Frequently Asked Questions

How much VRAM does Rocinante X 12B V1 need?

Rocinante X 12B V1 requires 8.1 GB of VRAM at Q4_K_M, or 25.2 GB at BF16. Full 131K context adds up to 26.4 GB (34.5 GB total).

VRAM = Weights + KV Cache + Overhead

Weights = 12.2B × 4.8 bits ÷ 8 = 7.3 GB

KV Cache + Overhead ≈ 0.8 GB (at 2K context + ~0.3 GB framework)

Fit ratings and hardware model lists check this model with room for a 16K-token context, which needs a little more memory.

KV Cache + Overhead ≈ 27.2 GB (at full 131K context)

Can I run Rocinante X 12B V1 on a Mac?

Yes — Mac Mini M2 Pro (16 GB) and 133 other Macs can run Rocinante X 12B V1. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 8.1 GB of usable unified memory (RAM minus macOS overhead).

Can I run Rocinante X 12B V1 locally?

Yes — Rocinante X 12B V1 can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.

How fast is Rocinante X 12B V1?

At Q4_K_M, Rocinante X 12B V1 can reach ~595 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~81 tok/s. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.

tok/s = (bandwidth GB/s ÷ model GB) × efficiency

Example: NVIDIA B200 → 8000 ÷ 8.07 × 0.65 = ~644 tok/s
