Starcoder2 3B — Hardware Requirements & GPU Compatibility

ChatCode

StarCoder2-3B is BigCode's 3-billion-parameter base code model, trained from scratch on 17 programming languages drawn from The Stack v2 using a fill-in-the-middle objective over more than 3 trillion tokens. It is a pretrained checkpoint rather than an instruction-tuned assistant, so it completes and continues code rather than following natural-language commands, and it uses grouped-query attention with a sliding-window mechanism for efficiency. It has a 16,384 token context window and is released under the BigCode OpenRAIL-M license, which carries use-based restrictions rather than being fully permissive. At 3 billion parameters, it runs easily on almost any modern laptop or consumer GPU, even without a high-end card, whether quantized or run at half precision.

Frequently Asked Questions

How much VRAM does Starcoder2 3B need?

Starcoder2 3B requires 2.2 GB of VRAM at Q4_K_M, or 6.4 GB at BF16.

VRAM = Weights + KV Cache + Overhead

Weights = 3.0B × 4.8 bits ÷ 8 = 1.8 GB

KV Cache + Overhead ≈ 0.4 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.

KV Cache + Overhead ≈ 0.8 GB (at full 16K context)

Can I run Starcoder2 3B on a Mac?

Yes — MacBook Air 13" M3 (8 GB) and 145 other Macs can run Starcoder2 3B. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 2.2 GB of usable unified memory (RAM minus macOS overhead).

Can I run Starcoder2 3B locally?

Yes — Starcoder2 3B can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.

How fast is Starcoder2 3B?

At Q4_K_M, Starcoder2 3B can reach ~2202 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~301 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 ÷ 2.18 × 0.65 = ~2385 tok/s

Estimated speed at Q4_K_M (2.2 GB)

~2385 tok/s
~301 tok/s
~2385 tok/s
~2202 tok/s

Real-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
