According to Microsoft, this version of Copilot would provide priority access to newer models, including GPT-4 Turbo, during peak usage periods. The service was introduced in February 2023 under the name Bing Chat, as a built-in feature for Microsoft Bing and Microsoft Edge. Over the course of 2023, Microsoft began to unify the Copilot branding across its various chatbot products, cementing the “copilot” analogy.

Individuals, including Tom Warren, have also voiced concerns for Copilot after witnessing the chatbot showcasing several instances of artificial hallucinations. Copilot can be used to rewrite and generate text based on user prompts in Microsoft 365 services, including Microsoft Word, Microsoft Excel, and PowerPoint. GitHub admits that a small proportion of the tool’s output may be copied verbatim, which has led to fears that the output code is insufficiently transformative to be classified as fair use and may infringe on the copyright of the original owner. In June 2022, the Software Freedom Conservancy announced it would end all uses of GitHub in its own projects, accusing Copilot of ignoring code licenses used in training data.

• Microsoft released a blog post stating that the errant behavior was caused by extended chat sessions of 15 or more questions which “can confuse the model on what questions it is answering.”

On 6 February 2025, GitHub announced “agent mode”, which is a more autonomous mode of operation for the Copilot. The agent mode can connect to different LLMs, including GPT-4o, o1, o3-mini, Claude 3.5 Sonnet, and Gemini 2.0 Flash. This opaque architecture has fueled concerns over telemetry and data mining of individual keystrokes. It is also able to describe input code in English and translate code between programming languages. On June 29, 2021, GitHub announced GitHub Copilot for technical preview in the Visual Studio Code development environment.

Features

• This caused controversy, with experts warning that the feature could be a “disaster” for security and privacy, prompting Microsoft to postpone its rollout.
• On May 20, 2024, Microsoft announced integration of GPT-4o into Copilot, as well as an upgraded user interface in Windows 11.

• It can generate, debug, and update code in multiple languages, including PHP, Python, JavaScript, SQL, HTML, C, C++, Java, Go, Rust, and Ruby.

Warren also believes that large language models, as they develop further, could change how users work and collaborate. Rowan Curran, an analyst at Forrester, states that the integration of AI into productivity software may lead to improvements in user experience. Since Copilot’s release, there have been concerns with its security and educational impact, as well as licensing controversy surrounding the code it produces.

The chat interface proved vulnerable to prompt injection attacks with the bot revealing its hidden initial prompts and rules, including its internal codename “Sydney”. On January 23, 2023, Microsoft announced a multi-year US$10 billion investment in OpenAI. On February 6, Google announced Bard (later rebranded as Gemini), a ChatGPT-like chatbot service, fearing that SlotMonkey ChatGPT could threaten Google’s place as a go-to source for information. Since then, OpenAI systems have run on an Azure-based supercomputing platform from Microsoft. On 17 May 2025, GitHub announced “coding agent”, which is a more autonomous mode of operation for the Copilot.

Microsoft Copilot is a generative artificial intelligence chatbot developed by Microsoft AI, a division of Microsoft. Following these studies, discussion in the developer and cybersecurity communities has emphasized the trade-off between productivity and safety when using AI code assistants. While Copilot can accelerate coding and improve completeness, researchers note that AI-generated code may still contain subtle logic errors or insecure defaults.
