Quick answer / recommendation
Use a locked Midjourney model + an exact prompt template + explicit parameter flags (--seed, --stylize, --chaos, --quality, --style raw, --iw) and turn OFF Remix. That combination gives you reproducible, brand-consistent outputs. Save the template in a shared prompt library and enforce it via /settings or a shared Discord bot channel.

Why this works
In Midjourney the variable factors that cause “wildly different” styles are: model version changes, stylize/chaos defaults, image-weighting (when using reference images), Remix, and occasional platform updates. The seed only guarantees repeatability if every other input (model version, parameters, prompt text, image prompt order/weights) is identical.

Decision criteria (which knobs to lock)
- Need tight consistency for production assets: lock model version (--v), seed (--seed), set low stylize (--stylize 0–50), set --chaos 0, use --style raw, and increase --iw for image refs. Use exact aspect ratio and quality flags.
- Need controlled variation for exploration: use higher --stylize or --chaos and omit a fixed seed.
- Budget considerations: higher --quality costs more; lock quality only when you need final renders.
- Team size/workflow: use a shared prompt template and store it in a common doc or channel to avoid drift.

Practical debugging checklist (run these in order)
1) Confirm model version: type /settings in Discord or add --v 5 (or the version you want) in every prompt. If the model changed recently, explicit --v is essential.
2) Turn OFF Remix: if Remix is enabled it adds randomness. Use /settings and toggle Remix off.
3) Lock the seed: add --seed 12345 to your prompt. Re-run the exact prompt + seed to verify identical output.
4) Lock stylization: add --stylize 0 or --stylize 50. Default stylize can change across versions.
5) Reduce randomness: add --chaos 0. This minimizes unexpected composition changes.
6) Use style raw: add --style raw to limit Midjourney’s artistic stylizing layers.
7) If using reference images: fix image order and use --iw (image weight) to control influence. Small changes in image order/weight alter results.
8) Fix aspect ratio and quality: add --aspect 4:5 (or your desired AR) and --quality 1 (or 2 for higher fidelity; note cost).
9) Confirm prompt text exactness: even extra spaces, punctuation, or different emoji can change outputs—use exact saved strings.
10) Test reproducibility: run the same full command in the same channel (same bot) twice. If it still differs, include the full generation string and timestamps when asking support.

Best-for / Avoid-if
- Best-for: producing repeatable brand assets, style guides, product images where exact look matters.
- Avoid-if: creative exploration or concepting — for that use higher --stylize and --chaos and omit the seed.

If you still see drift
- Midjourney sometimes updates models; use explicit --v and file the difference with MJ support if outputs deviate. Also check if different team members are using different workspace settings or bot instances.

Quick example prompt (copyable)
/imagine prompt: “Brand mascot, flat vector, clean lines, limited palette” --v 5 --style raw --seed 12345 --stylize 0 --chaos 0 --quality 1 --aspect 4:5

Tool to use
Use Midjourney and lock settings via /settings and explicit flags in the prompt to enforce reproducibility.

If you want, paste one exact prompt you used (with flags) and I’ll point out the single offending parameter.
