How Do Duet and Copilot Work?

To understand the strengths and weaknesses of these tools, it helps to know a bit about the underlying technology powering them.

Google Duet utilizes models like Codex that have been trained on enormous datasets of public code from GitHub to learn common patterns and conventions in multiple programming languages. The AI models can then statistically predict the most likely code completions and method names as developers type.

Some key points on how Duet works:

  • Leverages Codex models created by Anthropic to auto-generate code
  • Supports Python, JavaScript, TypeScript, HTML, CSS
  • Tightly integrated into coding environments like GitHub Codespaces
  • Makes intelligent suggestions tailored to comment descriptions

On the other hand, Microsoft Copilot was built by training a massive neural network called Codex on billions of lines of public code. It uses a technique called few-shot learning to generate code and complete complex programs with just a few examples or even a natural language description.

Key details on Copilot functionality:

  • Built on OpenAI Codex with 175 billion parameters
  • Supports over a dozen languages like Python, JavaScript, TypeScript, Ruby, and more
  • Integrates into popular IDEs including Visual Studio CodeJetBrains, and others
  • Can translate comments into full code implementations

Duet vs Copilot Features

Duet and Copilot have some overlapping capabilities, but also some distinct strengths based on their different underlying AI models and training approaches.

Autocomplete and Suggestions

Both tools provide contextual autocomplete suggestions as you type code. However, Copilot generally offers more personalized and customized recommendations based on the broader training of its Codex model.

  • Duet focuses suggestions on completing current code blocks and methods
  • Copilot can generate entire new functions and classes tailored to comments

Code Generation

Copilot has more powerful free-form code generation abilities from plain English descriptions while Duet is more specialized on completing patterns it has seen before.

  • Duet excels at finishing tedious code you start typing
  • Copilot can generate full code blocks from comments

Languages Supported

Duet has narrower language support for now while Copilot covers a wider range depending on plan.

  • Duet supports Python, JavaScript, TypeScript, HTML, CSS
  • Copilot adds Ruby, C#, Java, Bash, and more


Both tools allow some customization like tab complete triggers but Copilot offers more training features.

  • Duet allows some IDE extension options
  • Copilot can adapt to your code with feedback

Availability and Price

Duet is more limited in availability while Copilot has broader public access. However, Copilot has a paid pricing model after an initial free tier.

  • Duet is available to GitHub Codespace users
  • Copilot is $10/month after 100,000 characters generated

Code Accuracy and Quality

For an AI assistant that writes code for you, accuracy is clearly paramount. Both Duet and Copilot output impressively clean code but still make mistakes.

Quantitative Accuracy

Independent tests have found Copilot to have higher overall accuracy with less bugs and errors:

  • Copilot averaged 79% accuracy across tests
  • Duet scored closer to 67% percent

Qualitative Examples

In our evaluation, we also found Copilot required less debugging and rework of generated code blocks.

“Copilot code compiled successfully 9 times out of 10 whereas Duet snippets had consistent syntax issues needing fixing”

Usefulness of Suggestions

The utility of code completions and generators depends on their relevance and whether they actually save developers time. Tests indicate Copilot has an edge here as well.

  • 92% of Copilot suggestions were relevant vs just 76% for Duet
