Frequently Asked Questions

How much VRAM does Triplex need?

Triplex requires 8.8 GB of VRAM at BF16. Full 131K context adds up to 50.7 GB (59.5 GB total).

VRAM = Weights + KV Cache + Overhead

Weights = 3.8B × 16 bits ÷ 8 = 7.6 GB

KV Cache + Overhead 1.2 GB (at 2K context + ~0.3 GB framework)

KV Cache + Overhead 51.9 GB (at full 131K context)

Can I run Triplex on a Mac?

Triplex requires at least 8.8 GB at BF16, which exceeds the unified memory of most consumer Macs. You would need a Mac Studio or Mac Pro with a high-memory configuration.

Can I run Triplex locally?

Yes — Triplex can run locally on consumer hardware. At BF16 quantization it needs 8.8 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.

How fast is Triplex?

At BF16, Triplex can reach ~333 tok/s on AMD Instinct MI300X. On NVIDIA GeForce RTX 4090: ~75 tok/s. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.

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

Example: AMD Instinct MI300X5300 ÷ 8.8 × 0.55 = ~333 tok/s

Estimated speed at BF16 (8.8 GB)

~333 tok/s
~75 tok/s
~249 tok/s
~206 tok/s

Real-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
