Hutengeneza picha kutoka kwa `prompt` ya maandishi kwa bajeti ndogo ya hatua: `num_inference_steps` hukubali 4 hadi 8, chaguomsingi 4. Chagua mipangilio ya `image_size` kutoka square hadi portrait_16_9 na landscape_16_9 (chaguomsingi landscape_4_3), na uombe picha 1 hadi 4 katika png, jpeg au webp. `seed` inaweza kuwekwa ili matokeo yarudiwe. Hili ni toleo la utengenezaji pekee, bila picha za ingizo.
