Kolibri 1
Kolibri 1 loads in 49.8 GB at Q4_K_M and decodes at the speed of its 3.5B active path, comfortably from 96 GB of memory, Macs included, starting at the MacBook Pro M5 Max 128GB. Below is the memory math we ran for it, the smallest card that fits, and the fastest machine we track.

How much memory does Kolibri 1 need?
Kolibri 1 is a 78.1B mixture-of-experts model (3.5B active per token) built for reasoning, german, long context. The weights alone take 49.8 GB at Q4_K_M; add context and the OS, and it belongs in the 96 GB memory class. Every number below comes from the ModelFit engine: speeds are estimates, labeled est., because we do not benchmark hardware ourselves.
KV = fp16 estimate (q8_0 cache roughly halves it). "Comfortable" = weights + KV within the engine's tiered budget (~70-85% of memory).

Frequently asked questions
How much memory does Kolibri 1 need?
49.8 GB for the Q4_K_M weights, plus ~0.3 GB of KV-cache at 16k context, about 50.1 GB total. Comfortable from 96 GB of VRAM or unified memory.
Does Kolibri 1 run on a Mac?
Yes, from the MacBook Pro M5 Max 128GB (est. 121 tok/s, typical error 10%). Unified memory means the RAM budget is the only limit.
What is the smallest GPU for Kolibri 1?
The NVIDIA RTX PRO 6000 Blackwell (96 GB VRAM) is the smallest tracked card that runs Kolibri 1 comfortably, est. 282 tok/s, typical error 15%.
