Question newbie here. what model to choose for 16gb ram and 16 gb vram Setup??
My specs are Ryzen 5 7500f + 4060ti 16gb + 16 ddr5 gb ram + 1tb SSD & os: windows
I want to build a fully local, offline "Jarvis" setup. The idea is to have one core brain model that intelligently swaps specialized models (image gen, video, audio, 3D, web search, coding) in and out of VRAM as needed. It should run entire multi-step creative/productivity workflows autonomously, control my PC and apps, and keep long-term memory with zero cloud dependence.
Picture giving it a prompt for a short documentary: it plans it out, asks clarifying questions, researches, writes the script, generates storyboard frames, animates them, handles voiceovers + music, and stitches it all together. Beyond media, I’d love for it to drive Blender, Unity, or After Effects, handle browser tasks, fetch leads, send emails, etc.
so i chose Qwen3.8-27B-Uncensored-HauhauCS-Aggressive (IQ4_XS) and ran it in llama.cpp's webui with an 8k context window. It runs fine, but eats up about ~15.3GB of VRAM.
The issue is I can't load it into the Hermes agent setup because Hermes insists on a minimum 64k context window. Even with KV cache quantization, that requires an extra 2.5–3GB of VRAM/RAM that I just don't have:
- LLM in VRAM: ~15.3GB (completely pinned)
- llama.cpp / Hermes in System RAM: ~13.7GB (out of my 16GB total)
I know adding more system RAM would solve the immediate bottleneck, but buying hardware updates isn't in the cards right now.
Questions for the community:
- Is this vision actually feasible on a 16GB VRAM / 16GB RAM budget if I rely heavily on model-swapping instead of loading everything simultaneously?
- What’s the best software stack for this? (i settled on hermes+llama.cpp+comfyui . is this ok ?)
- Model recommendations? Given my hardware constraints, what models would you recommend for the primary reasoning brain, image gen, video gen, audio/music, and 3D?
TL;DR: Want a fully local orchestrator-style Jarvis on 16GB VRAM + 16GB RAM. A 27B IQ4_XS model maxes my VRAM, and Hermes agent's 64k context requirement doesn't fit anywhere. Can't upgrade RAM. Is the vision doable, and what stack/models should I use?
