AI Image Generation 2026 — Flux, Imagen 4, Midjourney v7, Ideogram, Recraft, Firefly, DALL-E, Stable Diffusion: An Honest Comparison

한국어English日本語

Prologue — Two Earthquakes

August 2022. Stable Diffusion 1.4 was released. Before that, image generation AI lived inside the closed betas of OpenAI's DALL-E 2 and Midjourney v3. The moment SD shipped with open weights, the whole category was reshaped. Anyone with a 4090 could generate unlimited images locally. ComfyUI, Automatic1111, Fooocus, and Forge exploded. LoRA, ControlNet, and IP-Adapter extensions arrived in waves. 2023 was "the year of the SD ecosystem."

Early 2024. A name appeared called Black Forest Labs. It was the original SD core team — Robin Rombach, Andreas Blattmann, Patrick Esser, Dominik Lorenz — who had left Stability AI to start a new company. In August they announced Flux.1, a three-tier system: open-weight Schnell (Apache 2.0), non-commercial Dev, and API-only Pro. On day one Flux beat SD-XL, and within a year it became the new default for open-weight image models. That was the first earthquake.

Spring 2025. The second earthquake hit. Midjourney v7 launched in April and reset the bar for consumer aesthetic again. In June Google's Imagen 4 went GA. Adobe Firefly Image 4 followed the next quarter. In August, Black Forest Labs released Flux.1 Kontext, opening a separate track called "image editing." In November, OpenAI replaced DALL-E 3 with gpt-image-1 as the default model inside ChatGPT. Ideogram pushed its typography lead further with v3.

As of May 2026, the landscape looks like this.

This post tries to map that landscape honestly. Which model wins which slice, what local vs cloud actually means in 2026, whether ComfyUI is really dead (it is not), and where the lawsuits land. The same shape as the music post — five axes, one decision tree, an anti-pattern table at the end.

One-line take: in 2026 image generation there is no "single best model." The five axes — typography, consistency, editing, licensing, aesthetic — have split into different tools. Knowing the tool turns an hour-long job into a ten-minute one.


1 · The Arrival of the Flux Era — A New Baseline for Open Weights

1.1 Who Is Black Forest Labs

March 2024. The core researchers at Stability AI — Robin Rombach, Andreas Blattmann, Patrick Esser, Dominik Lorenz — left to start Black Forest Labs. Headquartered in Freiburg, Germany. Seed round in August 2024, around 31 million USD, led by Andreessen Horowitz with General Catalyst, Y Combinator, and MätchVC joining.

These are the original authors of SD 1.x, 2.x, and SD-XL. The people who built the open-weight image generation category started a new company, and their first product was Flux.1.

1.2 The Three Tiers of Flux.1

Flux.1 shipped as three variants of the same architecture trained on the same data.

The structure is clever. Open the weights to build the ecosystem; recover commercial value through Pro and licensing. In 2025, Flux.1.1 Pro and Flux.1.1 Pro Ultra (up to 4 megapixels) extended the Pro lane.

1.3 Why It Beat SD-XL

Three technical points explain the jump.

  1. 12 billion parameters. Roughly 4.6x SD-XL (2.6B) and 50 percent larger than SD 3.5 Large (8B).
  2. Rectified Flow. A variant of diffusion. Standard diffusion learns a curved path from noise to image; Rectified Flow tries to learn a straight one. Fewer sampling steps produce higher quality.
  3. MMDiT architecture. The multimodal diffusion transformer introduced in Stable Diffusion 3. Text and image flow through the same transformer blocks together. Prompt adherence jumped sharply over SD-XL.

In human-evaluation benchmarks at launch (August 2024), Flux Pro beat Midjourney v6, DALL-E 3, and SD 3 across the board. Hands, in-image text, and anatomy — the classic weak spots — improved the most.

1.4 Flux Kontext — The Editing Answer

May 2025. Black Forest Labs released Flux.1 Kontext. It is an "image + text -> edited image" model. Different from text-to-image.

What makes Kontext different.

Before Kontext, image editing was a stack of ControlNet, IP-Adapter, inpainting masks, and LoRA. Now a single text instruction does most of it.

1.5 Flux Tools — Auxiliary Models

November 2024. Black Forest Labs released Flux Tools.

These absorbed most of the ControlNet and IP-Adapter ecosystem from the SD 1.5 and XL era.

1.6 The Local Execution Reality

Running Flux Dev on a 4090.

ComfyUI, Forge, SwarmUI, and InvokeAI all support Flux natively. By 2025 "local image generation = Flux" became the default.


2 · The Consumer Aesthetic Peak — Midjourney and Imagen

2.1 Midjourney v7

Midjourney is the aesthetic reference for the category. Other models chase the look Midjourney sets. v7 went to alpha in April 2025 and GA in June.

