StableDiffusion users seek H3 API quality via local workflows

A user on Reddit is seeking advice on achieving image generation quality comparable to the H3 API's 2k renders using StableDiffusion. They have conducted tests with their RTX 4090 and ComfyCloud, finding the API quality good but not significantly superior to local workflows. The user is asking for community consensus on whether the H3 API is essential or if similar results can be obtained through local methods like seedvr2, multi-step workflows, or latent upscales. AI

IMPACT Users are exploring methods to replicate high-quality AI image generation locally, potentially reducing reliance on paid APIs.
