Treating GPT Image 2 and Grok Imagine Image 2.0 as the same “good image button” is how teams burn a starter credit pack on the wrong ceiling—either a 4K poster brief that Image 2.0 cannot open on this site, or a Quality Mode edit loop they never started because they stayed on the other model.
They are two named still models, not one family with a marketing rename. OpenAI shipped ChatGPT Images 2.0 / GPT Image 2 on April 21, 2026 as a production still and edit model with stronger text, layout, and multilingual type (OpenAI launch; GPT Image 2 model card). xAI shipped Imagine Image 2.0 on August 7, 2026 as the new Quality Mode on grok.com/imagine plus iOS and Android, with first-class region tools and templates (xAI Image 2.0).
This page is a matched-still decision guide. We ran the same three prompts on both models at this site’s default still settings, listed those settings, and we do not name an overall champion.
TLDR
Grok Imagine Image 2.0 is the stronger default on this site when you want Quality Mode stills, region-first edits, multi-reference (up to five inputs), templates, and the one-click path at /image (xAI Image 2.0). GPT Image 2 is the stronger fit when the brief needs readable in-image type across scripts, a 4K output tier on the catalog route, or a dedicated poster-text workspace on SupaImagine’s GPT Image 2 page (OpenAI launch; image generation guide). There is no universal winner.
Key Takeaways
- Two entities, two dates: GPT Image 2 / ChatGPT Images 2.0 is the April 21, 2026 OpenAI still model (OpenAI). Image 2.0 is the August 7, 2026 xAI Quality Mode generation (xAI).
- Do not mix slugs: this site’s default is
grok-imagine-image-2. An oldergrok-imagineslug is a different catalog row—not Image 2.0. - Official jobs: OpenAI stresses production stills, edits, layout, and multilingual text (model card; community launch note). xAI stresses instruction fidelity, designer-like type, Magic Wand / segmentation / background removal, multi-ref ≤5, and templates (xAI).
- On-site resolution: GPT Image 2 exposes 1K / 2K / 4K. Image 2.0 exposes 1K / 2K with low / medium quality—no 4K on this catalog route.
- Starter credits: this site gives 10 signup credits. Default GPT Image 2 (1K = 5) covers two default stills. Default Image 2.0 (1K medium = 6) covers the first default still, not two.
- No overall champion: the three matched stills below are one seed each, not a lab ranking.

Family / timeline (keep the lanes straight)
GPT Image 2 is the 2026 Images 2.0 generation inside ChatGPT and the API—not GPT-4o image (2025) and not a Grok family member (OpenAI; GPT Image 2 card).
Grok Imagine Image 2.0 is the consumer Quality Mode that follows the May 6, 2026 Quality Mode API story. xAI documents the API id grok-imagine-image-2.0 (Image 2.0; image docs). On this site, use grok-imagine-image-2. Do not treat older grok-imagine as the same model.
For how Image 2.0 itself works—templates, Magic Wand, Quality Mode—use the Image 2.0 complete guide. For prompt structure, use the Grok Imagine prompt guide. This article only answers which still model for which task.
How we ran the matched stills
| Knob | GPT Image 2 | Image 2.0 | | --- | --- | --- | | Prompt | identical string below | identical string below | | Aspect | 1:1 | 1:1 | | Resolution | 1K (site default) | 1K (site default) | | Quality | n/a on this route | medium (site default) | | Seeds / retries | one generation each | one generation each |
We did not cherry-pick winners, upscale after the fact, or import a third-party six-test ranking. Captions say what this seed shows. A second seed can move lettering or skin.
Prompt A — poster type (1:1)
Editorial poster, large exact text "NIGHT MARKET", smaller exact text "Open Till Midnight", bilingual smaller exact text "夜市", modern Swiss graphic design, amber and indigo geometric shapes on warm cream paper, strong hierarchy, sharp small text, clean margins, no fake logos, no watermark
Prompt A · GPT Image 2 · 1K · 1:1 · generated for this comparison, published on this site. Look at whether “NIGHT MARKET”, “Open Till Midnight”, and “夜市” stay spelled and hierarchical.
Prompt A · Grok Imagine Image 2.0 · 1K medium · 1:1 · generated for this comparison, published on this site. Same string. Score spelling, CJK, and margin discipline—not “which looks cooler.”
Prompt B — product packaging (1:1)
Photoreal product still of a matte glass serum bottle labeled with exact text "LUMEN", frosted glass, soft window light from the left, pale stone slab, one eucalyptus sprig, commercial beauty packaging photography, centered hero, clean negative space, no extra logos, no watermark
Prompt B · GPT Image 2 · 1K · 1:1 · generated for this comparison, published on this site. Check the “LUMEN” mark, glass, and whether extra labels appeared.
Prompt B · Grok Imagine Image 2.0 · 1K medium · 1:1 · generated for this comparison, published on this site. Same string. Check label lock vs extra chrome.
Prompt C — portrait (1:1)
Professional portrait of a man in his early 30s, navy knit sweater, natural window light, soft indoor background slightly out of focus, natural skin texture, sharp eyes, calm expression, shoulders-up framing, photoreal editorial, no watermark, no text
Prompt C · GPT Image 2 · 1K · 1:1 · generated for this comparison, published on this site. Look at skin texture, eye sharpness, and whether stray text appeared.
Prompt C · Grok Imagine Image 2.0 · 1K medium · 1:1 · generated for this comparison, published on this site. Same string. Look at identity hold and knit detail.
What this seed showed (not a trophy): Prompt A spelled NIGHT MARKET, Open Till Midnight, and 夜市 on both sides. GPT Image 2 added a night-market scene; Image 2.0 stayed more Swiss-geometric. Prompt B locked LUMEN on both bottles; glass and eucalyptus held, bottle geometry differed. Prompt C hit navy knit + window light on both sides; they are two different people, which is normal for one seed each. Re-run before you lock a campaign face.
Scenario winners
| If your bottleneck is… | Prefer | Why | | --- | --- | --- | | Poster / packaging type you must be able to read, including CJK or mixed scripts | GPT Image 2 | OpenAI’s launch and model card put multilingual / production text in the center (OpenAI; model card). Confirm with Prompt A on the dedicated page. | | A 4K still on this catalog | GPT Image 2 | Image 2.0’s on-site route is 1K / 2K only. | | Quality Mode + region edit (wand / segment / knock-out) on the same still | Image 2.0 | First-class on the Aug 7, 2026 post (precise editing). | | Up to five reference stills in one generation | Image 2.0 | Official multi-ref ceiling is 5 (xAI). | | Product / headshot / icon / game templates | Image 2.0 | Packaged workflows on the launch post (templates). | | Fastest browser default on this site | Image 2.0 | /image already selects it. |
Pro move: lock composition on Image 2.0, then only switch to GPT Image 2 when type-at-4K or a dedicated poster-text page is the actual bottleneck.
Credits on this site (honest, not a price war)
Signup freeCredits = 10 on this site. That is not enough to finish a two-model control set at default settings.
| Default still | Credits | What 10 credits cover | | --- | --- | --- | | GPT Image 2 · 1K | 5 | Two default stills | | Image 2.0 · 1K medium | 6 | The first default still (4 left) | | Image 2.0 · 1K low | 4 | Two low-quality stills—not the default |

