Microsoft Copilot is now rolling out GPT-5-powered Smart mode to free users, and early tests reveal a surprising twist: the company is allowing more generous use of the model’s deep reasoning “Thinking” capability than OpenAI’s own ChatGPT Free tier. Starting August 7, 2025, Windows 11 and Windows 10 users who access Copilot via the web or dedicated app have started seeing a new “Smart” toggle that automatically decides when to engage GPT-5’s more compute-intensive reasoning path. While OpenAI officially limits ChatGPT Free users to just one GPT-5 Thinking message per day, WindowsLatest’s hands-on testing found that Copilot permitted at least five Thinking invocations within 24 hours without an explicit cutoff—a fivefold increase that signals Microsoft’s aggressive push to make advanced AI a default OS feature.

How Smart Mode Routes GPT-5 Behind the Scenes

GPT-5, the latest large language model from OpenAI, was designed with built-in reasoning capabilities that can be toggled on demand. The model family includes a fast, cost-effective variant for straightforward queries and a deeper “Thinking” mode that processes multi-step logic, code analysis, and complex planning. In ChatGPT, users must manually choose between standard and thinking modes—and hitting the daily limit triggers an automatic fallback to a less capable model.

Microsoft’s Copilot takes a different approach. The new Smart mode uses a real‑time model router—hosted on Azure—that inspects each prompt to decide whether it needs a quick answer or a full reasoning pass. The router runs server‑side, meaning no Copilot app update is required to flip on GPT‑5. WindowsLatest confirmed that the Smart toggle appeared in Copilot version 1.25073.146.0 without any client refresh, underscoring Microsoft’s ability to alter model access across its entire consumer base instantly.

When the router detects a prompt that would benefit from deeper thought—such as debugging Python code, drafting legal clauses, or synthesizing a multi‑document summary—it routes that request to GPT‑5 Thinking. For simpler questions, it sticks with the standard, faster path. The user never sees a model picker; they just get what Microsoft believes is the most appropriate response quality.

Rate Limits: Copilot vs. ChatGPT Free

OpenAI publishes clear usage caps for GPT‑5 in ChatGPT. According to official documentation:

  • ChatGPT Free: a limited number of standard GPT‑5 messages in a fixed time window, plus just one GPT‑5 Thinking message per day.
  • ChatGPT Plus ($20/month): up to 160 messages every three hours for standard GPT‑5, and a 10x increase in Thinking capacity (roughly 10 Thinking messages per day).
  • Team and Pro tiers: near‑unlimited access subject to abuse guardrails.

Microsoft has not released a comparable public table for Copilot. The only data point comes from WindowsLatest’s testing: they were able to invoke GPT‑5 Thinking five times in a single day before Copilot silently stopped using the reasoning mode. Even then, no explicit “limit exhausted” message appeared; responses simply became less thorough, suggesting the router had switched to a cheaper model.

That is a dramatically different experience from ChatGPT Free’s hard one‑per‑day Thinking cap. Moreover, during the test, standard (non‑Thinking) queries appeared to use full GPT‑5 rather than GPT‑5‑mini, based on output quality—another departure from ChatGPT’s documented behavior, where free‑tier standard messages are often served by GPT‑5‑mini after a small window.

WindowsLatest’s observances are anecdotal, not policy. Microsoft may tweak these internal limits at any time, and users in different regions or with different account types could see different behavior. Still, the initial evidence points to a deliberate strategy: give Copilot more headroom for reasoning than the company’s own model provider offers direct to consumers.

Why Microsoft Can Afford More Generous Limits

Three structural factors explain Microsoft’s ability to loosen the reins.

Vertical integration with Azure. Microsoft hosts Copilot’s GPT‑5 instances on its own Azure infrastructure. It can optimize compute scheduling, cache frequent results, and spread loads across its global data center fleet in ways that OpenAI’s multi‑tenant ChatGPT service cannot. Azure’s massive scale and the revenue cushion provided by enterprise customers buying M365 Copilot and Azure AI services allow the free consumer tier to consume more resources without cratering costs.

Strategic product lock‑in. By embedding GPT‑5—and its most impressive reasoning mode—directly into Windows, Microsoft turns the operating system into the easiest place to get advanced AI assistance. A user who discovers that Copilot handles complex coding help or vacation itinerary planning for free is less likely to pay for a separate ChatGPT Plus subscription, and more likely to stay within the Microsoft ecosystem for other tasks. The move deepens the competitive moat around Windows and lays a natural on‑ramp to paid Copilot tiers for businesses.

Metering that masks real consumption. Copilot’s router may break a single user prompt into multiple internal calls, some of which activate Thinking for only part of the response generation. If Microsoft counts a “Thinking message” as a complete conversation turn with visible reasoning output, rather than every internal inference step, users could trigger nuanced reasoning many times without consuming their quota as quickly as they would in ChatGPT, where every thinking toggle is explicitly counted.

How to Access GPT‑5 Smart Mode Right Now

Using GPT‑5 in Copilot requires no special insider build or payment.

  1. Open copilot.microsoft.com in any browser (Microsoft suggests Edge for fastest routing) or launch the Copilot app from the Microsoft Store on a Windows 10 or 11 device.
  2. Sign in with a personal Microsoft account. Enterprise accounts may have different provisioning depending on administrator settings.
  3. Look for the “Smart” label at the top of the compose box. If it’s present, you’re already on GPT‑5. No toggle is necessary; the router works automatically.
  4. For complex tasks, you can nudge the system to trigger Thinking by using phrases like “please think step‑by‑step” or “show your chain of thought.” Note that WindowsLatest’s experience suggests these forced nudges still count against the daily Thinking quota.

