Local setup, “text generation webui”, TheBloke/Mixtral-8x7B-Instruct-v0.1-GGUF (Q4_K_M) on HF. You can run it on a decent intel cpu, takes around 32.5GB of ram including os (8gb for me). GPU with tensorcores can speed up few layers if you have one, but isn’t required. I get around 2.5-3 t/s with 8700 and 4070ti, that’s enough for chats that require some thinking.

Edit: I was using 2k window, a larger one would probably eat more ram. But even with 2k it didn’t feel like it loses context or something.
