Frequently Asked Questions
- How much VRAM does Fable Coder 35B A3B need?
Fable Coder 35B A3B requires 72.3 GB of VRAM at BF16. Full 262K context adds up to 10.6 GB (82.9 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 36.0B × 16 bits ÷ 8 = 71.9 GB
KV Cache + Overhead ≈ 0.4 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 11 GB (at full 262K context)
VRAM usage by quantization
BF1672.3 GBBF16 + full context82.9 GB- Can NVIDIA GeForce RTX 5090 run Fable Coder 35B A3B?
No — Fable Coder 35B A3B requires at least 72.3 GB at BF16, which exceeds the NVIDIA GeForce RTX 5090's 32 GB of VRAM.
- Can I run Fable Coder 35B A3B on a Mac?
Fable Coder 35B A3B requires at least 72.3 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 Fable Coder 35B A3B locally?
Yes — Fable Coder 35B A3B can run locally on consumer hardware. At BF16 quantization it needs 72.3 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is Fable Coder 35B A3B?
At BF16, Fable Coder 35B A3B can reach ~61 tok/s on AMD Instinct MI350X. 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 ÷ 72.3 × 0.65 = ~72 tok/s
Estimated speed at BF16 (72.3 GB)
~72 tok/s~72 tok/s~61 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
- What's the download size of Fable Coder 35B A3B?
At BF16, the download is about 71.90 GB.
- Which GPUs can run Fable Coder 35B A3B?
No single consumer GPU has enough VRAM to run Fable Coder 35B A3B at BF16 (72.3 GB). Multi-GPU or professional hardware is required.
- Which devices can run Fable Coder 35B A3B?
19 devices with unified memory can run Fable Coder 35B A3B at BF16 (72.3 GB), including ASUS Ascent GX10, Asus ROG Flow Z13 (2025, Ryzen AI Max+ 395, 128 GB), 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.
