OpenArt

OpenArt is an image generation model aggregation platform that provides access to Stable Diffusion, DALL-E 3, DALL-E 2, Flux and other third-party models in a single unified interface. The free plan offers 40 trial credits valid for 7 days to test the platform. Paid plans range from Essential ($7/month) to Infinite ($28/month) with monthly or annual billing. Annual subscriptions offer 50% off all tiers. Each generation consumes credits based on the chosen model and requested output resolution: a Stable Diffusion generation costs significantly less than a premium DALL-E 3 generation. OpenArt benefits from its aggregator positioning to let users quickly switch between models and compare results.

OpenArt exposes a documented public API enabling image generation integration into external applications, making it a viable option for developers. The interface is not available in French. The strength is centralized access to multiple top-tier models, enabling quick comparison and switching based on generation type. The weakness is that credit-based billing can become opaque: you need to calculate your monthly needs carefully before choosing a plan, otherwise overage charges can accumulate quickly if you use premium models like DALL-E 3 regularly.
