GPT-5.2 pushes harder on real work: code, tools, long context.

More useful for shipping work, especially with structure.

What changed
Improved performance on multi-step projects (tool use + longer context)
Better at generating spreadsheets/presentations and handling structured tasks
More reliable code generation and iterative edits
Who it affects
Builders
Analysts
People using AI for real deliverables (not chatting)
What to do now
Give the model structured inputs (tables, bullet requirements, acceptance criteria)
Ask for a plan first, then execution (reduces mistakes)
Request output as JSON/Markdown tables when you need consistency
