Do not blindly delete your older models, some are still precious

I have deleted tons and tons of older models to make space since I can't afford storage anymore. Easily 10TB... Anyways, I have been considering deleting DeepSeekV3.2 but decide to run it one more time. I have a problem I have been brainstorming about and have chatted locally with K3, Qwen3.8-2.4T, MiniMaxM3, GLM5.2 and today I decided to see how DSV3.2 respond. Surprisingly it responded the best with absolute details and familiarity and specs of the hardware I was asking about. What I'm saying is that the world knowledge is amazing. The newer models are definitely smarter, better agentic, tool calling capable, long horizon etc, but some of the older models seems to be really clear and comprehensive. I know I deleted DS-0324 and K2 but now thinking of bringing them back for prose/writing. Don't blindly delete your older models, some of them are still worth their weight literally and will be for a while.
