I ran DeepSeek and Llama and Mistral at home on my consumer grade gaming PC.
With a little tweaking of the system prompts and configuring web search, I was running a local LLM that felt pretty darn close to the commercial LLMs.
With this technology out in the open internet where you can download the models in a few hours I don't see how the commercial AI companies are going to last. If selling "Artificial Intelligence" subscriptions is all your company does for revenue, you're screwed.
I downloaded and ran an LLM that I could have a conversation with and feed basic coding problems to for basically zero dollars and ran it on my puny gaming machine...puny compared to enterprise-class hardware. It would be trivial for a company with a very moderate budget to buy some servers and start running their own LLMs that they can use to feed all the PII and HIPPA data they want.