Key changes in v7.

In a single line — Midjourney wins on "the aesthetic finish of a single scene." For a poster, an illustration, a single moodboard frame, the output is the least-corrected by a working designer.

Weaknesses.

2.2 Google Imagen 4

Imagen 4 went GA in June 2025. Two big steps up from Imagen 3 (December 2024).

What stands out.

Weaknesses.

2.3 OpenAI gpt-image-1

In April 2025 OpenAI introduced a new default image model called gpt-image-1 inside ChatGPT. The earlier default, DALL-E 3, moved to backup.

Where gpt-image-1 sits.

Because it is the model most invoked inside ChatGPT, by raw call volume it may be the category leader in 2026. The accurate framing is "not the highest quality, but the lowest-friction interface."

3 · Typography and Designer Tools — Ideogram, Recraft, Firefly

3.1 Ideogram v3 — When Text Has to Appear

Ideogram is a Toronto startup founded in August 2023. CEO is Mohammad Norouzi, formerly at Google Brain and one of the original Imagen authors. From day one the company picked "text inside images" as its core differentiator.

Core features.

Typography accuracy is not "the letters are readable" but "the designer can ship the output as-is." That gap is decisive against Midjourney, Flux, and Imagen.

Weaknesses: realism slightly behind Imagen 4 Ultra, and character consistency slightly behind Midjourney's --cref.

3.2 Recraft — AI for Designers

Recraft picked a single position — "AI for graphic designers." Recraft V3 launched in October 2024 and briefly topped the Hugging Face TTI leaderboard.

Differentiators.

After V3, V3 Plus shipped in 2025 with further realism gains. V3.5 is in beta as of May 2026. For a designer, Recraft is the single tool that handles "generate -> edit -> deliver in another format."

Pricing: 50 free credits per day, Basic 12 USD per month, Pro 33 USD per month.

3.3 Adobe Firefly — The Licensing Clarity Story

Adobe Firefly's value prop is one sentence: "trained only on Adobe Stock and public domain." Other models live in a licensing grey zone; Firefly does not.

Firefly Image 4 launched in May 2025 and Image 4 Ultra arrived that autumn.

Strengths inside the Adobe ecosystem.

Weaknesses.

4 · Open Source and Local — Stable Diffusion 3.5, SD-XL, HiDream, Janus-Pro

4.1 Where Stable Diffusion Stands

Stability AI, who created the category in 2022, had a rough 2024-2025.

In May 2026, SD 3.5 is "still used but not the category leader." Flux is clearly ahead. Stability AI, after a 2024 CEO turnover and financial struggles, has shifted weight toward Stable Audio, Stable Video, and 3D.

4.2 SD-XL — The Power of the Legacy

SD-XL persists for one reason. The LoRA, ControlNet, IP-Adapter, and Textual Inversion ecosystem is enormous. Tens of thousands of SD-XL LoRAs live on Civitai. For specific art styles, characters, and aesthetics, SD-XL still offers the deepest catalog.

When to stay on SD-XL.

When to move to Flux.

4.3 HiDream — The 2025 Newcomer

HiDream-I1, released April 2025, is a 17B open-weight model under the MIT license. In some academic benchmarks it edges out Flux Dev.

ComfyUI supports it natively. As of May 2026, HiDream is the "real free alternative to Flux Dev."

4.4 Janus-Pro / Krea — Adjacent Directions

Janus-Pro (DeepSeek, January 2025). A multimodal LLM that also generates images. Text and images flow through the same model. 7B parameters, MIT license. Quality is below Flux, but the paradigm of "LLM as image generator" is worth tracking.

Krea AI. Not a model vendor but a workflow platform. Aggregates multiple models behind one interface. Its real-time canvas (the AI fills in as you sketch) is the differentiator. Krea launched its own model Krea-1 in 2025.

5 · Tools vs Models — Where ComfyUI, Forge, and A1111 Are

5.1 Are the UIs Dead? No.

A common myth in 2025 was that Automatic1111, ComfyUI, Forge, Fooocus, and InvokeAI faded as the category moved to hosted models. Wrong. The category shape just changed.

ComfyUI got bigger in 2025-2026. Node-based, so new models get new nodes quickly. Flux, HiDream, and every video model (Wan, HunyuanVideo, LTX-Video) lands in ComfyUI first. It is now the de-facto standard for AI image and video workflow automation.

Forge UI (Forge / Forge Classic). A fork of Automatic1111. Memory optimization runs Flux on 8 GB GPUs. The UI is friendlier than ComfyUI, so it became the entry point for beginners.

