Hi HN.<p>I have been using JetBrains AI and GitHub Copilot over the last few months, as well as some lesser known ones like GitLab Duo and Tabnine.<p>In my testing I found:<p>* GitHub Copilot: most stable, highest quality code completions; however, the completions seem to have gotten worse over the months (using since many months now)
* Intellij AI: Interesting IDE integrations, however the code completion often simply does not work
* GitLab Duo: Only quickly checked out the code completion 2 months ago, quality was way worse than GitHub Copilot
* Tabnine: Interesting features (& control), however quality of the generated code also is not on the level of GitHub Copilot<p>What are your experiences so far? Do you have any recommendations? Especially interesting would be solutions that work on large codebases, offer fine tuning or knowledge base integrations (e.g. confluence)
Try Supermaven. Suggestions are much faster than any copilot, and it has the largest context of your project. A 1 million token context window. Also, you get access to GPT-4o, Claude 3.5 Sonnet, and GPT-4 out of the box
I tried Supermaven, and while it is certainly fast, it is more distracting to me since I have to read the suggestion, find it wrong, and type by myself (Python). Our FE guys who are doing React find it much more useful, probably because of the sheer amount of repetitive boilerplate React and JS require.
Most of these AI assistants are still works in progress. Sometimes, they provide correct suggestions; other times, they do not. This is understandable, as generative AI still requires significant improvement in understanding context and predicting the most appropriate design, architecture, and solutions. These tools can be more time-consuming than manually editing or refactoring the code. I use these tools when I find it difficult to understand certain logic, as they explain it well. However, we still have to wait to generate production-ready code.
Been hearing great things about Cursor, and its been impressive in my few days of use.<p><a href="https://www.cursor.com" rel="nofollow">https://www.cursor.com</a>
I’ve looked at several alternatives over the past year and Copilot is the best I’ve seen so far overall when you factor in ease of use, price to performance etc.<p>There may be services which generates code better, but at the end of the day you still need to review and touch up anything that is generated.<p>Copilots chat integration in Jetbrain IDE’s has also been great at helping me discover language features/functions, especially when learning new languages.
I tried JetBrains AI and Github Copilot and ended up just removing them altogether.<p>The autocomplete when it works is wonderful but more often than not, I need to delete and type it again. Most of the time I know what I want to type and not using AI saved me the time it took me delete and try again.<p>I did like the chat window but it wasn't enough for me to keep it. Maybe you can't teach this old dog new tricks :(
