v1 Classic (three workflows): Text to Image with 5000-char prompts, 6 size presets (square through landscape 16:9), inference steps 2–250, guidance 0–20, acceleration none/regular/high, negative prompt, seed, safety checker, PNG/JPEG output. Image to Image transforms one reference image with denoising strength 0–1 plus full parameter set. Image Edit edits specific elements (prompt ≤2000 chars), 1–4 outputs, sync mode, steps 2–49.

Z-Image: Fast T2I with 5 aspect ratios (1:1, 4:3, 3:4, 16:9, 9:16), prompts ≤1000 chars, simplified workflow with no advanced parameters. Generation 3–15 seconds.

v2 (two workflows): Text to Image with 5 aspect ratios (1:1, 3:4, 4:3, 9:16, 16:9), prompts ≤800 chars, seed control. Image Edit with 8 aspect ratios including 21:9, prompts ≤800 chars plus one image URL.

v1 Classic: Write prompt → choose size and parameters → generate → iterate with adjusted seed or guidance. For I2I: upload image → set strength → generate. For edit: upload image → describe change → choose outputs → generate.

Z-Image: Write prompt → pick aspect ratio → generate in 3–15s.

v2: Write prompt (≤800 chars) → choose aspect ratio → generate. For v2 edit: upload image + prompt → set ratio → generate.

When to pick which: Use v1 Classic for full creative control and long prompts; Z-Image for rapid ideation with format compliance; v2 for streamlined generation with modern quality and more aspect ratio options.
