Editor's note: This is a documentation-led edition. We have not yet run our own hands-on tests of these tools, so nothing here judges image quality or names a winner. Every price, licence term and feature comes from the vendors' own pages, accessed on 16 October 2026. A tested update will follow.

Most "best image generator" lists compare pictures. For creators who sell work, the bigger differences sit in the terms: who owns the output, whether the vendor offers legal cover, whether the file carries an AI label, and whether the model runs offline.

This shortlist is organised by job, with each tool's price, editing controls and documented limits. For the mechanics first, start with how AI image generators work.

How we chose: the selection criteria

No scores here. A tool made the list when its official documentation showed all six:

  1. A defined creator job: style exploration, editing in conversation, design inside existing apps, text-heavy graphics or local generation.
  2. Published pricing or a free tier on an official page.
  3. Written output terms: who owns or may use generated images.
  4. Documented editing controls, such as region edits or reference images.
  5. A stated position on marking, or its absence in what we read.
  6. Stated limits: usage caps, licence conditions or known weaknesses.

Inclusion means a tool passed these checks, not that we have confirmed its output quality.

Job 1: style exploration and art direction

Midjourney

What it is for: exploring looks quickly, using style references, moodboards and personalisation. Its documentation says the default model, V8.2 (default since 24 July 2026), focuses on "aesthetics, image quality, and Personalization".[1]

Editing controls: V8.2 introduced an Edit model that changes images from written instructions, builds new images from up to four reference images, and powers inpainting and outpainting in the Editor. It replaces Omni Reference, Character Reference and Retexture.[1][2]

Price (as of 16 Oct 2026): Basic $10 a month, Standard $30, Pro $60, Mega $120, or 20% less billed annually. Plans include 3.3 to 60 hours of fast GPU time; Standard and above add unlimited Relax-mode generation.[3]

Terms: Midjourney's terms say "You own all Assets You create with the Services to the fullest extent possible under applicable law". Companies with more than $1 million in annual gross revenue must buy Pro or Mega. Outputs come with no non-infringement warranty and no indemnity, and you are "solely responsible for determining the appropriateness of using or redistributing the Assets".[4]

Documented limits: images are public and remixable by default; Stealth mode is Pro and Mega only, and "best efforts". Midjourney gets a licence to your inputs and outputs. Region edits on HD images return SD.[3][4][1] The Midjourney pages we read do not describe Content Credentials or watermarking.

Job 2: generating and editing inside a chat assistant

ChatGPT Images (OpenAI)

What it is for: making and revising images in conversation, including text and transparent backgrounds. The current model is ChatGPT Images 2.5.[5]

Editing controls: select part of an image and describe the change, or describe the edit without a selection. Templates and, on mobile, sketches are also supported. OpenAI warns: "Highlights are not always precise, and edits may extend beyond the area you selected."[5]

Price (as of 16 Oct 2026): ChatGPT Images is available on all tiers. "Images with thinking" is on Plus, Pro and Business.[5] Plus costs $20 a month.[6] Free-tier image limits are not published as a number.

Terms: OpenAI's consumer terms say you "(a) retain your ownership rights in Input and (b) own the Output", while warning that output may not be unique.[7] The consumer terms carry no indemnity. OpenAI does indemnify API and ChatGPT Enterprise, Edu and Healthcare customers against third-party IP claims over output. That cover excludes trademark claims over use in trade, modified outputs, and cases where the customer knew or should have known an output infringed.[8]

Marking: images from ChatGPT, Codex and the API carry Content Credentials and a SynthID watermark, though OpenAI says "Coverage may vary by product, model, export path, file type, and when the content was created."[9]

Gemini with Nano Banana (Google)

What it is for: quick generation and conversational edits, including combining several photos and keeping a character consistent across images.[10]

Naming, verified 16 Oct 2026: "Nano Banana" is Google's name for Gemini's built-in image models. The Gemini app uses Nano Banana 2 by default. Google's image page says Google AI plans unlock Nano Banana 2.1, and paid subscribers can also "Redo with Pro" using Nano Banana Pro.[10][11]

Editing controls: local edits, multi-image references and edits to uploaded photos. Editing is limited to users 18 and over. Downloads are 2K with a Google AI plan and 1K without one.[10]

Price (as of 16 Oct 2026, US): Free $0; Google AI Plus $4.99 a month; AI Pro $19.99; AI Ultra from $99.99. Usage limits rise with each tier.[12] If you hit your daily Nano Banana 2 quota, you cannot redo further images with Pro.[10]

