02 · Overview

What is GPT-5 Image?

[GPT-5](https://openrouter.ai/openai/gpt-5) Image combines OpenAI's GPT-5 model with state-of-the-art image generation capabilities.

It offers major improvements in reasoning, code quality, and user experience while incorporating GPT Image 1's superior instruction following,...

GPT-5 Image carries a 400K token window, uses the GPT tokenizer and is served by OpenAI. On Hoodgen it sits in the Coding tier of the model menu next to its siblings, so you can switch mid conversation without losing the thread.

04 · Capabilities

Features and capabilities

◈

Thinking control

Reasoning effort can be dialled per request, so one model covers deep analysis and fast chat.

{ }

Structured outputs

Schema constrained JSON with response_format, so no parse and retry loop in your code.

◉

Vision

Screenshots, charts and photographed documents are read at the text token rate.

▤

Files and PDFs

Documents go in as files rather than pasted text, keeping layout and tables intact.

⚡

Prompt caching

Cached input costs $1.25 per million instead of $10, so stable prefixes get cheaper.

⌁

Seeds

A seed can be pinned so the same prompt is reproducible across test runs.

05 · Reasoning

Thinking and reasoning capabilities

GPT-5 Image can think before answering and exposes the effort level per request. Reasoning tokens bill as output at $10 per million, and the trace can be returned with include_reasoning.

Level	First token	Cost per task	Best for
Measured	n/a	n/a	Artificial Analysis measures the default reasoning configuration
Low effort	Faster	Lower	Chat, autocomplete, classification
High effort	Slower	Higher	Debugging, planning, multi step agents

07 · Use cases

What can you do with GPT-5 Image?

Code generation

New modules, tests and migrations from a written spec.

Refactoring

Cross file renames and API migrations with the whole repo in context.

Code review

Diff review with reasons, not just lint output.

Pairing

In editor loops inside the Hoodgen Coding workspace.

08 · Cost levers

Prompt caching and how to cut the bill

Cached input bills at $1.25 per million instead of $10. Keep the system prompt and documents first and the changing question last, so every call hits the cache.
