Direct Writing and Code Blocks for Seamless Document Drafting
Leverage auto-formatting writing blocks for long-form draft creation.
Stop using the legacy Canvas feature; instead, prompt GPT-5.5 Instant to generate outputs using the new Writing and Code blocks for better readability.
The Scenario
You need to generate a long-form document or a complex piece of code without the distraction of a cluttered chat interface.
Before & after
Users previously had to manually copy-paste long, messy chat text into a word processor and reformat it for readability, taking 10–15 minutes.
The model now automatically formats long outputs into clean, scrollable writing blocks, making it ready for use in roughly 30 seconds.
The Prompt
Write a [TYPE OF DOCUMENT, E.G., 1,500-WORD PROJECT PROPOSAL] for [PROJECT NAME]. Use writing blocks to keep the layout clean and easy to read.
Opening the 'Canvas' feature is no longer necessary for GPT-5.5 Instant. Writing and code snippets are automatically handled via 'writing blocks' and 'code blocks' that are easier to navigate and read compared to standard chat bubbles.
