RTX 3090 user compares Ollama, Unsloth Studio and llama.cpp for local AI
NWSpitfire · reddit · 2026-07-26
A Reddit user is rebuilding a local AI stack on an R7 5700X, 48GB RAM, and RTX 3090 24GB after an NVIDIA driver update broke their Ubuntu install.
They compared several options:
- Ollama + OpenWebUI: stable, but slow with models like Gemma 4 and Qwen3.6, and sometimes sluggish with web/MCP.
- Unsloth Studio: faster, with tool/search calls working well, but unstable and prone to crashes.
- llama.cpp: part of the wider set of suggestions people keep recommending for this class of machine.
The user mainly wants a reliable stack for coding, web/PDF lookup, and config generation, plus model recommendations that run well within 24GB VRAM and 48GB system RAM.
