QA Manager at Synechron
AI coding assistant has transformed development speed and supports learning new languages
Any technology comes with two things, or rather anything in this world has both sides, good and bad. LLMs also have the same thing. The bad part is for a person who is 100% dependent on AI because they won't be able to learn more if they are 100% dependent on that. The main thing is that there has to be restraint from our side. I won't say it is from the tool side, but from our side, we need to learn and we need to work on it. We need to review the code. That is one thing that we need to do from our end. From a technology perspective, it is designed to help us out, and it is totally on our side of thinking about how exactly we are going to use that. There is not any area for improvement from the tool side, but it is from the users altogether. Users should not be 100% reliant on AI or any LLMs. They need to work on it and they need to review the code.
Uday Boya - PeerSpot reviewer
AI Research Enthusiast and Developer at ADP
AI workflows have transformed prototyping and coding productivity across my daily projects
There is a steeper learning curve for advanced agentic features that could be improved, and hallucinations should be reduced. The answers provided are long, which is impressive but not efficient for users needing rapid, crisp responses. Providing concise answers would improve the user experience. Google Gemini AI's UI code is too vague and the designs are not very appealing. Google Gemini AI can improve its UI code and address hallucination issues. The long answers provided can be tiresome to read, and the pricing is too high for individuals like me. These considerations led me to give a rating one point less than ten. Native GitHub or Vercel export could be integrated, and the context could be increased to over two million tokens. A simplified agentic setup for the UI could also help non-technical experts handle it more effectively.
