One thing to note is that the tutorial generation depends largely on Gemini 2.5 Pro. Its code understanding ability is very good, combined with its large 1M context window for a holistic understanding of the code. This leads to very satisfactory tutorial results.
However, Gemini 2.5 Pro was released just late last month. Since Komment.ai launched earlier this year, I don't think models at that time could generate results of that quality.
I haven't switched back. At least for my use cases it's been meeting my expectations.
I haven't tried Microsoft's new 1.58 bit model but it may be a great swap out for sentencellm, the legendary all-MiniLM-L6-v2.
I found that if I'm unfamiliar with the knowledge domain I'm mostly using AI but then as I dive in the ratio of AI to human changes to the point where it's AI at 0 and it's all human.
Basically AI wins at day 1 but isn't any better at day 50. If this can change then it's the next step
