MEET THE MODELS
Get familiar with GPT Image 2.5 and Seedream 4.5
At a glance, both GPT Image 2.5 (GPT 2.5) and Seedream 4.5 turn a prompt into a high-quality image, but with different strengths. GPT 2.5 is OpenAI's precision model - sharp detail, ~99% text accuracy, and exact multi-turn editing. Seedream 4.5 is ByteDance's unified model that merges generation and editing in one workflow, with dense multilingual text and strong cost efficiency. Try them both in our AI Playground and AI Image Generator.
TEXT RENDERING
Compare text accuracy and typography
Both models are text-rendering leaders. GPT Image 2.5 hits ~99% text accuracy for crisp English headlines and small type. Seedream 4.5 specializes in dense, multilingual text - including Chinese - across posters, packaging, and infographics with consistent formatting. For maximum English accuracy, GPT Image 2.5 leads; for dense multilingual layouts, Seedream 4.5 is exceptional.
EDITING & WORKFLOW
Precise edits vs unified generation and editing
GPT Image 2.5 makes surgical single-element edits and stays stable across a long multi-turn session, with up to 16 references. Seedream 4.5 unifies generation and editing in one model - describe changes in plain language and reference up to 14 images to swap products, move text, or adjust lighting without leaving the workflow. GPT Image 2.5 favors precision; Seedream 4.5 favors an all-in-one flow.
RESOLUTION & COST
Resolution ceilings and cost efficiency
GPT Image 2.5 outputs up to 4K (3840px max edge) with new xhigh and max quality tiers for extra headroom. Seedream 4.5 runs 1K-4K at standard output and up to 8K when you need extreme detail for print - all at roughly $0.04 per image, about 4x more cost-efficient than many competitors. For premium precision, GPT Image 2.5; for high-volume, high-res value, Seedream 4.5.
PICK YOUR MODEL
Choose GPT Image 2.5 or Seedream 4.5 for your workflow
Choose GPT Image 2.5 for precision work - product edits, legible posters, and photoreal campaigns where detail and English text accuracy matter. Choose Seedream 4.5 for a unified generate-and-edit flow, dense multilingual text, and high-volume value at up to 8K. Choose Picsart to use both - compare GPT Image 2.5 and Seedream 4.5 side by side and pick the best model for each project.
