Frequently Asked Questions
How much VRAM does Nandi Mini V1.1 600M Intermediate Checkpoint 400GT need?
Nandi Mini V1.1 600M Intermediate Checkpoint 400GT requires 1.8 GB of VRAM at BF16.
VRAM = Weights + KV Cache + Overhead
Weights = 649M × 16 bits ÷ 8 = 1.3 GB
KV Cache + Overhead ≈ 0.5 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.
VRAM usage by quantization
Can I run Nandi Mini V1.1 600M Intermediate Checkpoint 400GT on a Mac?
Yes — MacBook Air 13" M3 (8 GB) and 145 other Macs can run Nandi Mini V1.1 600M Intermediate Checkpoint 400GT. Apple Silicon uses unified memory, so the model shares RAM with the system. At BF16 you need at least 1.8 GB of usable unified memory (RAM minus macOS overhead).
Can I run Nandi Mini V1.1 600M Intermediate Checkpoint 400GT locally?
Yes — Nandi Mini V1.1 600M Intermediate Checkpoint 400GT can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.
How fast is Nandi Mini V1.1 600M Intermediate Checkpoint 400GT?
At BF16, Nandi Mini V1.1 600M Intermediate Checkpoint 400GT can reach ~2697 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~368 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 ÷ 1.78 × 0.65 = ~2921 tok/s
Estimated speed at BF16 (1.8 GB)
Real-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
