Frequently Asked Questions
- How much VRAM does SmolLM 135M Instruct FP32 need?
SmolLM 135M Instruct FP32 requires 0.4 GB of VRAM at Q4_K_M, or 0.6 GB at BF16.
VRAM = Weights + KV Cache + Overhead
Weights = 135M × 4.8 bits ÷ 8 = 0.1 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.
VRAM usage by quantization
Q4_K_M0.4 GB- What's the best quantization for SmolLM 135M Instruct FP32?
For SmolLM 135M Instruct FP32, 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 SmolLM 135M Instruct FP32 on a Mac?
Yes — MacBook Air 13" M3 (8 GB) and 38 other Macs can run SmolLM 135M Instruct FP32. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 0.4 GB of usable unified memory (RAM minus macOS overhead).
- Can I run SmolLM 135M Instruct FP32 locally?
Yes — SmolLM 135M Instruct FP32 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 SmolLM 135M Instruct FP32?
At Q4_K_M, SmolLM 135M Instruct FP32 can reach ~11163 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~1524 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 ÷ 0.43 × 0.65 = ~12093 tok/s
Estimated speed at Q4_K_M (0.4 GB)
~12093 tok/s~1524 tok/s~12093 tok/s~11163 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
- What's the download size of SmolLM 135M Instruct FP32?
At Q4_K_M, the download is about 0.08 GB. The full-precision BF16 version is 0.27 GB. The smallest option (Q2_K) is 0.06 GB.
- Which GPUs can run SmolLM 135M Instruct FP32?
