Mapika12B~8 GB VRAM at Q4_K_M

Decider 12B Vision — VRAM & /v1/systemone setup

Written by Jakub Rusinowski · Last updated

Mapika's 12B decision model on Gemma 4 12B with a merged LoRA, for text and images; about 24 GB in bf16. Served by decider.serve_vllm (decider-ai 1.10.0).

Decider 12B Vision needs about 8 GB of VRAM at Q4_K_M — quantized weights plus framework overhead, before any KV cache. On Apple Silicon that figure comes out of unified memory.

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. Image tokens are not modelled: each image adds to the prompt, so a request with images needs more memory than these rows.

Decider 12B Vision — frequently asked questions

What is Decider 12B Vision?

Decider 12B Vision 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 12B Vision locally?

Served by decider.serve_vllm. This model does not run in Ollama. Start it with: `pip install "decider-ai>=1.10.0"`.

How much memory does Decider 12B Vision need?

About 8 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.
