GPT Image 2: current image-generation model on Okou
A current image-generation model with Built-in access through Okou.
Image / Text-to-image / Image edit
A current image-generation model from OpenAI, available in Okou's public model catalog.
What is GPT Image 2?
April 2026 · OpenAI's newer GPT Image model, positioned above GPT Image 1 for prompt adherence and flexible output sizing.
Select GPT Image 2 in Settings > Built-in tools before generating. Naming a model in a prompt does not change this setting. Generation uses your selected image model and is billed in credits.
Specs at a glance
GPT Image 2 pricing
Relative Built-in credit cost. Actual charges depend on usage and settings; check the app for current prices.
How GPT Image 2 behaves in practice
Observed behaviour from production agent runs.
Prompt adherence
The main reason to pick GPT Image 2 over GPT Image 1 is stricter execution of detailed prompts, especially when the brief includes composition, aspect ratio and style constraints.
Edit flows
Supports image-to-image edits and masks. Use it when a workflow needs to preserve a source image while changing a described region.
Cost
More expensive than GPT Image 1 at medium and high tiers. Keep draft loops on lower quality and reserve high quality for final output.
Best agent tasks for GPT Image 2
The agent that needs exact prompt following
When the prompt has specific framing, style or size requirements, GPT Image 2 is the safer OpenAI-image choice than GPT Image 1.
The image workflow that needs multiple aspect ratios
Marketing, social and website assets often need square, portrait and landscape outputs. GPT Image 2 fits those workflows without changing the prompt style.
The OpenAI-stack edit loop
If an agent is already using OpenAI models for planning and copy, GPT Image 2 keeps image generation in the same prompt-following family.
When to skip GPT Image 2
Skip GPT Image 2 when cost dominates or when true transparent-background output is required. GPT Image 1, GPT Image 1.5 or Seedream 4 may be better depending on the constraint.
GPT Image 2 vs other models
GPT Image 2 vs GPT Image 1
GPT Image 2 is the newer, more flexible model with stronger prompt adherence. GPT Image 1 remains cheaper at common medium-standard settings and is still strong for stylised illustration.
GPT Image 2 vs Seedream 4
Seedream 4 is cheaper and photoreal-leaning. GPT Image 2 is the better OpenAI-stack choice when prompt adherence, edit workflow and flexible sizing matter more than lowest cost.
Bottom line: should you use GPT Image 2?
Pick GPT Image 2 when you want OpenAI image generation with stronger prompt adherence and flexible sizing. Use GPT Image 1 or Seedream 4 when cost is the dominant constraint.
Frequently asked questions
When should I use GPT Image 2 instead of GPT Image 1?
Use GPT Image 2 for stricter prompt adherence and flexible sizing. Use GPT Image 1 when the brief is simpler or cost matters more.
