Frequently Asked Questions
- How much VRAM does Apodex 1.0 4B SFT need?
Apodex 1.0 4B SFT requires 9.8 GB of VRAM at BF16. Full 262K context adds up to 21.3 GB (31.1 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 4.7B × 16 bits ÷ 8 = 9.3 GB
KV Cache + Overhead ≈ 0.5 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 21.8 GB (at full 262K context)
VRAM usage by quantization
BF169.8 GBBF16 + full context31.1 GB- Can I run Apodex 1.0 4B SFT on a Mac?
Apodex 1.0 4B SFT requires at least 9.8 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 Apodex 1.0 4B SFT locally?
Yes — Apodex 1.0 4B SFT can run locally on consumer hardware. At BF16 quantization it needs 9.8 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is Apodex 1.0 4B SFT?
At BF16, Apodex 1.0 4B SFT can reach ~298 tok/s on AMD Instinct MI300X. On NVIDIA GeForce RTX 4090: ~67 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 MI300X → 5300 ÷ 9.8 × 0.55 = ~298 tok/s
Estimated speed at BF16 (9.8 GB)
~298 tok/s~67 tok/s~223 tok/s~184 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
