Frequently Asked Questions

How much VRAM does TildeOpen 30B need?

TildeOpen 30B requires 19.2 GB of VRAM at Q4_K_M, or 62.2 GB at BF16. Full 66K context adds up to 15.6 GB (34.8 GB total).

VRAM = Weights + KV Cache + Overhead

Weights = 30.7B × 4.8 bits ÷ 8 = 18.4 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 ≈ 16.4 GB (at full 66K context)

Can I run TildeOpen 30B on a Mac?

Yes — Mac Mini M5 Pro (24 GB) and 106 other Macs can run TildeOpen 30B. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 19.2 GB of usable unified memory (RAM minus macOS overhead).

Can I run TildeOpen 30B locally?

Yes — TildeOpen 30B can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.

How fast is TildeOpen 30B?

At Q4_K_M, TildeOpen 30B can reach ~250 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~34 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 ÷ 19.2 × 0.65 = ~271 tok/s

Estimated speed at Q4_K_M (19.2 GB)

~271 tok/s