Terms: Google's terms say "Google won’t claim ownership over that content."[13] Google's generative AI indemnity covers Google Cloud and Workspace services, including generally available Imagen and Gemini models on its developer platform. The consumer Gemini app is not on that list.[14]

Marking: Google says Gemini adds an invisible SynthID watermark and a visible watermark to show images are AI-generated.[11]

Job 3: design work inside Creative Cloud

Adobe Firefly

What it is for: generating and editing within Adobe's apps (Firefly web, Photoshop, Illustrator, Express and others), with Generative Fill and Expand, Text to Vector, and partner models from Google, OpenAI, Black Forest Labs and others in one place.[15][16][17]

Price (as of 16 Oct 2026): Adobe's US product page lists Firefly Standard at US$9.99 a month with 2,000 credits, plus a free plan with daily generations.[15] Adobe's credits FAQ gives 2,000, 4,000, 10,000 and 50,000 monthly credits for Standard, Pro, Pro Plus and Premium. Every tier includes unlimited "standard" generations; premium features use credits.[18] Prices for the higher tiers did not render on Adobe's official pages when we checked, so we do not quote them.

Terms and indemnity: Adobe offers IP indemnity for outputs of its own Firefly models, but only to customers whose agreement links to its Firefly product description. It covers listed features, such as Text to Image and Generative Fill, exported from eligible apps under a qualifying plan. It excludes non-Adobe models and beta features, and Adobe notes outputs "may not be unique".[16] Partner models are "not developed by Adobe", and you decide whether one suits your project.[17] Separately, Firefly Creative Production for Enterprise covers some copyright claims over generally available Google and OpenAI models. That cover excludes trademark, publicity and privacy claims.[19]

Marking: Adobe attaches C2PA metadata (Content Credentials) when qualifying generative tools create or modify content, and says it "cannot be disabled for qualifying content". It adds no visible label by default.[20]

Job 4: text-heavy graphics

Ideogram

What it is for: posters, social graphics and logos where lettering matters. Its documentation has dedicated guides for text in images, logo making, editable text layers, masks and inpainting, and transparent backgrounds.[21]

Price (as of 16 Oct 2026): Free (30 credits a week if you sign in with Google, Apple or Microsoft); Plus $20 a month or $15 billed yearly, with 2,400 credits; Pro $60 or $42 yearly, with 7,500; Team $30 per user.[21]

Terms: "We do not claim any ownership rights in your User Input or User Output". Ideogram allows commercial use but adds: "We expressly disclaim any liability arising from your use of any User Output for a commercial purpose."[22] There is no indemnity in the terms.

Documented limits: "On the free plan, everything you generate is public." Paid plans keep new images private until you publish them.[21] The terms forbid removing watermarks; the pages we read do not describe C2PA metadata. The terms were last revised in August 2024.[22]

Job 5: running models on your own hardware

Local models trade convenience for control: no per-image fees once set up, and prompts stay on your machine. The licence matters more than any plan page. For the trade-off in depth, see Midjourney vs. Stable Diffusion for creator control.

Stable Diffusion 3.5 (Stability AI)

What it is for: an 8-billion-parameter text-to-image model (3.5 Large) that you can run through ComfyUI or Diffusers, quantise for smaller graphics cards, and fine-tune.[23]

Licence (as of 16 Oct 2026): the Community Licence is "Free for research, non-commercial, and commercial use for organizations or individuals with less than $1M in total annual revenue." Above that, you need an Enterprise licence at custom pricing.[24][23]

Documented limits: Stability says the model "was not trained to be factual or true representations of people or events", and recommends developers add their own safety measures.[23] Running it yourself means no automatic marking unless you add it.

FLUX open weights (Black Forest Labs)

What it is for: generating and editing from text, with single and multi-reference editing in one model (FLUX.2 [dev], 32 billion parameters). The model card links quantised setups for high-end consumer cards such as the RTX 4090.[25]

Licence (as of 16 Oct 2026): this depends on the model. FLUX.2 [klein] 4B is Apache 2.0, free for commercial use. FLUX.2 [klein] 9B, FLUX.2 [dev] and FLUX.1 [dev] weights are non-commercial, and self-hosting them commercially needs a paid licence.[26] The FLUX.2 [dev] model card adds that "Generated outputs can be used for personal, scientific, and commercial purposes, as described in the FLUX [dev] Non-Commercial License."[25] Read that licence before you rely on it. BFL says "The simplest way to use FLUX commercially is through our API".[26]

Marking: BFL says its hosted FLUX.2 Pro API applies signed C2PA metadata, and its [dev] inference code includes an example pixel watermark.[25]

Documented limits and risks

Ownership is a contract term, not a legal guarantee. Vendors can assign you whatever rights they hold, but whether an AI image is protected by copyright depends on the law where you are. In the US, prompts alone have not been treated as authorship. Our AI training and copyright explainer covers where that stands.

