Frequently Asked Questions
- How much VRAM does SmolLM2 70M need?
SmolLM2 70M requires 0.5 GB of VRAM at BF16.
VRAM = Weights + KV Cache + Overhead
Weights = 69M × 16 bits ÷ 8 = 0.1 GB
KV Cache + Overhead ≈ 0.4 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 0.5 GB (at full 8K context)
VRAM usage by quantization
BF160.5 GBBF16 + full context0.6 GB- Can I run SmolLM2 70M on a Mac?
SmolLM2 70M requires at least 0.5 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 SmolLM2 70M locally?
Yes — SmolLM2 70M can run locally on consumer hardware. At BF16 quantization it needs 0.5 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is SmolLM2 70M?
At BF16, SmolLM2 70M can reach ~6202 tok/s on AMD Instinct MI300X. On NVIDIA GeForce RTX 4090: ~1394 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 ÷ 0.5 × 0.55 = ~6202 tok/s
Estimated speed at BF16 (0.5 GB)
~6202 tok/s~1394 tok/s~4636 tok/s~3835 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
