I kept seeing designers ask if Seedream 4.5 could finally fix the classic problem: the image looks perfect, but the text is wrong. So I spent a week running structured tests. This Seedream 4.5 tutorial is the exact workflow I now use to get AI images with accurate text, fast. If you're hunting for the best AI image generator for text and realistic AI images for marketing, this walkthrough keeps things practical, reproducible, and honest.

Getting Started with the Seedream 4.5 Tutorial

Setup, interface overview, and first-time configuration

Here's how I get Seedream 4.5 production-ready in under 10 minutes.

  • Account and workspace: I create a clean project per client/campaign. Keeping assets separated saves me from version chaos later.
  • Interface tour: Three panels matter for speed, Prompt (left), Viewer (center), and Controls (right). Controls is where Seed, Guidance/CFG, Sampler, and Resolution live. I pin these to "Quick" so I'm not digging through menus mid-iteration.
  • First-time configuration (my defaults):
  • Canvas: 1024×1365 for posters or 1080×1080 for square social. Bigger than 1024 on the long side can reduce letter warping.
  • Sampler: Balanced/Default (switch to "Sharp" only when type edges look soft).
  • Guidance (CFG): 6.5–7.5. Lower than 6 gives more creative drift: higher than 8 starts to overfit and can distort letters.
  • Steps: 28–40. I start at 30: going above 40 hasn't improved text for me.
  • Seed: Lock it. I always enable a fixed seed for A/B tests: it's the only way to fairly compare prompt tweaks.
  • Upscaler: 2× Standard for most cases: switch to "Text-Focused" if you see ringing around strokes.

Why this matters: text accuracy is fragile. Stable settings reduce randomness so your prompt changes actually reflect in the output. That's how I move fast without messy surprises.

Text-to-Image Basics in Seedream 4.5

How to generate images from text prompts step by step

My baseline flow for AI images with accurate text:

1. Write the scene first, then the exact text in quotes.

  • Prompt example: "A sunlit cafe storefront, shallow depth of field, natural wood, modern signage", "SUNNY BEANS" as the main shop sign, clean sans-serif, black letters, centered.

  • Quoting the target text gives the model a stronger anchor. I also specify type style and placement.

2. Add anti-drift constraints.

  • I add: "legible signage, accurate spelling, no extra letters, no mirrored text, no handwriting." This stops the model from getting cute.

3. Set parameters.

  • Resolution 1024×1365, CFG 7, Steps 32, Seed locked.

4. Generate 4–8 variations quickly.

  • I change only one thing per batch (font vibe, lighting, or camera angle). This keeps the experiment clean and teachable.

5. Evaluate like a production designer.

  • Can I read the text at 50% zoom? Are letterforms consistent (S curves, E arms, spacing)? If it fails, I don't upscale. I fix the prompt or composition first.

6. Fix minor issues with a surgical re-roll.

  • I nudge by adding: "bold uppercase, evenly spaced kerning, straight baseline." If spacing is still off, I shift to a deck-mounted sign instead of a curved awning, flat surfaces simply succeed more often.

In my tests, this approach produced usable results in 2–3 batches. Seven minutes later, I had already exported my first production-ready image. For AI tools for designers, that speed is the difference between a concept and a deliverable.

Image Editing Features in the Seedream 4.5 Tutorial

Seedream 4.5's editor is where I rescue near-misses without restarting.

  • Inpainting for text fixes: I mask only the sign area, then prompt: "SUNNY BEANS", bold, uppercase, evenly spaced, flat sign, no extra letters. Keep CFG at 6–7 during inpaint so it respects the existing scene.
  • Outpainting for layout: Need more headroom for a headline? I outpaint upward 15–25% and prompt for "clean wall texture" so the added area doesn't invent new signage.
  • Type-safe upscaling: I use 2× Standard first. If edges halo, I re-run with "Text-Focused" and a sharpening of 5–10%. Over-sharpening creates crunchy edges: I stop once the stems stay clean at 100%.
  • Color and contrast: A tiny contrast lift (5–8%) helps readability in paid ads. It's a small move with big ROI.

Reality check: If the base geometry is warped (e.g., bent baselines on a curved surface), inpainting won't fully fix it. I switch the composition to a flat plate or banner, then re-run. That's how I keep outputs realistic and commercially usable.

Multi-Reference Mode Explained in Seedream 4.5

Using multiple references for more accurate image generation

This is my favorite Seedream 4.5 feature for branded work. Multi-Reference lets me guide the model with 2–4 assets:

  • Ref A: Product photo (locks materials and proportions).
  • Ref B: Logo or wordmark PNG/SVG (locks letter shapes).
  • Ref C: Style image (lighting/mood), optional.

My settings that consistently work:

  • Image influence: Product 0.6–0.7, Logo 0.8–0.9, Style 0.3–0.5. I keep the logo highest to improve spelling and stroke fidelity.
  • Text prompt still includes the exact word in quotes. Example: "LUMINO" on the label, uppercase, centered.
  • Seed locked: CFG 6.5.

Workflow:

1. Add the three refs.

2. Generate low-res previews.

3. Inspect the logo area at 100%.

4. If the logo looks "almost right" but off by a serif, I raise Logo influence by 0.05 and re-roll.

Compared with a plain prompt, Multi-Reference reduced typos for me by ~40% across five product mockups. If you're producing realistic AI images for marketing, this mode is the difference between a passable concept and something a client can actually approve.

Pro Tips for Advanced Use of the Seedream 4.5 Tutorial

Here's what moved the needle most in my tests:

  • Use exact quotes for target text and avoid mixing multiple phrases in one prompt. One sign, one message.
  • Prefer flat surfaces and perpendicular camera angles when text must be perfect. Curves and steep angles invite letter distortion.
  • Keep CFG between 6–7.5. Above 8, I see more double letters.
  • Lock the seed for A/B tests: change seeds only after you've dialed the prompt.
  • If the model invents extra words, add: "no additional signage, no watermark, no decorative script."
  • Batch strategy: 4 variations × 2 prompt tweaks beats 1 giant batch of 16. You learn faster.
  • Legal note: For client logos, confirm you have rights before uploading references. Commercial clarity matters.

When is Seedream not my pick? Highly stylized hand lettering. I switch to vector tools after generating the layout. Still, for AI images with accurate text inside photoreal scenes, Seedream 4.5 is now in my core toolkit.