Automatic1111 (A1111). Update cadence slowed in 2025. Flux support arrived later than Forge, and ControlNet lagged. The legacy SD-XL user base stays, but new entrants moved to Forge/ComfyUI.

InvokeAI. Pivoted to commercial SaaS. Targets enterprise workflow solutions.

SwarmUI. Uses ComfyUI as a backend but presents a friendlier UI. Recommended for users who don't want to draw node graphs.

Fooocus. Midjourney-style simple UI. Best onboarding for non-technical users.

5.2 A Sample ComfyUI Graph

Flux Dev plus Flux Kontext plus LoRA plus upscale, in a single graph.

[LoadCheckpoint Flux Dev]
        |
        +-[Text Encoder] <- [Prompt: "cyberpunk alley, neon"]
        |       |
        |  [KSampler] <- [Empty Latent 1024x1024]
        |       |
        |  [VAE Decode]
        |       |
        +-[LoadKontext] <- [Reference image]
        |       |
        |  [Kontext Edit] <- [Instruction: "make it sunset"]

        +-[Upscale 4x ESRGAN]
        |       |
        +-[Save Image]

Build the graph once and you can rerun it with different prompts to generate hundreds of variants. The automation matches direct API use, with the bonus of seeing every intermediate step visually.

6 · Lawsuits and Licensing — Honestly

6.1 Stability AI vs Getty Images

The most-cited case. Getty Images sued Stability AI in both the UK and US (2023).

UK ruling, November 2025, High Court of Justice.

The US case is still pending in May 2026. US law differs and the outcome may differ.

6.2 Other Active Cases

6.3 What Users Should Do

Safer commercial options (May 2026).

  1. Adobe Firefly. Adobe Stock plus public domain only. Indemnification. The safest.
  2. Google Imagen 4. Indemnification. License-clean training data marketed explicitly.
  3. OpenAI gpt-image-1. Standard OpenAI terms. Indemnification only on the Enterprise plan.
  4. Flux Schnell, self-hosted. Apache 2.0 weights. Outputs belong to the user.
  5. HiDream-I1. MIT weights. Commercial use OK.

Grey zone.

Risky behavior.

6.4 However the Lawsuits End

Three scenarios.

Scenario A — "training is transformative fair use" prevails. AI training is legalized. Output-level trademark and similarity issues remain separate. The "explicit licensing" marketing edge of Firefly and Imagen narrows.

Scenario B — "training requires licensing" prevails. Stable Diffusion and Midjourney face licensing settlements or forced retraining. Costs jump, subscriptions rise, and Firefly and Imagen pull further ahead.

Scenario C — Settlement and licensing standardize. Like the Disney-AI rumored deals: major-IP licensing becomes the norm, academic and open-source models live in a separate track. The most likely outcome.

Epilogue — Checklist, Anti-Patterns, Next Post

The shock of SD 1.4 in 2022, Flux 1's overtake in 2024, the Midjourney v7 / Imagen 4 consumer jump in 2025, and the Flux Kontext / gpt-image-1 editing paradigm shift in 2026 — the category has never sat still. Music and video shifted the same way. The difference is that images stabilized first. Users now ask "which tool for which job" rather than "which model is best." There is no one-line answer, but the five axes are clear — aesthetic (Midjourney), realism (Imagen), typography (Ideogram), designer workflow (Recraft / Firefly), open weights (Flux / HiDream).

Tool Selection Checklist

  1. Does the image contain text? If yes, lead with Ideogram or Recraft.
  2. Commercial use? If yes, Firefly / Imagen indemnification or self-hosted Flux Schnell.
  3. Single shot or a series? If a series, character consistency (--cref, Flux Kontext) is mandatory.
  4. Editing required? Pick one of Flux Kontext, gpt-image-1, or Photoshop Generative Fill.
  5. Local feasible? 16 GB+ GPU runs Flux Dev. 24 GB runs HiDream.
  6. Automation required? Use APIs. Midjourney is unsuitable for automation.
  7. Vector required? Recraft is nearly alone here.
  8. Realism or illustration? Realism -> Imagen 4 Ultra. Illustration -> Midjourney v7.
  9. Multi-turn editing? gpt-image-1 (chat) or Flux Kontext.
  10. License safety top priority? Firefly first, Imagen second.

Next Post

The next post is "AI Video Generation 2026 — Sora 2, Veo 3, Runway Gen-4, Kling 2, Pika 2, Open-Sora: Where Are We Really?". Same shape — category explosion (the 2024 Sora demos) and maturation (2026's commercial tools), the hardest slice (long consistency, character identity, fingers and physics), open-source options (Open-Sora, Mochi, HunyuanVideo, Wan), real workflows (ads, short-form, concept visuals), and the licensing fight (NYT-OpenAI, Disney licensing). With that post the image / music / video triangle closes.
