What is GPT-5.4 Image 2?

[GPT-5.4](https://openrouter.ai/openai/gpt-5.4) Image 2 combines OpenAI's GPT-5.4 model with state-of-the-art image generation capabilities from GPT Image 2.

It enables rich multimodal workflows, allowing users to seamlessly move between reasoning, coding, and...

GPT-5.4 Image 2 carries a 272K token window, uses the GPT tokenizer and is served by OpenAI. On Hoodgen it sits in the Reasoning tier of the model menu next to its siblings, so you can switch mid conversation without losing the thread.

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 $2 per million instead of $8, so stable prefixes get cheaper.
⌁
Seeds
A seed can be pinned so the same prompt is reproducible across test runs.

Thinking and reasoning capabilities

GPT-5.4 Image 2 can think before answering and exposes the effort level per request. Reasoning tokens bill as output at $15 per million, and the trace can be returned with include_reasoning.

What can you do with GPT-5.4 Image 2?

Debugging and root cause
Multi file failures where the model has to hold a causal chain before answering.
Architecture and planning
Design docs, migration plans and trade off analysis over long context.
Data analysis
Spreadsheets and logs read in one pass, then summarised with the numbers quoted back.
Agentic coding
Repo wide changes that need plan, edit and verify loops.

Prompt caching and how to cut the bill

Cached input bills at $2 per million instead of $8. Keep the system prompt and documents first and the changing question last, so every call hits the cache.

Privacy and data policy

  • On Hoodgen, prompts and attachments answer that request and stay in your conversation history so you can reopen it. They are not used to train models.
  • Requests route through OpenRouter to OpenAI and are covered by that provider's API terms.
  • Do not paste secrets or personal data you would not send to any hosted model.
