GPT-5.5 pushes from assistant to real-work agent
Threat
Thin productivity SaaS gets squeezed when a general model can plan, use tools, check work, and complete multi-step jobs.
What changed
The model moves from helping with a step to carrying more of the work across tools until the job is finished.
GPT-5.5 is a pressure event for horizontal productivity software. The threat is not one feature; it is the model's ability to move across writing, coding, data, and tool use in one flow.
Categories hit
- AI document assistants: Summaries, drafts, spreadsheets, and reports become generic agent tasks rather than standalone product surfaces.
- Coding copilots outside the IDE: When the general assistant can code, debug, use tools, and verify outputs, separate coding helpers need deeper workflow ownership.
