Your smarter work partner: how GPT-5 and Microsoft Copilot elevate everyday productivity

On August 7, 2025, OpenAI officially released GPT-5, its most advanced and unified model yet. It combines speed, deep reasoning, and precision in a single system. The model uses a dual-core approach: a high-throughput "fast" core for quick responses and a more analytical "thinking" core for complex problems, with an intelligent router automatically choosing the right one in real time. 

This means users no longer have to manually switch modes. GPT-5 adapts naturally, whether you are asking a quick question, seeking a creative idea, or working on an in-depth analysis. 

GPT-5 also significantly reduces the risk of hallucinations. Factual errors are down by 45% compared to GPT-4o and by 80% compared to the “o3” reasoning model. It also introduces safe completions, aiming to provide helpful responses even in sensitive cases instead of defaulting to refusals. 

Integration into Microsoft Copilot 

On the same day as GPT-5’s release, Microsoft integrated it into Microsoft 365 Copilot across all markets and platforms, including web, Windows, Mac, and mobile. Highlights include: 

• Immediate availability. Microsoft 365 Copilot users can now access GPT-5 instantly via the new “Try GPT-5” button in Copilot Chat.
• Smart mode. Automatic selection of the right model for the task removes the need for manual switching.
• Copilot Studio support. GPT-5 can now power custom AI agents for business workflows.
• Human-like responses. The model provides a better understanding of context, fosters more creativity, and yields less generic answers, with improved tone and relevance. 

“GPT-5 is faster, more responsive, and uses tokens more efficiently than previous models. It understands user intent with greater accuracy, generates code more effectively, and communicates in a more natural, human-like way. The model also exhibits fewer hallucinations and automatically adjusts its depth of reasoning based on the prompt, eliminating the need for manual cues like “Think deeper.” 
For our clients and users, this means AI is becoming not only more powerful but also more accessible and practical for daily work. The overall improvements make a compelling case for exploring AI integration in workflows and solutions - even for those who haven't tried it yet,” says Rolands Vārna, Squalio Cloud Solution Consultant. 

Why this matters for Microsoft Copilot users 

With GPT-5 now fully integrated into Microsoft 365 Copilot, AI is operating at its highest capacity yet for everyday use. Copilot can respond faster, understand context more deeply, and adapt automatically to the complexity of each request. Whether drafting documents, analyzing data, generating code, or finding creative solutions, it now delivers results that feel more human, precise, and relevant. 

This is not just an incremental upgrade; it is a shift toward AI that works seamlessly in the background, anticipating needs and delivering answers that fit naturally into the flow of work. For Microsoft 365 users, it means Copilot is no longer just a helpful assistant. It has become a reliable, adaptable partner that elevates productivity across every task, every day.
