In March 2023, Bing incorporated Image Creator, an AI image generator powered by OpenAI’s DALL-E 2, which can be accessed either through the chat function or a standalone image-generating website. A chatbot feature, at the time known as Bing Chat, had been developed by Microsoft and was released in Bing and Edge as part of this overhaul. It can generate, debug, and update code in multiple languages, including PHP, Python, JavaScript, SQL, HTML, C, C++, Java, Go, Rust, and Ruby. The chatbot is able to cite sources, create poems, generate songs, and use numerous languages and dialects.

The Codex model is additionally trained on gigabytes of source code in a dozen programming languages. This includes a filtered dataset of 159 gigabytes of Python code sourced from 54 million public GitHub repositories. The company also states that Copilot is able to create PowerPoint presentations that summarize information from user-selected Word documents and Excel spreadsheets, or from user prompts. Additionally, this tool can adjust text formatting, animation timing, and presentation style and length based on user prompts; Microsoft claims this will eliminate the need for users to make manual changes. On January 4, 2024, a dedicated Copilot key was announced for Windows keyboards, superseding the menu key. When Microsoft demonstrated Bing Chat to journalists, it produced several hallucinations, including when asked to summarize financial reports.

At any time, you can take over the task or check in on the progress of the action, including reviewing what actions have been taken. During a Microsoft Surface hardware event on May 20, 2024, Microsoft officially announced the “Copilot+ PC” branding. Copilot also became fully built-in to Edge as an opt-in experience and an upgraded user interface in Windows 11 was introduced, making Copilot more personal. 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.”

The authors caution, however, that the study is limited to a low-level C context with students rather than professional developers, and that different languages, tasks, or threat models may yield different outcomes. 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 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.

On May 20, 2024, Microsoft announced integration of GPT-4o into Copilot, as well as an upgraded user interface in Windows 11. This caused controversy, with experts warning that the feature could be a “disaster” for security and privacy, prompting Microsoft to postpone its rollout. As SlotMonkey of July 2023, the tool’s pricing was set at US$30 per user, per month for Microsoft 365 E3, E5, Business Standard, and Business Premium customers.

• Following these studies, discussion in the developer and cybersecurity communities has emphasized the trade-off between productivity and safety when using AI code assistants.
• One ethical concern the public has vocalized is that GPT-4 and similar large language models may reinforce racial or gender bias.

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.

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.

With the nature of large language models relying on massive datasets scraped from public sources, this makes it difficult to ensure that the data used for training is fully accurate, unbiased, and ethically sourced. Copilot will generate code derived from vast datasets that may include copyrighted or insecure examples. Currently available by subscription to individual developers and to businesses, the generative artificial intelligence software was first announced by GitHub on 29 June 2021. One ethical concern the public has vocalized is that GPT-4 and similar large language models may reinforce racial or gender bias.