Outputs may not be unique. OpenAI, Ideogram and Adobe all say so.[7][22][16]

Indemnity is narrow. Where it exists, it is tied to business agreements, specific features and generally available models, and usually excludes trademark claims and modified outputs.[8][14][16][19]

Marks can be lost.

"they do not guarantee that content is accurate, unedited, legally owned, or presented in the correct context."

That is OpenAI on its own provenance signals. It adds that Content Credentials can be lost through screenshots or file conversion.[9] A missing credential proves nothing either way; our content credentials explainer explains why.

Public by default on Midjourney's lower plans and Ideogram's free plan.[3][21]

Who it suits, and who should skip it

  • Midjourney suits illustrators and art directors exploring looks. Skip it if you need private work on a budget plan or vendor legal cover.
  • ChatGPT Images suits creators already in ChatGPT who want quick iterative edits. Teams needing indemnity need API or Enterprise-type plans.
  • Gemini suits casual and social creators who want a free start. Skip it if a visible watermark is a problem.
  • Adobe Firefly suits Creative Cloud designers and brand teams that need indemnity and provenance. Skip it if you want metadata-free files.
  • Ideogram suits makers of posters, merchandise and social graphics with lettering. Skip it if you need contractual legal cover.
  • Stable Diffusion 3.5 and FLUX suit technical creators with a capable GPU who want privacy and fine-tuning. Skip them if you won't manage hardware and licences.

How to test it yourself

Seven checks on your own brief
  1. Write one brief you actually need, such as a poster with a headline, a product shot and a character in two scenes.
  2. Run the same brief on two shortlisted tools at the same aspect ratio, and save the prompts.
  3. Make one region edit and one text change on each. Check whether anything outside the selection changed.
  4. Download the original file and check it in a C2PA inspector (for OpenAI images, OpenAI's own checker at openai.com/verify) to see what provenance survived.[9]
  5. Re-save it as a screenshot or compressed JPEG and check again. Do not swap in an AI detector here: our comparison of AI detectors vs. content credentials explains why a detector's score is a different kind of evidence.
  6. Read the output and indemnity clauses for the exact plan you would buy, not the marketing page.
  7. Note the real cost per usable image, including retries and credits.

A worked example (hypothetical)

This scenario is invented to show how the checks apply. It is not a test result.

A two-person studio designs gig posters and sells prints. It needs clean lettering, a consistent mascot and commercial rights. Revenue is under $1 million.

Ideogram's documented text tools fit the lettering, and its terms allow commercial use, but it offers no indemnity and the free plan publishes everything, so the studio would start on Plus at $20 a month.[21][22] For the mascot, Midjourney's Edit model accepts up to four references. At this revenue Standard is allowed, but images stay public without Pro.[3][4][2] If a record-label client later asks for legal cover, the studio would look at Adobe Firefly under a qualifying agreement.[16] It would keep final files' Content Credentials intact.

Terms first, then a test on its own brief.

Questions readers commonly ask

Which AI image generator is best overall?

We have not tested output, so we do not name one. Choose by job and terms, then run the checks above.

Do I own the images I generate?

Midjourney, OpenAI, Google and Ideogram say they do not keep ownership or assign it to you. Copyright protection itself depends on national law and human authorship. See our copyright explainer.

Do I need to label AI images?

Platforms and laws differ. Under the EU AI Act, providers' machine-readable marking duties apply from 2 August 2026, with until 2 December 2026 for systems already on the market. Whether you need a visible label depends on where and how you publish. The content credentials explainer covers what marking does and does not prove.

How do I keep a character consistent across images?

Use reference-image features: Midjourney's Edit model, Gemini's multi-image references or FLUX multi-reference editing.[2][10][25] The workflow in how to keep characters consistent in AI video applies to stills too.

Can these tools make video?

This list covers stills. See best AI video generators, or our Runway review for one video tool's documented image-to-video and editing features.
