Frequently Asked Questions

How much VRAM does Apex 35B v1.0 need?

Apex 35B v1.0 requires 21.9 GB of VRAM at Q4_K_M, or 72.3 GB at BF16. Full 262K context adds up to 2.6 GB (24.6 GB total).

VRAM = Weights + KV Cache + Overhead

Weights = 36.0B × 4.8 bits ÷ 8 = 21.6 GB

KV Cache + Overhead ≈ 0.3 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 ≈ 2.9 GB (at full 262K context)

Can I run Apex 35B v1.0 on a Mac?

Yes — Mac Mini M5 Pro (24 GB) and 106 other Macs can run Apex 35B v1.0, the smallest at Q3_K_M. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 21.9 GB of usable unified memory (RAM minus macOS overhead), from Mac Studio M1 Max (32 GB).

Can I run Apex 35B v1.0 locally?

Yes — Apex 35B v1.0 can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.

How fast is Apex 35B v1.0?

At Q4_K_M, Apex 35B v1.0 can reach ~116 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~151 tok/s. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.

tok/s = 1000 ÷ (active GB ÷ (bandwidth GB/s × efficiency) × 1000 + layers × routing ms)

Mixture-of-Experts: just the active experts get read for each token, along with a fixed routing cost per layer.

Example: NVIDIA B200 → 2.9 GB active ÷ (8000 × 0.65) = 0.557 ms, plus 40 layers × 0.055 ms = 2.200 ms, so 1000 ÷ 2.757 ms = ~363 tok/s

Estimated speed at Q4_K_M (21.9 GB)

~363 tok/s
~151 tok/s
~363 tok/s
~322 tok/s

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

What's the download size of Apex 35B v1.0?

At Q4_K_M, the download is about 21.57 GB. The full-precision BF16 version is 71.90 GB. The smallest option (Q2_K) is 15.28 GB.

Which GPUs can run Apex 35B v1.0?

7 consumer GPUs can run Apex 35B v1.0 at Q4_K_M. Top options include AMD Radeon RX 7900 XTX, NVIDIA GeForce RTX 3090.

Which devices can run Apex 35B v1.0?

100 devices with unified memory can run Apex 35B v1.0 at Q4_K_M (21.9 GB), including AMD Ryzen AI 9 HX 370 (Strix Point) Laptop, ASUS Ascent GX10, Beelink GTR9 Pro (Ryzen AI Max+ 395, 128 GB), Framework Desktop (Ryzen AI Max+ 395, 128 GB). Apple Silicon Macs use unified memory shared between CPU and GPU, making them well-suited for local LLM inference.
