Which AI image model can I use commercially?
Direct Summary
The best commercial choice depends on the exact model licence and your revenue, not on image quality. FLUX.1 schnell is listed under Apache 2.0, while FLUX.1 dev and Ideogram 4 weights are non-commercial by default, and Midjourney and Stable Diffusion 3.5 set revenue thresholds around $1 million.
Technical Nuance & Operational Realities
Three separate questions are easy to blur: what the model weights licence allows, what a hosted service's terms allow, and who owns or may use the output. A permissive weights licence does not settle service terms, and a service plan does not settle third-party rights in the content.
The Apache License 2.0 grants "perpetual, worldwide, non-exclusive, no-charge, royalty-free" copyright rights (Section 2) and a patent licence (Section 3). The text does not use the phrase "commercial use", so we describe it as granting royalty-free rights to use, reproduce, distribute and sell. This article is informational and is not legal advice.
What the providers print
Licence comparison
| Model or service | Licence or terms as printed | Commercial position |
|---|---|---|
| FLUX.1 [schnell] | Apache 2.0 | Permissive |
| FLUX.1 [dev] and its tools (Fill, Canny, Depth, Kontext [dev], Krea [dev]) | FLUX.1 [dev] Non-Commercial License | Non-commercial; Black Forest Labs links a commercial licensing page |
| FLUX.2 [klein] 4B | Apache 2.0 | Permissive |
| FLUX.2 [dev], [klein] 9B | FLUX Non-Commercial License | Non-commercial |
| FLUX 3 Image Klein weights | FLUX Kommunity License | Terms not read; gated |
| Ideogram 4.0 weights | Ideogram Non-Commercial Model Agreement | Commercial use needs a paid licence ($300/month for 10K to 100K images per month; Enterprise above that) |
| Stable Diffusion 3.5 Large | Stability AI Community License | Free under $1M annual revenue with registration; above that Stability decides at its discretion |
| Midjourney | Subscribers own their images | Companies above $1M annual gross revenue need a Pro or Mega plan |
| OpenAI and Google hosted APIs | Provider service terms | Not reviewed here; read the current terms |
What to verify before deployment
- Whether the weights may be used commercially, and which file you downloaded.
- Whether hosting, modification or redistribution is allowed.
- Whether registration, attribution or revenue conditions apply.
- Whether the API agreement adds restrictions or data-retention terms.
- Whether generated content could infringe third-party rights.
- Whether privacy, publicity, trademark or industry rules apply.
Fewer restrictions are not automatically better
A model with fewer automated safeguards may give more flexibility for lawful creative work, and may also raise moderation, compliance and operational risk. Compare what each option lets you do lawfully against what your business can monitor.
At a Glance
Facts are as printed on provider pages read on 2026-10-21.
| Situation | Starting point | Watch for |
|---|---|---|
| Local inference with a permissive licence | FLUX.1 [schnell] or FLUX.2 [klein] 4B | Exact model file and version |
| Typography-led work at scale | Ideogram 4.0 via a paid licence or API | Self-Serve excludes full-precision weights, hosted API and resale |
| Company using Midjourney | Pro or Mega plan above $1M revenue | Plan terms change |
| Existing SD 3.5 pipeline | Community License | Registration and revenue threshold |
Verdict: FLUX.1 [schnell] is a useful candidate for businesses that want an openly licensed model, and hosted services may simplify deployment. Record the model, licence, provider and review date, and re-read the terms when anything changes.

Frequently asked questions
Which AI image model can I use commercially?
The best commercial choice depends on the exact model licence and your revenue, not on image quality. FLUX.1 schnell is listed under Apache 2.0, while FLUX.1 dev and Ideogram 4 weights are non-commercial by default, and Midjourney and Stable Diffusion 3.5 set revenue thresholds around $1 million.
Does open-weight mean unrestricted use?
No. Open weights can ship under licences that restrict commercial use, require registration or set revenue thresholds. Ideogram 4 weights, FLUX.1 dev and several FLUX.2 models are non-commercial by default, so the licence file for the exact model and version matters more than the label open.
Can I use AI-generated images commercially?
Often, but it depends on the model licence, the provider agreement, your plan and the content itself. Midjourney says subscribers own the images they create, with a Pro or Mega plan required for companies above $1 million annual revenue. Check privacy, trademark and publicity rules separately.