What We Know vs. What We Don’t
| We know (sourced) | We don’t know / won’t claim |
| --- | --- |
| GPT Image 2 launch 2026-04-21: production stills, edits, layout, multilingual type (OpenAI; community note) | That every host exposes identical 4K / thinking-mode chrome |
| Image 2.0 GA 2026-08-07 as Quality Mode on web + iOS + Android; Magic Wand / segment / BG remove / multi-ref ≤5 / smart resize / templates (xAI) | That every third-party UI clones grok.com chrome |
| Quality Mode API story starts 2026-05-06 (xAI) | That May API Quality Mode and Aug consumer 2.0 are byte-identical |
| This site: Image 2.0 default 1K medium = 6; GPT Image 2 default 1K = 5; Image 2.0 has no 4K | A starter pack that finishes both defaults twice |
| xAI’s Aug 7, 2026 post cites an Arena snapshot with Image 2.0 second and gpt-image-2 listed first (performance) | A live Arena rank, or that Elo picks your poster |
| Three matched stills above, one seed each | A six-test “overall winner” from another blog |
How to evaluate on this site (same prompts)
- Open Image 2.0 on /image (already the default).
- Paste Prompt A, then B, then C. Leave 1K / medium unless you are testing a single knob.
- Score: exact words, extra junk type, product lock, skin, and whether a region edit would save the frame.
- If the brief is 4K or poster type, run the same strings on SupaImagine GPT Image 2.
- Keep only the second-pass still. Do not invent a new brief mid-test.

FAQ
Is GPT Image 2 better than Grok Imagine Image 2.0?
Not universally. Pick by bottleneck: 4K / multilingual poster type → GPT Image 2; Quality Mode, region edit, multi-ref, or this site’s default → Image 2.0 (OpenAI; xAI).
Is “Grok Imagine” the same as Image 2.0?
No. Imagine Image 2.0 is the August 2026 Quality Mode model (xAI). On this site that is grok-imagine-image-2. Older grok-imagine is another row.
Does Image 2.0 do 4K here?
No. This catalog route is 1K / 2K with low / medium quality. Use GPT Image 2 when you need the 4K tier.
Can I run both models from this site?
Image 2.0 is the /image default. For a dedicated GPT Image 2 money page (readable poster text), use SupaImagine’s GPT Image 2 generator.
Do 10 free credits finish a fair A/B?
They finish two default GPT Image 2 stills or one default Image 2.0 still—not a full two-model, three-prompt grid. Plan the first credit on Image 2.0 here.
Should I trust Arena #2 as the decision?
No. xAI cited a dated Arena snapshot on August 7, 2026 (performance). Boards move. Run Prompt A–C on your brief.
Did you copy a third-party six-image ranking?
No. The stills above are our same-prompt seeds at listed settings. We do not import another site’s scoreboard.
Where should I start if I only have one prompt today?
Start on this site’s Image 2.0 generator. Switch to GPT Image 2 only if type-at-4K is the actual fail.
Can I edit after the first still?
Yes on Image 2.0’s official stack: Magic Wand, segmentation, background removal (xAI). GPT Image 2 is also an edit model on OpenAI’s surfaces (guide). Prefer region edit over a full regen when composition is already good.
Grok Imagine Image 2 vs GPT Image 2 — does word order change the answer?
No. Same two models. We cover the reversed query here so you do not need a second article.
