The free version can only really provide suggestions for small projects not exceeding 200KB in file sizes. Once you hit the limit, it only provide suggestions partially. This is due to the way TabNine works — it builds an index of your project and gives suggestions based on that, and 200KB is the index limit for the free version. See More
It uses a lot of memory for a text-editor feature, and that's on top of whatever text editor you're using. Open a few instances of VS Code + TabNine + Firefox and you can easily cause your computer to start heavily swapping.

TabNine can suggest completions extremely fast — they pop-up immediately after you type a letter with no noticeable lag, compared to some other completion plugins. It promises ~20ms response time when auto-completing anything, and it's built on Rust where speed and memory-efficiency are first-class citizens of the language and ecosystem. See More
