AI Pro Reasoning on Raq.com now uses GPT-5.4 Pro. It builds on the existing workflow for document analysis, follow-up questions, Dual mode, and shareable reports, now with a stronger model behind the work.
OpenAI describes GPT-5.4 as its most capable model for professional work. Improvements span spreadsheets, presentations, documents, and deep web research. That makes this upgrade especially relevant for long reports, technical comparisons, research-heavy tasks, and structured business analysis.
These are the most relevant public Pro-to-Pro comparisons from OpenAI's GPT-5.4 release materials. All figures are GPT-5.4 Pro vs GPT-5.2 Pro.
Source: OpenAI GPT-5.4 release materials. BrowseComp was measured at a later date and also reflects changes in the search system.
All five comparisons point the same way: stronger business work, stronger research, and stronger multi-step reasoning.
Expect better synthesis across large sets of information, stronger structure in long reports, and better performance when a task depends on careful research rather than a single quick answer. This is an inference from OpenAI's published evaluations and capability notes, not a direct Raq.com internal measurement.
Raq.com already positions AI Pro Reasoning for deep research, complex analysis, and detailed reports. GPT-5.4 Pro raises the ceiling on that work without changing what the tool is for.
