Where to Use GPT-5.4 Image 2
Coding and code review
Generate, debug, and review code across languages, reading whole files or repos in a single prompt.
Agentic and multi-step workflows
Reliable tool-calling and instruction-following suit agent loops that plan, call tools, and iterate.
Complex reasoning
Extended reasoning improves reliability on multi-step math, logic, and technical analysis.
Long-document analysis
Summarize and extract from contracts, papers, and reports without aggressive chunking.

GPT-5.4 Image 2 is documented as suited to rich multimodal workflows that move between reasoning, coding, and visual generation in one interaction. It is also suited to image editing with reference images, since it accepts up to 16 reference images in one request. It is described as accepting images, text, and files such as PDFs as input while returning images and text, which makes it suitable for workflows that combine document and visual inputs. It is also positioned for image-only workloads when paired with the provider’s dedicated image API.
