Can Desktop PC · 2× GeForce RTX 3090 (48 GB) · 128 GB RAM run Kolibri-1 (78B-A3.5B)?
48 GB VRAM + 128 GB RAM · 936 GB/s memory bandwidth · Kolibri-1 (78B-A3.5B) has 78.1B parameters (3.46B active per token).
Short answer
Yes, excellent for chat; borderline for coding in a repository.
Best quantization for chat: Q4_K_M (45 GB of weights) on Ollama. Generation: 160–270 tok/s, leaving about 1.5 GB free for your other apps.
How it rates for each workload
Same model and machine, different jobs. Agents and long documents send far bigger prompts than chat, so they need much more speed and memory.
