GitHub Copilot vs. Google Gemini vs. Tabnine

Copilit is fantastic at the following: 1. Solving simple, well-defined problems, such as implementing an algorithm, manipulating a data structure, or string manipulation and regex. 2. Implementing simple APIs that are mainly CRUD in nature, with moderate business logic inside them, which may involve some processing or passing the data through an algorithm. 3. Implementation of well-defined activities, such as implementing a connection to an Oracle DB using Hibernate or JDBC, or implementing boilerplate code for a backend service to listen to Kafka events. It is not that great when it comes to understanding and implementing code in a proprietary DSL. It struggles when implementing a major feature across a complex codebase. I believe developers should also adopt the trust-but-verify paradigm when expecting highly secure or regulated code from GitHub Copilot.

Gemini is fantastic for receiving quick answers to questions where accuracy is not paramount. It is great for brainstorming ideas. It is also fantastic for analysing large swathes of unformatted data and finding correlations. Gemini can also transcribe handwriting and audio files making it excellent for formative assessment. It can also now create Google Slides which is great for lesson planning. Gemini is only as good as the prompts you provide it with though so you must remember to be exact with your prompts to get the best outputs.

• The new image editing functionality surprised me
• In general, file loading is better than in other AI programs
• I think it's somewhat faster than other AI programs, or at least that's the impression it usually gives
• Features like canvas and deep research are very interesting

• The only issue I faced is the context token size, it can be increase.
• Sometime with agent mode it takes too much time, which can be reduced but I understand it also depends on the complexity of the given task.

• Faces in generated images can be kind of scary looking, deformed.
• When asking for specific text in an image, it often generates funky randomly spelled text instead.
• Tried a bulk image search with uploaded png files to find the same images online and the links it provided were 404 errors instead.

I feel that GitHub Copilot's overall usability is good due to its tight integration with Visual Studio and the workspace. However, developers expect greater ease of use, as there is a learning curve to realize productivity gains with the tool fully. I think there is room for improvement in GitHub Copilot's UI integration within Visual Studio.

It's standard usability interface - no problems or challenges using it. I do prefer Claude still because of the different options/modes you can toggle on and off. I don't think Gemini has those options. It's a great daily companion for quick problem solving but not great for larger projects or conversations

It is useful that copilot integrates so well with vscode, which is a very common IDE. I used Tabnine for a little while but it was not that intuitive, and did not seem as helpful as GitHub copilot was. I have enjoyed GitHub copilot a lot, especially the ease of hitting the tab key and seeing quick progress in my tasks.

Gemini seems very simple to use, veyr similar to ChatGPT, I wish they did have a capability such as ChatGPT projects one, so one can separate topics easily, it's very customizable, where I believe it defeats the others is that, is already very simple to use all of Google ecosystem, such as Drive, docs, sheets and else

• Our ROI of the purchase of Copilot was met in less than a day. The timesave cannot be overstated
• Programmer boredom/dissatisfaction is down because of less repetetive crud work.
