The year 2023 saw Microsoft betting big on artificial intelligence and its partnership with OpenAI to make Copilot a reality. The company has invested billions of dollars in this area, and they want to make sure customers know about their products and, more importantly, use them with the best experience.
Microsoft is now trying to boost the performance of its Copilot synthetic AI chatbot with some notable additions. For example, free Copilot users can now access OpenAI's GPT-4 Turbo large language model.
Previously, users could only access GPT-4 Turbo LLM when they purchased Microsoft's Copilot Pro service for $20 a month. However, in a post on the X (formerly Twitter) account today, Microsoft's head of Advertising and Web Services, Mikhail Parakhin, announced that GPT-4 Turbo is now available to Copilot users for free as part of the Redmond company's efforts to provide users with an enhanced experience.
GPT-4 Turbo was first announced by OpenAI in November 2023. The biggest advantage of this new platform is that it gives users access to a much larger 128L context window, meaning that a single text prompt can now be up to 300 pages long. To put that in perspective, while previous versions were limited to 3,000 words, GPT-4 Turbo accepts inputs of up to 300 pages, meaning users can ask the tool to summarize an entire book.
Additionally, GPT-4 Turbo also supports images and can convert text to speech based on DALL-E 3 technology. Microsoft added ChatGPT-4 Turbo support last December with a Copilot Pro subscription, and now it's completely free.
Parakhin added that Copilot Pro subscribers who want to continue using the older GPT-4 LLM in Copilot can click a toggle button to allow them to switch to that model.

This week is actually a pretty big one for Copilot. On Monday, Microsoft confirmed that all Copilot Pro users now have access to the Copilot GPT Builder. The new tool allows users to create their own custom chatbots that can answer more specific questions on targeted topics without any programming knowledge. Copilot Pro subscribers can then share their custom chatbots with anyone, even those without a Copilot Pro account, on both mobile and PC.
