Frequently Asked Questions
- How much VRAM does SmolLM2 70M need?
SmolLM2 70M requires 0.4 GB of VRAM at Q4_K_M, or 0.5 GB at BF16.
VRAM = Weights + KV Cache + Overhead
Weights = 69M × 4.8 bits ÷ 8 = 0 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
Q4_K_M0.4 GBQ4_K_M + full context0.5 GB- What's the best quantization for SmolLM2 70M?
For SmolLM2 70M, Q4_K_M (0.4 GB) offers the best balance of quality and VRAM usage. Q5_K_M (0.4 GB) provides better quality if you have the VRAM. The smallest option is Q2_K at 0.4 GB.

- Can I run SmolLM2 70M on a Mac?
SmolLM2 70M requires at least 0.4 GB at Q2_K, 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 Q4_K_M quantization it needs 0.4 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is SmolLM2 70M?
At Q4_K_M, SmolLM2 70M can reach ~11579 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~1724 tok/s. 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 ÷ 0.4 × 0.65 = ~13684 tok/s
Estimated speed at Q4_K_M (0.4 GB)
~13684 tok/s~1724 tok/s~13684 tok/s~11579 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
- What's the download size of SmolLM2 70M?
At Q4_K_M, the download is about 0.04 GB. The full-precision BF16 version is 0.14 GB. The smallest option (Q2_K) is 0.03 GB.
- Which GPUs can run SmolLM2 70M?
