video?

No. Content type is image. Four credits buys a 4K-capable still. There is no duration list and no native audio. Motion is a different model after you approve the art.

What is the slug imagine-heart-1-5?

That is the catalog slug. The display name is ImagineArt 1.5. Link the model page at /models/imagine-heart-1-5. Do not look for a separate “Heart video” row under the same name.

Should I use the AI photo editor to get the Imagine Heart look on an existing photo?

No. The photo editor is an instruction edit on a file you already have. Heart 1.5 is text-to-image from a prompt. If you need a mood still from a sentence, run Heart. If you need one change on a signed photograph, run the editor. Do not treat the 4-credit 4K chip as a bridge between those jobs.
