MidJourney was probably the most correct one, producing the signal, the futuristic ambiance of town and the wall. Ideogram generated the wall and metropolis however omitted the signal. Regardless of these points, SD3’s capacity to include all key components of the composition, even with imperfect textual content, made it the winner on this state of affairs.
Winner: MidJourney—however this was a fortunate era, as Ideogram tends to be extra constant at producing textual content in photos general.
Conclusion
SD3 demonstrates important enhancements over its predecessor SDXL and aggressive efficiency towards MidJourney and Ideogram in a wide range of situations. SD3 excels in immediate adherence, as promised, in addition to element and inventive type copy. SD3 has confirmed its potential as a sturdy base mannequin.
Nevertheless, its heavy censorship and perplexing limitations in producing folks in sure positions recommend it might be greatest used together with different instruments.
For instance, customers could wish to generate their photos with SD 1.5, SDXL, or Pixart, after which encode these generations and ship them to a de-noise sampler with SD3. This may offload the picture creation course of to SD3 however would use a earlier era as a reference as a substitute of producing the whole lot from scratch. This makes much more sense presently, as there are not any customized fashions and even Controlnets or LoRAs to present customers extra choices to affect the mannequin.
In its present state, SD3 is best than SDXL for lots of use instances—however not sufficient to interchange it.
