Copilot

Microsoft

Microsoft's assistant, in Windows, Edge, Bing and Microsoft 365.

Overview

Microsoft's assistant, in Windows, Edge, Bing and Microsoft 365.

Versions

Copilot Smart with GPT-5

Microsoft’s consumer Copilot help page identifies GPT-5 as the model powering Smart mode. This applies to the documented personal-account experience, not automatically to Microsoft 365 Copilot, GitHub Copilot, or a GeckoCheck capture.

Think Deeper

A reasoning-oriented conversation mode powered by OpenAI reasoning models. Microsoft does not name a fixed checkpoint in this help page; the mode should not be presented as a separate numbered model.

Quick response, Search, and Study and learn

Other documented conversation modes emphasize speed, current web information, or guided learning. Copilot is a product that routes through different experiences rather than one publicly fixed model version.

Capabilities

Web search with citations

Search mode retrieves up-to-date information from the web and presents citations for further checking.

Deeper reasoning

Think Deeper is intended for complex questions, nuanced comparisons, and detailed problem-solving.

Contextual conversation and writing

Smart mode supports nuanced understanding, natural conversation, explanations, and creative problem-solving.

Guided learning

Study and learn explains concepts step by step, supports follow-up questions, and can quiz users. Some modes require signing in, and access depends on the supported region and language.

Copilot in GeckoCheck

GeckoCheck reads how Copilot answers the queries a brand cares about: whether it names the brand, how it describes it, who it names instead, and which pages it cites.

Each model is read and graded on its own, because each answers differently. A brand's plan sets which models it tracks.