If Smart mode doesn’t appear immediately, waiting a few days is the most reliable fix. The feature rollout is server‑side and staggered. Clearing the cache or reinstalling the app rarely helps because model selection is determined entirely in the backend.

What GPT‑5 Actually Delivers for Everyday Work

The practical upside for Windows users is immediate. Copilot can now serve as a surprisingly capable coding assistant—debugging Python scripts, refactoring SQL queries, or explaining legacy code—without hitting a paywall. In WindowsLatest’s test, Copilot accurately answered 10 complex Python questions in a row, invoking Thinking three times out of 10 and nailing every response. Drafting, summarizing, and planning tasks that previously required a separate AI subscription are now available by default on every Windows PC.

Because the integration is OS‑level, it also unlocks context that web‑based chatbots lack. When granted permission, Copilot can reason over documents in OneDrive, emails in Outlook, and calendar entries—turning it into a digital assistant that spans work and personal spheres. Microsoft’s official communications confirm that GPT‑5 is already active inside Microsoft 365 Copilot, GitHub Copilot, and Copilot Studio, meaning enterprise customers get the same reasoning boost across their workflows.

The Hidden Risks of Opaque Quotas and Over‑Reliance

The generosity comes with a trade‑off: uncertainty. Without a documented usage meter, users cannot tell how many Thinking messages remain. WindowsLatest’s testers hit the internal cap without warning; responses simply became shorter and less insightful. For someone relying on Copilot to finish a critical task, a silent downgrade mid‑conversation could derail productivity.

Quality consistency is another concern. While early impressions suggest standard queries route to full GPT‑5, Microsoft’s private routing logic could switch users to a smaller model at any time if demand spikes. The company’s history with Copilot features—such as the now‑retired GPT‑4 Turbo mode—shows that free‑tier capabilities can shrink without notice.

Business users face added complexity. Copilot’s ability to process email, documents, and calendar data raises immediate policy questions for regulated industries. IT administrators must review data governance, residency, and compliance settings in Microsoft 365 before allowing broad access. Rate limits, no matter how generous, are not a substitute for proper data loss prevention controls.

Safety, Security, and Regulatory Hurdles

Microsoft notes that its AI Red Team subjected GPT‑5’s reasoning model to rigorous security evaluation, and the model showed strong resistance across tested attack vectors like malware generation or fraud automation. These internal results are encouraging but not a panacea. Advanced reasoning models can produce more authoritative‑sounding errors, and wider access amplifies the risk of misinformation spreading through high‑confidence responses.

Relaxed rate limits also lower the barrier for abuse. While Microsoft has enterprise‑grade content filtering, abuse monitoring at consumer scale is harder. Users have already documented ways to bypass Copilot’s content restrictions through prompt engineering, and more daily Thinking capacity gives attackers more room to probe those weaknesses.

From a regulatory perspective, bundling a cutting‑edge free AI into a dominant operating system will raise eyebrows in Brussels, Washington, and beyond. Antitrust enforcers have already targeted Microsoft for its Teams and Edge practices; adding a built‑in, free‑to‑use GPT‑5 that outshines rivals could be framed as unfair competition. The European Union’s AI Act and various national data protection laws add further scrutiny over how Copilot handles personal and enterprise data.

The Bigger Picture: Microsoft vs. OpenAI’s Diverging Paths

Microsoft’s decision to give free Copilot users more GPT‑5 Thinking leeway than ChatGPT Free underscores a deepening divergence between the two companies, despite their deep partnership. OpenAI’s constraints reflect the need to ration expensive compute across a massive, direct‑to‑consumer user base—its free tier must be sustainable on its own economics. Microsoft can subsidize Copilot’s compute through Azure profits and the upsell potential of its enterprise offerings.

This bifurcation may reshape user behavior. A Windows user who gets five Thinking sessions a day for free has little incentive to pay OpenAI $20 monthly for roughly twice that capacity delivered through a separate interface. Third‑party developers building on OpenAI’s API will also need to factor Copilot into their competitive landscape. If the OS can natively answer complex queries, apps that previously justified their value through exclusive AI reasoning support must find new differentiation.

At the same time, the move pressures other platform owners. Google’s Gemini integration in ChromeOS and Apple’s Apple Intelligence push may accelerate as each company seeks to anchor users with built‑in, cutting‑edge AI.

What to Watch Next

Several developments will determine whether Copilot’s GPT‑5 generosity sticks:

  • Published quota tables. A formal usage document, akin to OpenAI’s help article, would eliminate the current guessing game and let users plan around limits.
  • Telemetry on abuse. If either Microsoft or OpenAI releases data on how increased Copilot access affects misuse rates, the industry will get a clearer picture of the risk/benefit calculus.
  • Regulatory action. Formal inquiries into Microsoft’s AI bundling, particularly in the EU, could force changes to how Copilot is featured in Windows.
  • Enterprise feedback. How IT departments react to the expanded capabilities will shape Microsoft’s willingness to maintain generous free‑tier access long‑term.

For now, Windows users have reason to celebrate. The deepest reasoning model on the market just became a standard part of their desktop, with practical limits that far exceed what even the model’s creator offers for free. Prudence, verification of outputs, and awareness that limits can shift overnight remain essential—but for the first time, advanced AI thinking isn’t locked behind a paywall; it’s sitting right in the taskbar.
