If similar code is open in your VS Code project, Copilot can draw context from those adjacent files. This can make it appear that the public model was trained on your private code, when in fact the context is drawn from local files. For example, this is how Copilot includes variable and method names relevant to your project in suggestions.
It’s also possible that your code – or very similar code – appears many times over in public repositories. While Copilot doesn’t suggest code from specific repositories, it does repeat patterns. The OpenAI codex model (from which Copilot is derived) works a lot like a translation tool. When you use Google to translate from English to Spanish, it’s not like the service has ever seen that particular sentence before. Instead, the translation service understands language patterns (i.e. syntax, semantics, common phrases). In the same way, Copilot translates from English to Python, Rust, JavaScript, etc. The model learns language patterns based on vast amounts of public data. Especially when a code fragment appears hundreds or thousands of times, the model can interpret it as a pattern. We’ve found this happens in <1% of suggestions. To ensure every suggestion is unique, Copilot offers a filter to block suggestions >150 characters that match public data. If you’re not already using the filter, I recommend turning it on by visiting the Copilot tab in user settings.
This is a new area of development, and we’re all learning. I’m personally spending a lot of time chatting with developers, copyright experts, and community stakeholders to understand the most responsible way to leverage LLMs. My biggest take-away: LLM maintainers (like GitHub) must transparently discuss the way models are built and implemented. There’s a lot of reverse-engineering happening in the community which leads to skepticism and the occasional misunderstanding. We’ll be working to improve on that front with more blog posts from our engineers and data scientists over the coming months.
They were highly skilled laborers who knew how to operate complex looms. When auto looms came along, factory owners decided they didn't want highly trained, knowledgeable workers they wanted highly disposable workers. The Luddites were happy to operate the new looms, they just wanted to realize some of the profit from the savings in labor along with the factory owners. When the factory owners said no, the Luddites smashed the new looms.
Genuinely, and I'm not trying to ask this with any snark, do you view the work you do as similar to the manufacturers of the auto looms? The opportunity to reduce labor but also further the strength of the owner vs the worker? I could see arguments being made both ways and I'm curious about how your thoughts fall.
But also this point is silly. Plenty of money and effort is risked and lost with no bailout. Bailouts are extremely unusual in the grand scheme of things.
