Mhh, I don't observe this. Hard to say.
You probably know this already, but be sure to don't reuse a AI conversation with different context (Having a single chat for both cooking and coding is nono). Often starting a new chat is better.
If it forgets what you said it sounds a bit like you use one chat for too long, or you use a too small model (fast, air, haiku, nano etc.)
