Is new bing the same as copilot?

The new Bing and Copilot are not the same, but they are deeply interconnected products from Microsoft that share a common underlying technology and are part of a unified corporate strategy. The distinction is primarily one of branding, interface, and specific integration points rather than a fundamental difference in core capability. The "new Bing," launched in early 2023, was Microsoft's first major consumer-facing product to integrate the advanced GPT-4 model, rebranding its search engine as an AI-powered conversational assistant accessible through a dedicated chat interface within the Edge browser and Bing.com. Microsoft Copilot, introduced later, evolved as the overarching brand for its AI assistants across multiple platforms and products, effectively subsuming the Bing Chat experience into a broader ecosystem. Therefore, the AI you once accessed as "Bing Chat" is now most directly represented by the standalone service called "Copilot," which is available on the web and via a dedicated application, even as the Bing search engine itself continues to offer a similar chat functionality.

The mechanism behind this branding shift reflects Microsoft's strategic pivot from anchoring its AI to a specific product like Bing toward positioning "Copilot" as a ubiquitous, multi-platform companion. Technologically, both services are powered by similar large language model foundations, primarily OpenAI's GPT-4 and later models, augmented by Microsoft's own Prometheus suite of technologies for grounding responses in web search results. The key operational difference lies in their access points and default behaviors. The conversational AI within the Bing search interface is tightly coupled with a traditional search session, emphasizing citation of web sources and current information. The standalone Copilot application and website, while also capable of web-grounded search, present themselves more as a general-purpose AI assistant, with a cleaner interface and features like longer conversation turns and image generation via DALL-E 3 more prominently integrated. Underneath, the core reasoning engine and safety mitigations are largely consistent.

The implications of this naming and structural evolution are significant for users and the competitive landscape. For the average user, it creates some confusion, as the capabilities appear identical whether accessed via Bing.com, the Copilot website, or the Windows Copilot sidebar. However, Microsoft's clear intention is to decouple the advanced AI experience from the Bing search brand to encourage adoption across its entire software suite, including Microsoft 365 applications, where "Copilot" functions as an in-app productivity aid. This allows Microsoft to segment its offerings: "Bing with AI" remains a search-first, web-centric experience, while the broader Copilot brand can evolve into an operating system-level assistant and a premium enterprise service. Consequently, while the free AI chat service formerly known as Bing Chat is operationally the same as the free tier of Copilot, Microsoft is using the Copilot moniker to build a more expansive and commercially layered ecosystem around its generative AI technology.
