InvokeAI vs Sogni

InvokeAI is a free, open-source creative engine for AI image generation. It runs on Linux, macOS, and Windows, or through self-hosted and API setups. A layer-based canvas supports drawing, painting, sketching, and image editing, while a visual node editor builds repeatable workflows. Listed model support includes Flux, SDXL, and SD 1.5, with Model Manager handling checkpoints, LoRAs, Textual Inversions, and ControlNets. Tools include ControlNet guidance, batch generation, prompt wildcards, and high-resolution upscaling. InvokeAI supports text-to-image generation, reference images, API access, and PNG output. External integrations include Google Gemini, OpenAI, BytePlus Seedream, and Alibaba Cloud DashScope; those providers bill usage separately. Local operation keeps data, prompts, and creations under the user's control. The former hosted Invoke.ai platform has shut down.

Sogni is an AI image-generation service with text-to-image creation, reference-image support, image editing, and API access. It supports PNG, JPG, and WebP output, and commercial use is included with Sogni Unlimited. The Free plan offers unlimited on-device rendering on Mac and iOS, more than 150 open-source models locally, free monthly Spark for filtered Supernet jobs, basic Supernet cloud rendering, and limited API access. Premium Spark costs $1.99 a month and provides pay-as-you-go Spark credits, a priority queue, and access to supported premium and partner models, with no monthly commitment. Sogni Unlimited costs $20 a month and includes credit-free fair-use Supernet rendering for supported open-weight models, full SDK and API access, up to four concurrent image jobs, and a three-day free trial. Unlimited Pro costs $50 a month and allows up to 16 concurrent image jobs, with higher-priority queue placement and a larger media queue. Enterprise has custom pricing, dedicated Supernet capacity, custom rate limits and SLA, and team account management.
