Microsoft Copilot's new version, Deucalion, offers Copilot Pro capabilities, for free

Microsoft Copilot is currently rolling out a new version called, Deucalion, on Edge, after some users noticed a shift in behavior which caused it to offer better solutions and answers to tasks.

Mikhail Parakhin, leader of the Windows and Web Experiences Team, which is responsible for Copilot, confirmed the improvement is due to a new Copilot version being rolled out.

We are continually improving Microsoft Copilot, testing a new version of the base model in a flight. Fun fact: its internal name is “Deucalion” (the son of Prometheus in Greek mythology).

The new version can provide complex and well-researched outputs even in the Balance mode, which is known to be a bit reserved. In a post made to X, it seems that some users are already on this new version, while others might have to wait.

When asked what is Deucalion capable of, Parakhin answered that the new Copilot version makes use of multiple AI models to provide users with the best outputs. Some of these models are coming from OpenAI, while others are trained in-house, by Microsoft.

The whole system is a combination of several models and Search internal sub-systems. Some of the models are the finetuned OpenAI models, some – OpenAI models as is, some Microsoft-trained ones.

Microsoft is offering Copilot Pro features to users through Deucalion

The Deucalion version is close to Copilot Pro in nature because it is offering advanced AI capabilities to users on Edge, for free.

Some users noted that Microsoft Copilot is also capable of multilingual speech, and Parakhin confirmed that this feature is also part of the new version, although it might increase latency overall.

Yes, that’s what we are trying to bring in. It increases latency a bit though, trying to optimize.

However, Copilot enthusiasts will get several Pro features, including more complex and well-thought-out outputs from the free version, which is more than welcome for those who can’t afford to pay $20/month for Copilot Pro.

Parakhin has yet to unveil more information about this new flight, but Microsoft will most probably announce it in the next days or weeks.

But for now, it seems that some users experience complex outputs from Copilot on Edge when the Balanced mode is selected. The version is gradually rolling out, so it might take a while until everybody has access to it.
