Current Free/Open Shortlist
Free access is not the same as model cost. Some models are open or local, while others offer hosted free-tier access that can change. The scores below come from the same Sonnet 4.6 public benchmark used by the image leaderboard.
| # | Model | Sonnet Score | Cost/Image | Tier |
|---|---|---|---|---|
| 1 | Qwen Image 2512 | 3.87 | Free/open path | Free |
| 2 | Reve Image | 3.76 | Free-tier path | Free |
| 3 | Flux Dev | 3.50 | Open-weight | Free |
| 4 | Ideogram 2a | 3.66 | Free-tier path | Free |
| 5 | Flux Schnell | 3.35 | Open/local path | Free |
How to Choose
Best free/open quality
Qwen Image 2512
It has the strongest current Sonnet score among the free/open-access shortlist at 3.872.
Best hosted free-tier candidate
Reve Image
It has a lower Sonnet score than Qwen, but it is easier to try if you want a hosted free-tier path instead of a local model.
Best lightweight local option
Flux Schnell
It is the lowest-scoring model in this shortlist, but it remains useful when speed, local control, and zero marginal cost matter most.
Free vs. Budget
The best free/open option is not always the best cheap option. GPT Image 2 Low is stronger than every model on this page, but it is a paid model at $0.014/image. If you can pay a small amount per image, use the budget guide before committing to a free-only workflow.
If you need zero marginal cost or local control, start with Qwen Image 2512 for quality and Flux Schnell for speed. If you want hosted access without setting up local inference, try the free-tier candidates and verify their current limits.
