Decider 4B — VRAM & /v1/systemone setup
Autor: Jakub Rusinowski · Ostatnia aktualizacja:
Model decyzyjny 4B od Mapika na Qwen3.5-4B-Base, obsługiwany przez decider.serve ze zgodnym z TypeSafe /v1/systemone.
Decider 4B potrzebuje około 4 GB VRAM przy Q4_K_M — skwantyzowane wagi plus narzut frameworka, bez pamięci podręcznej KV. Na Apple Silicon ta wartość pochodzi z pamięci zunifikowanej.

Hardware fit
Weights plus overhead plus the KV cache at a 8,192-token prompt, on NVIDIA RTX 4090 (24 GB). A publisher build is sized from its file; the other rows are modelled at a standard quant. Decision requests are short, so no long-context figure is shown.

Decider 4B — najczęściej zadawane pytania
What is Decider 4B?
Decider 4B is a decision model: you send it a state and typed questions (choice, yes/no/unknown, or a score) and it returns one answer per question with a probability for every option. It is not a chat model.
How do I run Decider 4B locally?
Decider 4B does not run in Ollama. Served by decider.serve. This model does not run in Ollama. See the setup guide for servers other than Ollama.
How much memory does Decider 4B need?
About 4 GB for the weights plus overhead at Q4_K_M, before the prompt's KV cache. Decision prompts are short, so the cache stays small.
How accurate is Decider 4B?
Its published score is on the community Decision Index 0.2.1, which its authors did not build. It is not a calibration guarantee: test on your own examples.
