Pick Midjourney for stylized beauty, ChatGPT Images (OpenAI's DALL·E successor) for effortless everyday images, Stable Diffusion for free private control on your own hardware, and Flux for photorealism and sharp text. This guide compares the four families as they stand in 2026 — price, ease, quality, control, licensing — so you choose by job, not hype.
| Generator | What it is | Price path | Signature strength |
|---|---|---|---|
| Midjourney | Subscription image service (web and Discord); model on version 8.x as of mid-2026 | From about $10/month; no free tier | Polished, stylized aesthetics and strong prompt adherence |
| DALL·E (now ChatGPT Images) | OpenAI's image generation, folded into ChatGPT and powered by its GPT Image (gpt-image) models | Free tier with limits; paid ChatGPT plans from about $20/month | Conversational editing and the easiest workflow — just chat |
| Stable Diffusion 3.5 | Open-weights family from Stability AI (Large, Large Turbo, Medium) | Free download; needs your own GPU | Full control, fine-tuning and total privacy |
| Flux (FLUX.1) | Open-weights and API models from Black Forest Labs | Free weights (schnell) or API/paid hosted services | Photorealism and unusually accurate text rendering |
Model versions move fast, so treat them as a snapshot. Prices are approximate as of September 2026; check vendor pages before paying (links in references below).
Midjourney built its name on images that look finished — rich color, strong composition, a polish that needs little prompt engineering. The browser-first workflow generates four variations per prompt, with built-in inpainting and outpainting. There is no free tier, plans start around $10 a month, and images stay in a public gallery unless you pay for stealth mode. For portfolio-grade concept art and marketing visuals, it is the shortest path to "wow."
The DALL·E name now mostly refers to history: OpenAI retired the standalone DALL·E experience inside ChatGPT on August 30, 2026, and image generation happens through ChatGPT Images, running on the newer GPT Image (gpt-image) family. The workflow is the killer feature — describe, refine and edit in plain conversation, upload a photo and ask for changes — and it works on the free tier, with paid plans adding higher limits and a slower "thinking" mode.
Stability AI's open-weights family runs entirely on your own hardware via tools like ComfyUI: unlimited generations at electricity cost, nothing uploaded to a stranger's server, and full freedom to fine-tune or add ControlNets for precise composition. The trade-off is setup — a capable GPU (smaller variants work on roughly 8 GB of VRAM) and patience with node graphs.
Black Forest Labs' FLUX.1 models made their name on two things most generators fumble: believable skin and light, and text that renders legibly inside the image — posters, signs, product labels. The family spans open weights (FLUX.1 schnell, Apache-2.0) and source-available versions (FLUX.1 dev, non-commercial without a paid license), plus hosted API access. It runs locally on strong GPUs or hosted through services like Replicate and fal.ai.
| Factor | Midjourney | ChatGPT Images | Stable Diffusion 3.5 | Flux |
|---|---|---|---|---|
| Ease of use | Easy (web) | Easiest (chat) | Hard (setup) | Medium-hard local; easy hosted |
| Free option | None | Yes, limited | Yes (weights) | Yes (schnell weights) |
| Runs offline | No | No | Yes | Yes |
| Photorealism | Excellent | Good | Good | Excellent |
| Text in images | Good (improved since v7) | Good | Fair | Excellent |
| Editing / inpainting | Built-in | Conversational | Add-ons | Add-ons and Kontext tools |
| Commercial use | Paid plans grant rights | Covered by OpenAI terms | Community License | Schnell free; dev needs license |
Image quality is subjective and prompt-dependent, but the reliable differences are structural — price, privacy, control, licensing.
Selling AI images is normal business in 2026, but the fine print differs. Midjourney's paid plans grant commercial usage rights, and stealth mode keeps work private. ChatGPT Images output is covered by OpenAI's terms. Stable Diffusion 3.5 ships under the Stability AI Community License — free for individuals and small companies below the stated revenue thresholds, with an enterprise license above. Flux splits: schnell is Apache-2.0, while dev is non-commercial unless you buy a license from Black Forest Labs.
| Your job | Best pick | Why |
|---|---|---|
| Concept art and polished marketing visuals | Midjourney | Best out-of-the-box aesthetics; pay the subscription |
| Quick images and edits inside an existing workflow | ChatGPT Images | Conversation-based; free tier is real; no new tool to learn |
| Private or unlimited generation on a budget | Stable Diffusion 3.5 | Free weights, runs offline, fully yours — if you have a GPU |
| Photoreal product shots, posters with text | Flux | Best realism and typography; use schnell free or dev with license |
| Trying everything for $0 today | ChatGPT free tier + local open weights | Chat for convenience, local models for volume and privacy |
The pattern behind the table: services win on convenience, open weights win on control. Most teams keep one of each — a subscription generator for polished client work and a local model for everything else.

ChatGPT's image feature has a usable free tier, and Stable Diffusion and Flux (schnell) are free to download and run on your own GPU. Midjourney has no free tier — every plan is paid.
Flux and the current Midjourney releases are generally the strongest for photorealism in 2026. Output changes between versions, so test the same prompt in two or three generators before committing.
Yes, with a decent GPU. Stable Diffusion 3.5 and Flux have open weights that run locally through tools like ComfyUI — smaller variants need about 8 GB of VRAM. Midjourney and ChatGPT images are cloud-only. Local generation costs electricity, not subscriptions, and keeps images private.
OpenAI retired the standalone DALL·E experience inside ChatGPT in August 2026 and now delivers images through ChatGPT Images, powered by its GPT Image (gpt-image) family. The product you pay for today is ChatGPT with images; check OpenAI's help pages for current limits.
All four can be used commercially, but read each license. Midjourney's paid plans grant usage rights (larger companies need higher tiers); Flux schnell is Apache-2.0 while dev needs a paid license; Stable Diffusion 3.5 is free commercially below Stability's stated revenue thresholds; OpenAI's terms cover images made in ChatGPT.
